A dual-color fluorescent biosensing platform based on amine functionalized 3D copper Prussian blue nanocubes and exonuclease I activity for simultaneous detection of kanamycin and streptomycin

“…Multicolour fluorescence detection is the most efficient method for detecting multiple biomolecules. [14][15][16] FRET is a method wherein energy is transferred between fluorescence elements (various fluorophores, carbon quantum dots, and up conversion nanoparticles, for example) as donors and quenching materials (metal oxides, graphene oxide, MoS 2 and various MOFs, [17][18][19] for example) as acceptors. Whenever the distance between the donor and acceptor is less than 10 nm, the fluorescence could be quenched due to the overlapping of the energy donor's emission spectrum and the energy acceptor's absorption spectrum.…”

A reusable fiber-embedded microfluidic chip for rapid and sensitive on-site detection of kanamycin residues in water environments

“…Microfluidic chips allow for the manipulation and flexible design of microfluids and have emerged as a powerful platform for antibiotic detection. [9][10][11][12] In particular, the advancement of optical microfluidic chips has significantly accelerated the on-site detection of antibiotics in environmental water samples because of their sensitivity, miniaturization, and electromagnetic-free interference. [9][10][11][12] Nevertheless, traditional optical microfluidic chips are still in their nascent stages of progress, and their limitations in terms of on-site detection are primarily demonstrated by the following aspects.…”
