A new breakthrough in biotechnology is set to revolutionize how we detect and treat diseases. Scientists have developed a hydrogel-based material that is capable of binding to a target molecule with high specificity, similar to an antibody. This material, known as an aptamer, is made of a strand of DNA or RNA, and has the potential to be used as a chemical antibody, allowing for the detection of diseases and toxins in a much faster and more accurate way than traditional methods. This could be a game-changer in medical diagnosis and treatment, and has implications for the future of biotechnology.
