DOI: 10.1007/s11356-017-9362-1
Abstract: Surface-modified diatom substrates are employed for the development of immunocomplex-based optical biosensor for diagnosis of typhoid. Biosensor has been prepared by covalent immobilization of Salmonella typhi antibody onto the crosslinked diatom substrates via glutaraldehyde. Photoluminescent… read more here.
