Inorganic nanomaterials that have inherently exceptional physicochemical properties (e.g., catalytic, optical, thermal, electrical, or magnetic performance) can provide desirable functionality drug delivery, diagnostics, imaging, therapy) considerable potential for application in the field of biomedicine. However, toxicity be caused by long-term, non-specific accumulation these inorganic healthy tissues, preventing their large-scale clinical utilization. Over past several decades, emergence biodegradable and clearable has offered to prevent such long-term toxicity. In addition, a comprehensive understanding design metabolic pathways within body is essential enabling expansion theranostic applications various diseases advancing trials.

Two-dimensional molecular brush-functionalized porous bilayer composite separators toward ultrastable high-current density lithium metal anodes

Nature Communications, Journal Year: 2019, Volume and Issue: 10(1)

Published: March 25, 2019

Abstract Lithium metal batteries have been considerably limited by the problems of uncontrolled dendritic lithium formation and highly reactive nature with electrolytes. Herein, we developed functional porous bilayer composite separators simply blade-coating polyacrylamide-grafted graphene oxide molecular brushes onto commercial polypropylene separators. Our integrate lithiophilic feature hairy polyacrylamide chains fast electrolyte diffusion pathways excellent mechanical strength nanosheets thus enable molecular-level homogeneous ionic flux on surfaces electrodes. As a result, dendrite-free uniform deposition high Coulombic efficiency (98%) ultralong-term reversible plating/stripping (over 2600 h) at current density (2 mA cm −2 ) are achieved for anodes. Remarkably, anodes an unprecedented stability more than 1900 h cycling ultrahigh 20 demonstrated.

Glutathione-Depleting Nanomedicines for Synergistic Cancer Therapy

ACS Nano, Journal Year: 2021, Volume and Issue: 15(5), P. 8039 - 8068

Published: May 11, 2021

Cancer cells frequently exhibit resistance to various molecular and nanoscale drugs, which inevitably affects the drugs' therapeutic outcomes. Overexpression of glutathione (GSH) has been observed in many cancer cells, solid evidence corroborated resulting tumor a variety anticancer therapies, suggesting that this biochemical characteristic can be developed as potential target for treatments. The single treatment GSH-depleting agents potentiate responses different cell death stimuli; therefore, an adjunctive strategy, GSH depletion is usually combined with mainstream therapies enhancing Propelled by rapid development nanotechnology, readily constructed into nanomedicines, have shown steep rise over past decade. Here, we review common nanomedicines widely applied synergistic treatments recent years. Some current challenges future perspectives depletion-based are also presented. With understanding structure–property relationship action mechanisms these biomaterials, hope nanotechnology will further realize more effective disease even achieve successful clinical translations.
