DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Enhanced Near-Infrared-Excitable Organic Afterglow Nanoparticles for Deep-Tissue Multimodal Imaging via Singlet Oxygen-Mediated Energy Transfer

Research
Afterglow imaging offers exceptional signal-to-background ratios (SBRs) by circumventing real-time excitation and autofluorescence, yet conventional systems rely on visible-light excitation, limiting tissue penetration and signal intensity.
