With the progress of atherosclerosis (AS), the arterial lumen stenosis and compact plaque structure, the thickening intima and the narrow gaps between endothelial cells significantly limit the penetration efficiency of nanoprobe to plaque, weakening the imaging sensitivity and therapy efficiency. Thus, in this study, a HO-NIR dual-mode nanomotor, Gd-doped mesoporous carbon nanoparticles/Pt with rapamycin (RAPA) loading and AntiCD36 modification (Gd-MCNs/Pt-RAPA-AC) was constructed. The asymmetric deposition of Pt on Gd-MCNs catalyzed HO at the inflammatory site to produce O, which could promote the self-motion of the nanomotor and ease inflammation microenvironment of AS plaque.

Background/aims: To identify the risk factors for neuropathic corneal pain (NCP) following corneal refractive surgery and to report its clinical manifestations, imaging and proteomic characteristics.
Methods: This 1 year prospective cohort study included 100 eyes that underwent small incision lenticule extraction (SMILE) or laser-assisted in situ keratomileusis (LASIK). Ocular surface assessments, in-vivo confocal microscopy scans, tear neuromediators and proteomics analyses were performed.

The secondary near-infrared region (NIR-II) fluorescence imaging-guided photothermal therapy (PTT) offers a noninvasive and light-controllable treatment option for deep-seated cancers. However, the development of NIR-II photothermal agents (NIR-II PTAs) that possess the desired properties of high molar absorption coefficient (ε), fluorescence quantum yield (QY), and photothermal conversion efficiency (PCE) remain a challenge due to the contradiction between radiative and nonradiative processes. Herein, we propose a novel side-chain heteroatom substitution engineering strategy to simultaneously enhance ε, QY, and PCE by modifying the molecular planarity.

Despite phthalocyanine has excellent photodynamic and photothermal effects as a photosensitizer and photothermal agent, hydrophobicity and aggregation limits its biological application. In this paper, phthalocyanine-cyanine co-assembled nanoparticles were designed to modulate the dimensions and morphology by introducing water-soluble cyanine. The cyanine had the ability to transform the nanomaterials from microrods to nanospheres, thus successfully constructing photoactivated nanomedicines.
