A number of alternative approaches involving immunoassays coupled to flow-injection analysis and electrochemical detection have been evaluated with the aim of developing a simple, rapid field-based method for the quantification of gentamicin in milk to within regulatory guide-line levels. Anti-gentamicin antibodies were adsorbed onto nitrocellulose and polycarbonate solid-phase supports and positioned...
An ultra-highly sensitive electrochemical immunosensor for SirT1 (a key protein in age-related diseases) evaluation has been designed, employing polymeric nanocomposites as sensing platform and core-shell SiO2@Au to immobilize HRP-Ab2 as nanobioprobes. The approach includes chemical synthesis of PAMAM-Au-MWCNT nanocomposites (PNCs) with abundant PAMAM-Au nanoparticles immobilized on the MWCNT matrix,...
