The molecularly imprinted polymers (MIP) were prepared via aqueous RAFT precipitation polymerization, with aristolochic acid I (AAI) as the template molecule, AA as the functional monomer, EGDMA as the cross-linker, AIBN as the chain initiator, CTP as the chain transfer agent and 80% (g/g) DMF-aqueous solution as the porogen. The differential UV–vis spectra revealed that a cooperative hydrogen-bonding...
A new rhodamine B–benzofurazan based fluorescent probe (1) for Fe3+ and Hg2+ was synthesized. In aqueous solution containing 30% (v/v) ethanol, probe 1 shows a high selective fluorescent enhancement recognition to Fe3+ with a binding ratio of 1:1 (probe 1: Fe3+), when the concentration of Fe3+ is less than that of the probe. When the concentration of Fe3+ is higher than that of the probe, it shows...
A new single-isomer cationic cyclodextrin, mono-6 A -[3-(3-methoxypropyl)imidazol-1-ium]-6 A -β-cyclodextrin chloride, has been synthesized and successfully used for the chiral separation of dansyl amino acids in capillary electrophoresis. With methoxy functionality, the new cationic cyclodextrin exhibits significantly improved enantioselectivities. Excellent enantioseparations for...
A highly sensitive electrochemical immunosensor based on combination of chitosan (CHIT) and coral-shaped AuNPs (C-AuNPs) to form an immobilization matrix has been developed using human IgG as a model analyte. The inorganic–organic hybrid film with abundant adsorbing sites and large surface area can reserve the biocompatibility of the biomaterials which greatly increase loading amounts of assembling,...
Nickel hexacyanoferrate film modified gold electrode was prepared by a simple chemical deposition procedure from a fresh prepared solution containing ferricyanide, Ni 2+ , and sodium nitrate. The resultant films have solo composition and are significantly stable as compared to the electrochemically deposited NiHCF films. For different concentrations of Na + in the solution, the formal...
