Abstract

The healthcare industry is moving towards personalized medicine and patients seek greater role in their care. In this paper we describe a proof of concept of versatile optical sensor that potentially can be used for in vivo detection of biological events. The developed sensor comprises of a silver thin film glass slide and gold nanoparticles (GNPs) and allows detection of chemical changes using surface plasmon resonance (SPR), local surface plasmon resonance (LSPR) and fluorescence lifetime detection modalities. A change in spectrum was observed after removal of GNPs by 2-mercaptoethanol. Moreover, GNP conjugated to fluorescein were tested using fluorescence lifetime microscopy (FLIM) to enhance sensing capabilities and provide additional dimension for detection. The sensor has the potential to provide real-time analyses of different biological molecules, such as antibody and antigen, receptor and ligand, and complementary DNA fragments.
