Abstract

The present invention relates to an optical biosensor comprising of an etched fiber Bragg grating (eFBG), having a plurality of coatings comprising of: (a) nano carbon materials and (b) one or more dendrimer molecule(s), wherein the nano carbon materials are attached with one or more dendrimer molecule(s) and coated onto surface of the eFBG. The optical biosensor of the present invention is highly sensitive in detection of antigen-antibody and carbohydrate-protein interactions. A method of fabrication of the optical biosensor is also provided.
