These Nanofitins® are potent antibody-mimetics that have a high affinity and specificity for capturing and targeting biomolecules. They are 20 times smaller than antibodies and demonstrate hyper stability. Nanofitins® can be easily combined with each other, antibodies, and other biomolecules using simple and rapid methods to design targeted molecules. Affilogic has designed Nanofitins® against over 60 targets, including circulating antigens, membrane receptors, and complex entities such as virus-like particles and bacteria. Their innovative approach offers a robust and affordable alternative to antibodies in the field of biotechnology.
