Composite of CdTe quantum dots and molecularly imprinted polymer as a sensing material for cytochrome c

Preparation of Quantum Dots and Fluorescent Molecularly Imprinted Composite Microspheres for Determination of Tyramine

“…MIPs and QDs technology are both polymer materials technology, which have developed over recent decades and are widely used in various fields, including the field of food safety [20] . It has been reported that the MIP-coated CdTe composites integrate the advantages of the high selectivity of the molecular imprinting and strong fluorescence property of the QDs [21] . So the new material combined the advantages of QDs and MIP will play a great role in certain fields of the small-molecule contamination detection.…”

Molecularly imprinted polymer anchored on the surface of denatured bovine serum albumin modified CdTe quantum dots as fluorescent artificial receptor for recognition of target protein

“…After being stirred for 1 h at room temperature, the BSA solution was heated to 60-80 • C in water bath for 20 min to decompose the excess NaBH 4 . The water-soluble CdTe QDs were synthesized based on previous publication (Li et al, 2008;Zhang et al, 2011). The solution of CdTe QDs was mixed with the dBSA solution in proper molar ratios.…”

“…The MIP-based dBSA modified CdTe QDs were prepared via a surface molecular imprinting process similar to a previously reported approach Zhang et al, 2011). The 3-aminopropyltriethoxysilane (APTES) was used as a functional monomer which had a noncovalent interaction with the template protein.…”

“…Therefore, if we combine the high selectivity of molecular imprinting technology and excellent fluorescent characteristics of QDs, a new affinity material, with specific recognition cavity and responding to the binding event with significant fluorescence intensity change, could be prepared. However, considerable interest has been focused on the development of small molecules imprinted polymer coated QDs, producing protein imprinted polymer based QDs was still a challenge (Haupt et al, 1998;Carlson et Li et al, 2010;Lin et al, 2004Lin et al, , 2009Liu et al, 2010;Diltemiz et al, 2008;Wang et al, 2009;Zhang et al, 2011).…”

Smart surface imprinting polymer nanospheres for selective recognition and separation of glycoprotein

“…Especially, surface imprinting over nanosized sphere support materials with large specific surface area, is very appropriate for a template of bulky structure like protein. Many particles have been successfully used as supports in the surface imprinting process, such as silica nanoparticles [16], Fe 3 O 4 magnetic nanoparticles [17], and quantum dots [18]. Nevertheless, the surface functionalization and modification of the above mentioned particles need to be achieved by a complex or multi-step graft polymerization.…”
