Physics in cancer diagnostics is changing lives. As we have often heard, Precision, and accuracy are crucial in the treatment of cancer. Especially with PET-MRI imaging, it is possible to find a tumor’s precise situation. Doctors can plan radiation in a way that treats cancer and spares as much healthy tissue as possible. Modern cancer treatments make full use of physics, which is a basic area of scientific research. Moreover, modern technologies use physics to find tumors. They look at their behavior and come up with new treatments. Physics applications allow imaging inside the body. They target cancerous cells. These breakthroughs in cancer diagnostics and treatment are revolutionizing radiation oncology. Core physics principles are contributing a lot to breakthroughs in all aspects of cancer diagnosis. Such efforts also use innovative imaging techniques like positron emission tomography (PET) and magnetic resonance imaging (MRI) to direct treatment. In this article, we will cover radiation oncology, where radiation is delivered powerfully and precisely for radiation safety. Physics in Cancer Diagnostics: Making Scans Work Just like finding hidden things in a maze can be challenging, similarly detecting tumors inside the body is equally difficult. Doctors use advanced technologies to detect these cancers without needing to open the body. Physics helps make these tools. It’s the science of how things work in the world, like light, magnets, and tiny particles. Physics helps the doctors to diagnose where cancer might be. It helps them to understand how different parts of the body look using special pictures. Two big ways physics helps are with PET scans and MRI scans. These are like super-powered cameras that show what’s happening inside our body. Look at this picture. It shows how PET and MRI use different ideas from physics to make treatments. They help doctors make good plans to treat cancer. 1. Positron Emission Tomography (PET) Researchers use Positron Emission Tomography as a functional tool in imaging to offer a detailed analysis of activities in the metabolism of tissues. The physics starts with the radiotracer; a molecule, which bears radioisotope labeled for positron-emitting radionuclide. When a radiotracer is introduced into a body, it will accumulate in those regions which are metabolically active. For example, fast-growing cancer cells. The emitted positron travels a short distance. It then annihilates with an electron. This produces two gamma rays that are ejected and travel in opposite directions. PET scanners detect these coincident gamma rays and complex algorithms, drawing from physics principles of radiation detection and reconstruction, reconstruct the origin of the annihilation event. This enables clinicians to quantify metabolic uptake in various regions. The nuclear medicine physics informs the design of these radiotracers and the conceptualization of their half-lives. See examples of common radiotracers and their properties in the table below. Radiotracer (Isotope) Common Use Example (Molecule) Half-life Fluorine-18 (¹⁸F) FDG (Glucose analog) Approx. 110 mins Carbon-11 (¹¹C) Choline, Methionine Approx. 20 mins Nitrogen-13 (¹³N) Ammonia Approx. 10 mins Oxygen-15 (¹⁵O) Water Approx. 2 mins Gallium-68 (⁶⁸Ga) DOTA compounds Approx. 68 mins Copper-64 (⁶⁴Cu) Various targeting molecules Approx. 12.7 mins 2. Magnetic resonance imaging (MRI) Scans Magnetic resonance imaging is a procedure to make pictures of the inside of our body. It does not use X-rays; although, it relies on magnets and radio waves. Our body is mostly made of water and water has small parts like magnets. The big magnet on the MRI machine makes these small parts line up in a single direction. Then, the machine transmits radio waves that send these small parts. When they return to their original position, they emit their own radio signals. The MRI machine hears such signals. One body part will report back different from another body part. This makes the machine draw a clear picture. Doctors can view tumors in position and watch how water and blood flow from it, thus knowing the tumor better. The pictures are changing with a slider for you to see. When the radio waves are altered, the picture looks changed, and it allows the doctors to see more about the tumor. Such imaging techniques are of great help in treatment plans. It is all diagnostic radiology. Latest Developments in Radiation Oncology Doctors have to treat the cancer after finding it. Once doctors detect cancer, they have to cure it. Radiation oncology is a technique of treating cancer through a high form of energy like X-rays, or other small particles. The idea is to damage or destroy cancer cells; while leaving normal cells unharmed. Physics is very important to ensure that the energy reaches the right place, with the right force. Physics assists doctors to point the energy as a superhero would to point a beam of laser. They use it to decide that the radiation dose is appropriate for the tumor. The infographic demonstrates how the energy enters the body. Radiation treatment can be given using physics in two main forms. 1. External Beam Radiation Therapy (EBRT) There is a primary category of radiation therapy known as external beam radiation therapy. An outside large machine beams energy to the tumor. The standard machine known is called a linear accelerator, or LINAC. These energy beams are manufactured using the same deep understanding of physics in cancer diagnostics that helps us see tumors so clearly. Physics also designs the beams. It’s as if you shone a flashlight through a cut-out shape. Physics gives a shape to the energy beam such that only the tumor suffers the beam. This spares the healthy areas of the body and lowers side effects. Radiation protection is the prevention of the energy from harming others to keep everyone safe. 2. Nuclear Medicine Approaches Nuclear medicine uses radioactive materials to help doctors see inside the body and, from time to time, also to treat some health problems. Y-90 or I-131 is bonded to molecules in targeted therapy. They connect to cancer cells and concentrate the radiation in the tumor. I-131 therapy is applied when treating patients after surgery for thyroid cancer. It helps clean up any

