A novel imprinting scheme, combining for the first time electropolymerization with metal-ion coordination, has been proposed. A MIP for a pesticide (4-(2,4-dichlorophenoxy)butyric acid (2,4-DB)) has been prepared from a Co-porphyrin (Co(III)tetrakis(o-aminophenyl) porphyrin (CoTAPP)) as functional monomer. Such an approach aims to combine advantages of electropolymerization with ones related to the...
The “grafting from” synthesis of core-shell molecularly imprinted polymer nanoparticles (Ser-MIP@SiO2 NPs) has been applied to the development of an electrochemical sensor for Serotonin. Ser-MIP@SiO2 NPs have been synthesized on preformed SiO2 nanobeads by surface imprinting via reversible additionfragmentation chaintransfer (RAFT) polymerization. After polymerization, the reductive aminolysis of...
Preliminary results on detection of neurotransmitter serotonin using an electrochemical sensor, based on a composite made of core-shell molecularly imprinted polymer (MIP) nanoparticles and polyethylenedioxythiophene (PEDOT) film are described. MIP is grown on pre-formed SiO2 nanobeads by surface imprinting via reversible addition-fragmentation chain-transfer (RAFT) polymerization. The core-shell...
Light-activated electropolymerization on micromachined n-type silicon is here demonstrated to be a versatile route for microstructuring conducting polymers (CPs) and CP-based Molecularly Imprinted Polymers (MIPs). Several CPs — namely polypyrrole (PPy), poly(3,4-ethylendioxythiophene) (PEDOT), poly(3-methylthiophene) (P3MT), polythiophene (PT) — and a PPy-based MIP have been deposited on different...
