Fabrication of glucose-sensitive TiO2 ultrathin films by molecular imprinting and selective detection of monosaccharides

Biosensing Applications of Molecularly Imprinted Nanomaterials

“…When used in a flow-injection analysis system, the assembled QCM sensor generated a large frequency change upon encountering a small amount of analyte (0.19 mM), had a very short response time (<1 min), and displayed certain chiral selectivity toward the original template, S-propranolol, at a concentration higher than 0.38 mM. Yang et al [141] fabricated an MIP-based QCM using the glucose-sensitive TiO 2 ultrathin composite films as recognition element for the detection of monosaccharides. The largest binding capacity was 2.3-fold more than that of the corresponding nonimprinted films.…”

Inorganic Molecularly Imprinted Polymer by Sol-Gel Process for Recognition of Caffeine

“…This technique is a very useful approach for the fabrication of a matrix with molecular recognition sites that are formed by the addition of template molecules during the matrix formation process, and for the removal of the template molecule after the matrix formation [1][2][3][4][5]. Molecularly imprinted matrixes have been developed for over a decade in many fields, such as chromatography, catalysis, artificial antibodies, and sensing devices [6][7][8][9][10][11][12].…”

Enhanced removal of bilirubin on molecularly imprinted titania film

“…Recently, inorganic matrices have been employed for molecular imprinting. Compared with molecularly imprinted organic polymer, molecularly imprinted inorganic matrices not only possessed a better stability and structural rigidity, but relieved some drawbacks of organic material such as low binding efficiency, slow binding process, and difficult fabrication [23][24][25]. Silica and titania sol-gel materials have been used to prepare molecularly imprinted thin film, which was used for the determination and separation of organism [26,27].…”
