Fabrication of high-performance cell-imprinted polymers based on AuNPs/MXene composites via metal-free visible light-induced ATRP

Abstract

Cell-imprinted polymers for yeasts were fabricated via metal-free visible-light-induced atom transfer radical polymerization on the surface of a glassy carbon electrode which had been modified with gold nanoparticles/MXene (Ti3C2Tx) composites.

Recent advances using MXenes in biomedical applications

“…195 Electrochemical sensors for microorganisms using MXene-based nanomaterials are summarized in Table 4. Exosomes, [196][197][198][199] bacteria, [200][201][202][203][204][205] viruses, 149,[206][207][208][209] and even cancer cells 114,171 can be measured through appropriate surface modification of electrodes. The lowest sensing range is about 10 particles per mL.…”

An ultrasensitive electrochemical sensor for phospholipase C via signal amplification based on breathing ATRP and its application

“…ATRP is typically performed in anaerobic environments because propagating radicals react with oxygen to form stable peroxy radicals and hydroperoxides, thus quenching chain growth. [20][21][22] Moreover, some ATRP methods use low-valence transition metal (such as Cu(I), Fe(II) and Ni(II)) complexes as catalysts, which are sensitive to O 2 . 23 Freeze-pump-thaw cycles, purging with inert gas, and working in a glovebox or Schlenk tube are the commonly used techniques to overcome the effect of oxygen for ATRP systems.…”
