“…Within those inorganic solid supports investigated for designing organic-inorganic hybrids, silica-based mesoporous materials have received increasing attention owing to their good physicochemical stability, satisfactory adsorption efficiency and high reusability [14,15]. And as one of the mesoporous silica materials, SBA-15, which consists of parallel cylindrical pores with axes arranged in a hexagonal unit cell, has been universally reported as a good solid support for designing general purpose adsorbents.…”

“…Chitosan (CS) was a functional biopolymer containing a set of unique characteristics including hydrophilicity, nontoxicity, biocompatibility, physiological inertness and gel forming property. In addition, the effectiveness of high concentration of amino groups in the polyaminoglucosan chains endows the material with excellent functionality for chemical modification [2][3][4][5] . Though CS was viewed as one of the most promising materials for the construction of biosensors, its inherent drawbacks, e.g., swelling and solubility in acidic conditions, must be overcome [5] .…”

Horseradish peroxidase (HRP) and glucose oxidase (GOD) bienzyme biosensor was constructed byin-situ formation of the organic-inorganic biocomposite film based on the one-step electrodeposition and covalent-coupled sol-gel process. The electrodeposition was performed in the solution containing functional inorganic precursor possessing the epoxy groups, γ-glycidoxypropyltrimethoxysiloxane (GPTMS), a biopolymer chitosan (CS), HRP and GOD. The covalent-coupled sol-gel process was formed by self-hydrolysis and self-condensation of GPTMS, followed by in-situ covalent cross-linking of CS, HRP and GOD through covalent reaction between amino groups and epoxy groups. The developed bienzyme biosensor presented high stability in acidic solution owing to the covalent-coupled organic-inorganic hybridization. Compared with the non-hybrid HRP-GOD/CS/Au electrode, the bienzyme biosensor of HRP-GOD/GPTMS/CS/Au showed improved sensitivity and a wider linearrange for the determination of glucose. The linear response of the developed HRP-GOD/GPTMS/ CS/Au biosensor for the determination of glucose ranged from 1 to 351 μmol/L with a detection limit of 0.3 μmol/L. chitosan, GPTMS, glucose, biosensor

“…When removing the template molecule, molecularly imprinted polymers (MIPs) are capable of recognizing and rebinding the desired molecular target with a high selectivity and affinity. The surface molecular imprinting technique is a promising molecular imprinting type, which shows many advantages, including high selectivity, more accessible sites, faster mass transfer and binding kinetics [14][15][16][17][18][19][20][21], for imprinted polymers prepared by this technique, avoiding high embedment and retaining a better site accessibility to the templates.…”

Molecularly imprinted polymers (MIPs) for selective removal of ciprofloxacin (CIP) was prepared by a surface imprinting technique. The MIPs was characterized by Fourier transform infrared spectroscopy and scanning electron microscopy (SEM). The selectivity of the sorbent was investigated by a batch competitive binding experiment using aqueous CIP and gatifloxacin, CIP and chloramphenicol, and CIP and tetracycline mixtures, respectively. The static uptake capacity and selectivity coefficient of the MIPs are higher than those of the non-imprinted sorbent. The imprinted functionalized sorbent offered a fast kinetics for the extraction of CIP, which was obtained within 12 min. In a test of five extraction cycles, the adsorption capacity of the sorbent was above 92% of that of the fresh sorbent. Experimental results showed the potential of MIPs for selectivity removal of CIP.
