Nanomedicines have achieved several breakthroughs in cancer treatment over the past decades; however, their potential immunotoxicities are ignored, which results serious adverse effects and greatly reduces clinical translation. Herein, we innovatively develop a theranostic supramolecular polymer using β-cyclodextrin as host camptothecin (CPT) guest linked by glutathione-cleavable disulfide bond. The polymerization remarkably increases solubility of CPT factor 232 effectively inhibits its...

Highly uniform GaAs/GaAsP coaxial nanowires were prepared via selective-area metal organic vapor phase epitaxy. Photoluminescence spectra from a single nanowire indicate that the obtained heterostructures can produce near-infrared (NIR) lasing under pulsed light excitation. The end facets of form natural mirror surface to create an axial cavity, which realizes resonance and give stimulated emission. This study is considerable advance toward realization nanowire-based NIR sources.
In order to promote the development of photodynamic therapy (PDT), undesired side effects like low tumor specificity and "always-on" phenomenon should be avoided.

Single structure characterization shows that two P5 molecules act as supramolecular nanocapsule for one isolated DASP molecule. This spatial confinement effectively restricts aggregation-caused quenching (ACQ) effects other nonradiative channels (e.g., twisted intramolecular charge transfer), leading to high...
