Getting a medication to the right place in the body is often more difficult than simply developing the drug itself. Conventional drug-delivery systems, including nanoparticles, can face challenges such as limited targeting and rapid removal from the body. Researchers are exploring a different approach: using living cells as therapeutic delivery vehicles. Rather than acting as passive containers, these cells can naturally interact with their surroundings, remain in circulation

HbA1c measures the percentage of sugar coated on hemoglobin, acting as a "metabolic memory" of your blood sugar over the last 2–3 months. Unlike daily finger-pricks, it provides a long-term view of your health. Understanding this number is vital for diagnosing diabetes and preventing complications like heart or kidney disease. It is the gold standard for tracking treatment success and maintaining long-term wellness.
