- 1. Biomaterials are materials that are designed to interact with biological systems for medical purposes, such as tissue repair, drug delivery, and medical implants. These materials can be natural or synthetic and are carefully engineered to have specific properties that promote compatibility with the body. Biomaterials need to be biocompatible, non-toxic, and able to integrate with living tissues without causing adverse reactions. They play a crucial role in advancing healthcare by enabling treatments that would not otherwise be possible. Researchers continue to explore new biomaterials and improve existing ones to further enhance their performance and applications in the medical field.
