Chemosensors for Viruses Based on Artificial Immunoglobulin Copies

“Plastic replicas” of natural antibodies are accessible by molecular imprinting procedures. The first step involves the synthesis of molecularly imprinted polymer (MIP) particles templated with human immunoglobulin. They then can be utilized as templates for a stamp-based surface imprinting procedure that results in polymer surface structures exactly mimicking the initial globulin. Compared to their natural counterparts, these artificial antibodies show improved selectivity and sensitivity on quartz crystal microbalance sensors.
