Abstract

In this study, low-cost common electronics components including laser diode, solar-cell and multimeter were employed and reassembled as an optical transducer for the materialization of gold nanoparticle-based immunosensing system. For the versatile biosensing, two types of gold nanoparticles and laser sources were introduced and used. For the simple immunoassay without washing procedures, superparamagnetic microparticles (MPs) were introduced as an immunosensing substrate in the developed optical immunosensing system.
