Sensor elements based on localized surface plasmon resonance phenomenon in arrays of Au nanostructures on glass substrates (nanochips) with molecularly imprinted acrylamide copolymer coating have been proposed for explosives analogues sensing in liquid and vapor phase. Nanochips exhibited detection limits of 1 pM in aqueous solution and 0.1 ppm in gaseous state against 4-nitrophenol. Vapor phase sensing of 4-nitrotoluene, 1-nitronaphthalene and 5-nitroisoquinoline using the developed 4-nitrophenol-imprinted plasmonic nanochips demonstrated partially selective response with time to signal saturation starting from 2 minutes.

Spr Sensor

Molecularly imprinted polymer-based surface plasmon resonance sensor prepared using silver nanoparticles was designed for the selective recognition of Penicillin G (PEN-G) antibiotic from both aqueous solution and milk sample. PEN-G imprinted sensors (NpMIPs) SPR sensor was fabricated using poly (2-hydroxyethyl methacrylate-N-methacroyl-(L)-cysteine methyl ester)-silver nanoparticles-N-methacryloyl-L-phenylalanine methyl ester polymer by embedding silver nanoparticles (AgNPs) into the polymeric film structure. In addition, a non-imprinted (NpNIPs) SPR sensor was prepared by utilizing the same polymerization recipe without addition of the PEN-G template molecule to evaluate the imprinting effect. FTIR-ATR spectrophotometer, ellipsometer, contact angle measurements were used for the characterization of NpMIPs SPR sensors. The linear concentration range of 0.01–10 ng/mL PEN-G was studied for kinetic analyses. The augmenting effect of AgNPs used to increase the surface plasmon resonance signal response was examined using polymer-based PEN-G imprinted (MIPs) sensor without the addition of AgNPs. The antibiotic amount present in milk chosen as a real sample was measured by spiking PEN-G into the milk. According to the Scatchard, Langmuir, Freundlich and Langmuir–Freundlich adsorption models, the interaction mechanism was estimated to be compatible with the Langmuir model.
