Attributes, Fabrication, and Applications of Gallium‐Based Liquid Metal Particles

Advanced Science, Journal Year: 2020, Volume and Issue: 7(12)

Published: April 22, 2020

This work discusses the attributes, fabrication methods, and applications of gallium-based liquid metal particles. Gallium-based metals combine metallic fluidic properties at room temperature. Unlike mercury, which is toxic has a finite vapor pressure, gallium possesses low toxicity effectively zero pressure temperature, makes it amenable to many applications. A variety methods produce particles with variable sizes, ranging from nm mm (which upper limit set by capillary length). The nature enables methods-such as microfluidics sonication-that are not possible solid materials. possess several notable including metal-metal oxide (liquid-solid) core-shell structure well ability self-heal, merge, change shape. They also have unusual phase behavior that depends on size no known commercial applications, but they show promise for drug delivery, soft electronics, microfluidics, catalysis, batteries, energy harvesting, composites. Existing challenges future opportunities discussed herein.

Nanoagent‐Promoted Mild‐Temperature Photothermal Therapy for Cancer Treatment

Advanced Functional Materials, Journal Year: 2021, Volume and Issue: 31(25)

Published: March 31, 2021

Abstract Photothermal therapy (PTT), which utilizes near‐infrared light‐absorbing agents to ablate tumor, has emerged as a highly promising anticancer strategy and received intensive clinical trials in recent years. Mild‐temperature PTT, circumvents the limitations of conventional PTT (e.g., thermoresistance adverse effects), is emerging shows great potential forthcoming applications. However, mild‐temperature without adjuvant not able completely eradicate tumors because its therapeutic efficacy dramatically impaired by inferior heat intensity. As result, strategies capable enhancing are urgently necessitated, mainly rely on on‐demand fabrication functionalized nanoagents. In this review, nanoagent‐promoted highlighted. Furthermore, challenges opportunities field rationally proposed, hopefully people can be encouraged therapy.

A Glucose/Oxygen‐Exhausting Nanoreactor for Starvation‐ and Hypoxia‐Activated Sustainable and Cascade Chemo‐Chemodynamic Therapy

Small, Journal Year: 2020, Volume and Issue: 16(31)

Published: June 15, 2020

Abstract Fenton reaction‐mediated chemodynamic therapy (CDT) can kill cancer cells via the conversion of H 2 O to highly toxic HO•. However, problems such as insufficient levels in tumor tissue and low reaction efficiency severely limit performance CDT. Here, prodrug tirapazamine (TPZ)‐loaded human serum albumin (HSA)–glucose oxidase (GOx) mixture is prepared modified with a metal–polyphenol network composed ferric ions (Fe 3+ ) tannic acid (TA), obtain self‐amplified nanoreactor termed HSA–GOx–TPZ–Fe –TA (HGTFT) for sustainable cascade exogenous production TA‐accelerated Fe /Fe 2+ conversion. The HGTFT efficiently convert oxygen into HO• CDT, consume glucose starvation therapy, provide hypoxic environment TPZ radical‐mediated chemotherapy. Besides, it revealed that significantly elevate intracellular reactive species content hypoxia level, decrease glutathione content, release metal tumors ion interference (also “ion‐interference therapy” or “metal therapy”). Further, also increase tumor’s level inhibit growth. It believed this microenvironment‐regulable anticancer excellent biosafety represents an advance nanomedicine.
