Paper Abstract

Direct Laser Interference Patterning (DLIP) technique were employed in the development of optical biosensors based on Biophotonic Sensing Cells (BICELLs). Fabrication was carried out by laser patterning of cross-linked SU-8 thin films deposited both on silicon (Si) and glass substrates. Different photonic structures were developed in order to prove their biosensing suitability by mean of and indirect immunoassay of Bovine Serum Albumin (BSA)/anti-BSA, demonstrating that patterned areas improve the sensitivity in comparison with non-patterned sensing surfaces.