How Organic Chemistry Is Tackling Microplastic Pollution for Cleaner Water
Clean water is a great blessing. It is equally essential for both humans and animals. We all understand the importance of clean water. Schools, colleges, and communities emphasize its significance, although we see polluted our water has become today. We often see images of our beaches filled with plastic bottles and bags. It doesn’t stop here. Tiny plastic particles, even smaller as a grain of rice, are polluting our rivers, oceans, and even our drinking water. These tiny particles are known as microplastics, and they are the most critical issue of our time. But, we know that this is not just a problem of today. The future of our coming generations also depends on it. Hence, addressing this issue is crucial. Organic chemistry is playing a major role in microplastic pollution. Scientists are exploring innovative solutions to control this environmental crisis. In this article, we will explore how organic chemistry is used to control microplastic pollution and purifies our drinking water. We will first understand that what are microplastics and how they affect human health. Then, we will explore how organic chemistry is playing its role. We will examine the new solutions being developed. There will be some examples included. We will also discuss the challenges we face and explore how we can play our part in it. So, let’s get started. Microplastics and Their Effect on the Environment Microplastics are tiny particles with a size of less than five millimeters, much like a sesame seed. The question arises, where do they come from? How they are formed? The simple answer is that they are found everywhere. As for how they are formed, let’s dive into the details. They are found in cosmetics, which are particularly popular among women. They exist in clothing fibers like polyester, and even in our favorite hoodies, plastic bottles. Over time, when this martial break down, they generate these tiny particles. According to a study, more than 24 trillion pieces of microplastics are floating on the world’s oceans. Microplastics equally impact the health of both humans and animals. Because they are made of chemical compounds, when ingested, they can lead to various diseases. Aquatic creatures, including fish and turtles, when searching for food often consume microplastics as their food. These chemicals settle in their stomachs and cause various infections in their reproductive and immune systems. Similarly, when humans drink polluted water, it gives rise to various diseases. Up to this point, we have understood that what are microplastics and how significantly they can impact our health. Now, let’s check how organic chemistry can offer solutions to these challenges. The Role of Organic Chemistry in Microplastic Pollution As we know, organic chemistry is a branch of science that focuses on the study of carbon related molecules, and guess what? Plastics are also made of carbons. This is the point, where organic chemistry is considered as an excellent tool for fighting microplastic pollution. Chemists use their skills to design new materials, like sustainable packaging materials, that can serve as alternatives to plastic materials. They are also constantly working on innovative solutions to remove these tiny particles found in the environment. Because they understand how these plastics are created at the molecular level, they are in a strong position. This knowledge helps them come up with clever solutions to tackle their impact. Are you eager as I am to learn about these solutions? So, let’s dive in and check out some of these exciting ideas. 1. Creating eco-friendly options that break down naturally I think it is a magnificent approach to create a type of plastic that naturally decomposes. On the other hand, regular plastic takes hundreds of years to break down. Keeping this in mind, organic chemists developed a material known as Polylactic Acid, which is made from corn scratch. Now it is widely used in packaging materials, because it offers a biodegradable choice compared to traditional plastics. Another material, Polyhydroxyalkanoates, which is derived from bacteria. This versatile material can be used in a wide range of applications, from packaging to medical devices. It is true that biodegradable materials can help in reducing microplastics in the environment. However, challenge remains there in scaling up their production to meet global demand. Moreover, ensuring that these materials will decompose in all environments, including marine ecosystems, is a difficult task. It requires further research and development. 2. Better filtering and breaking down techniques Another technique is to filter out the tiny particles found in water or break them down into harmless fragments. Organic chemistry is providing latest ways in microplastic pollution. Although, chemists are working hard on the development of Photocatalysis. These materials are generally inactive. However, when exposed to sunlight, a chemical reaction starts. This reaction breaks down harmful substances like microplastics present in water or air into less harmful substances. Another method is enzymatic degradation, where small proteins called enzymes chew up plastics as if they were snacks. Scientists performed an experiment to check the ability of catalysts. In this experiment, polluted water was used, and a specific catalyst was added to it. The result of this experiment was astonishing, as the catalyst managed to remove 90% of the microplastics. This was really a remarkable outcome, right? 3. Detection and Monitoring Innovations Before eliminating anything, it is essential to find it first and then understand it thoroughly. Organic chemistry is helping us in this situation as well. Scientists use fluorescence based tagging, where glowing dyes are added to microplastics. When these tagged particles are observed under the microscope, they light up. Another very important technique is spectroscopy, it analyzes the molecular structure of plastics. This method even helps us to pinpoint the specific type of these tiny particles. Once we analyze where microplastics are hidden, it becomes easier to devise strategies to stop them. Want to see these ideas in action? Let’s take a look at real world applications.
