Preparation and specific adsorption of dual antibacterial BSA surface
imprinted GO-PEI/MXene wrinkled microspheres
Abstract
Molecular imprinting technology has gained increasing attention and
application in protein adsorption and separation. Bacterial growth on
the imprinted material would reduce the adsorption selectivity of the
imprinted cavity, contaminate the isolation products and shorten the
service life of the material. To solve the above problems, carrier
materials with dual antibacterial ability are constructed for the first
time and novel surface protein imprinted microspheres
(GO-PEI/MXene@MIPs) are manufactured. Thanks to the large exterior
surface area, the saturation adsorption amount of GO-PEI/MXene@MIPs
reaches 312.63 mg/g with an imprinting factor (IF) value of 3.16 within
90 min. Meanwhile, this imprinted material also exhibits a high ability
to separate real samples as well as reusability. In addition, this
material has excellent broad-spectrum antibacterial effects, which will
significantly extend its service life in real-world environments. This
study provides a feasible solution for the application of surface
protein imprinted materials in real-world environments.
