The role of nanotechnology in biological applications: Review article

Abstract

Through the use of unique nano-properties for targeted action and increased sensitivity, such as large surface area and quantum effects. By enabling precise manipulation of matter at the molecular level, nanotechnology revolutionizes biology and leads to advances in tissue engineering (biocompatible implants, 3D bioprinting scaffolds), gene editing, drug delivery (targeted cancer therapy, fewer side effects), and diagnostics (ultra-sensitive biosensors for early disease detection, imaging). Since nanotechnology primarily inhibits and destroys germs, it is a powerful tool against antibiotic resistance.

By using nanosensors to enable early detection, enhanced imaging to improve diagnosis, and targeted drug delivery (nanocarriers like liposomes) to improve treatment. Currently, molecular imaging uses a variety of nanoparticles, and in recent decades, the use of nanoparticles for cancer detection and monitoring has attracted a lot of attention. By facilitating targeted drug delivery, painless oral insulin administration, more intelligent glucose monitoring, and regenerative medicine, going beyond injections to offer glucose-responsive systems.
