Synthetic antibodies represent a burgeoning field in biotechnology, characterized by the design and production of antibody mimics that can be generated entirely in vitro. This eliminates the need for animal-derived antibodies, thus paving the way for more ethical, sustainable, and possibly more effective therapeutic and diagnostic tools. Synthetic antibodies encompass a broad spectrum of technologies, including recombinant antibodies, nucleic acid aptamers, and non-immunoglobulin protein scaffolds, which can be engineered for high affinity and specificity to virtually any desired antigen.
