what is biosensor?

 What is biosensor? A biosensor is a device that uses a biological component (such as enzymes, antibodies, or DNA) to detect and measure specific molecules or compounds in a sample. Biosensors have a wide range of applications in medicine, environmental monitoring, and industrial processes, among others. One of the most common types of biosensors is the enzyme-based biosensor. These biosensors use enzymes as the biological component to detect and measure specific molecules in a sample. For example, glucose biosensors use enzymes that specifically catalyze the oxidation of glucose, and the resulting electrical signal can be used to measure the glucose concentration in a sample. Enzyme-based biosensors are commonly used in medical applications, such as monitoring glucose levels in people with diabetes. Another type of biosensor is the antibody-based biosensor. These biosensors use antibodies as the biological component to detect and measure specific molecules in a sample. Antibodies ...

CT or computed tomography explained

 CT or computed tomography explained Computed Tomography (CT) is a medical imaging technique that uses X-rays and computer technology to create detailed cross-sectional images of internal organs, bones, and other tissues. CT scans are often used to diagnose diseases and injuries, and to monitor the progression of treatment. The basic concept of CT is to take a series of X-ray images from different angles around the body and then use a computer to combine them into a detailed 3D image. CT scans work by using X-ray beams to penetrate the body and create an image of the internal structures. The X-ray beam is emitted from a circular tube called an X-ray source and is directed at the body part being scanned. The X-ray beam passes through the body and is detected by an array of detectors on the opposite side. The CT scanner takes multiple X-ray images, each at a slightly different angle, while the patient is moved through the machine. The computer then combines these images to create a d...

What is electrocardiography? how to diagnose?

 What is electrocardiography? how to diagnose?  Electrocardiography (ECG or EKG) is a diagnostic test that records the electrical activity of the heart. The test is used to evaluate the heart's electrical activity and rhythm, and to diagnose and evaluate conditions such as heart attacks, arrhythmias, and heart disease. ECG test is performed by attaching electrodes to the skin of the chest, arms, and legs. The electrodes are connected to an ECG machine, which records the electrical activity of the heart. The test is usually done while the patient is lying down, and it takes about 5-10 minutes to complete. The ECG tracing, which is a graph of the heart's electrical activity, is analyzed by a healthcare professional. The tracing shows the electrical activity of the heart as it goes through its normal cycle of contraction and relaxation. The healthcare professional can use this information to diagnose and evaluate conditions such as: Heart attacks: A heart attack occurs when the b...
