“…MY was used as support of a MIP-based material for the selective adsorption of SMX. Compared to other support materials such as SiO 2, carbon nanotubes, or Fe 3 O 4 -SiO 2 used in the literature [ 36 , 37 ], MY particles can act as support without the need of an intermediate chemical modification step and can distinctly improve grafting efficiency.…”

In this work, magnetic yeast (MY) was produced through an in situ one-step method. Then, MY was used as the core and the antibiotic sulfamethoxazole (SMX) as the template to produce highly selective magnetic yeast-molecularly imprinted polymers (MY@MIPs). The physicochemical properties of MY@MIPs were assessed by Fourier-transform infrared spectroscopy (FT-IR), a vibrating sample magnetometer (VSM), X-ray diffraction (XRD), thermogravimetric analysis (TGA), specific surface area (SBET) determination, and scanning electron microscopy (SEM). Batch adsorption experiments were carried out to compare MY@MIPs with MY and MY@NIPs (magnetic yeast-molecularly imprinted polymers without template), with MY@MIPs showing a better performance in the removal of SMX from water. Adsorption of SMX onto MY@MIPs was described by the pseudo-second-order kinetic model and the Langmuir isotherm, with maximum adsorption capacities of 77 and 24 mg g−1 from ultrapure and wastewater, respectively. Furthermore, MY@MIPs displayed a highly selective adsorption toward SMX in the presence of other pharmaceuticals, namely diclofenac (DCF) and carbamazepine (CBZ). Finally, regeneration experiments showed that SMX adsorption decreased 21 and 34% after the first and second regeneration cycles, respectively. This work demonstrates that MY@MIPs are promising sorbent materials for the selective removal of SMX from wastewater.

“…It is obvious that one can make good MIPs with high efficiency in binding target molecules or fragments thereof. Based on the observations from affinity chromatography, one can foresee that such systems will also soon be presented for capacitive biosensors [42,43,44,45,46,47,48] (Table 2). …”

Abstract:Capacitive biosensors belong to the group of affinity biosensors that operate by registering direct binding between the sensor surface and the target molecule. This type of biosensors measures the changes in dielectric properties and/or thickness of the dielectric layer at the electrolyte/electrode interface. Capacitive biosensors have so far been successfully used for detection of proteins, nucleotides, heavy metals, saccharides, small organic molecules and microbial cells. In recent years, the microcontact imprinting method has been used to create very sensitive and selective biorecognition cavities on surfaces of capacitive electrodes. This chapter summarizes the principle and different applications of capacitive biosensors with an emphasis on microcontact imprinting method with its recent capacitive biosensor applications.

“…Non-imprinted polymeric (NIP) nanostructures were synthesized by the same method without adding cholesterol into polymerization mixture. Characterization studies such as FTIR analysis, particle size measurement, and scanning electron microscopy (SEM) analysis were performed synthesis and characterization data for MIP with the template:monomer ratio as 1:1 were given in our previous study [35].…”

A B S T R A C TT his study reports cholesterol adsorption from artificial human plasma using MIP nanostructures prepared with different template:monomer ratios. The adsorption capacity of CP is 19.9% and 16.1% higher than those of C3P and CP3, respectively and adsorption capacity of CP is significantly higher than NIP nanostructures. All selectivity coefficients and relative selectivity values were higher than 1 for artificial human plasma. Under optimum conditions, considerably high cholesterol was adsorbed from hypercholesterolemic plasma (95.33 %).
