Selective POF sensors based on surface plasmon resonance exploiting aptamers, MIPs and antibodies as receptors

A simple approach to low-cost plasmonic sensing has been obtained with a specific multilayer deposited on a D-shaped Plastic Optical Fiber (POF). When receptors are used for Bio/Chemicals detection, this low cost sensing platform can be exploited in different fields: industrial applications, medical diagnostics, environmental monitoring, food safety and security. The experimental setup, used in these applications, is lowcost and very easy to use. In the last years, we have explored very important applications, with fine experimental results, different kinds of receptors combined with the same POF platform, as Molecularly Imprinted Polymers (MIPs) and Bio-receptors.
