The
search for novel fluorescent materials has attracted the attention
of many researchers. Numerous bioimaging materials based on the aggregation-induced
emission (AIE) units have been surging and could be employed in wide
areas during the past two decades. In recent few years, the appearance
of nonconventional fluorescence emitters without aromatic conjugated
structures provides another bioimaging candidate which has the advantage
of enhanced biodegradability and relatively low cost, and their luminescent
mechanism can be explained by clustering-triggered emission (CTE)
like AIE. In our contribution, we utilize nonaromatic sugar as a monomer
to prepare a series of glycopolymers with designed components through
sunlight-induced reversible addition fragmentation chain transfer
polymerization; these glycopolymers can be employed in bioimaging
fields due to the bioactivity coming from sugar and CTE capacity.
Surface-enhanced Raman scattering (SERS), which is based on the surface plasmons resonance (LSPR) of noble metal nanostructures, is widely used in biological field due to its advantages of non-damaging samples...
Photopolymerization is attracting great attention due to its advantages such as low cost and spatiotemporal control. Broadband photopolymerization is attractive than ultraviolet polymerization, which is of special significance for better...
We successfully synthesized glyco-micromotors in situ directed by multifunctional glycopolymers. The fabricated glyco-micormotor presents abilities in loading and guiding bacteria with different individual and group motions.
Introducing aggregation‐induced emission luminogens (AIEgens) to fluorescence sensors will endow them with outstanding luminescence properties in aggregated state or solid state, which is an effective strategy for developing polymer‐based fluorescence sensors. Herein, a novel fluorescence sensor of TPE‐A‐MIPs was developed by introducing an AIEgen as the fluorescence signal part into molecularly imprinted polymers (MIPs). MIPs in this sensor served as a polymeric artificial receptor to Rhodamine B (RhB), which offered high selectivity. TPE‐A‐MIPs also showed excellent sensitivity with ratiometric fluorescence response to RhB. A detection limit of 1.41 μmol/L with the linear range in 0.0‐10.0 μmol/L was obtained. Furthermore, TPE‐A‐MIPs was successfully applied in detecting RhB in real food samples with satisfactory recoveries and relative standard deviations. This work not only demonstrated the feasibility of introducing AIEgens into MIPs to develop fluorescence sensors, but also greatly expanded the potential applications of AIEgens and MIPs in the field of fluorescence detection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
