The simple variant of Carboxybetaine terminated SAM 

was successfully used to immobilise lectins and construct non fouling sensor aiming glycoprofiling of antibodies isolated from healthy individuals and rhematoid arthritis patients. Our team has further develop the AuNPs functionalised with zwitterionic ligands for production of hyperstable biocompatible colloidal gold.
