Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy

Advanced Functional Materials, EarlyView.
In this study, we report producing spherical MXenes via fs laser fragmentation of Ti3C2 flakes in liquid medium. The nanoparticles demonstrated pronounced light absorption and high photothermal conversion efficiencies of 68% and 63% under heating with NIR‐I and NIR‐II lasers, respectively.

A Review on the Application of Fluorescence Sensors Based on Fluorescence Resonance Energy Transfer Effect for Mycotoxins Detection [PDF]

Shipin Kexue
Mycotoxins are highly toxic and carcinogenic to humans and animals, and mycotoxin pollution in foods is difficult to prevent and control, which has sparked increasing concern. Therefore, it is necessary to detect mycotoxins in foods.

Drug transport mechanism of P-glycoprotein monitored by single molecule fluorescence resonance energy transfer

, 2011
In this work we monitor the catalytic mechanism of P-glycoprotein (Pgp) using single-molecule fluorescence resonance energy transfer (FRET). Pgp, a member of the ATP binding cassette family of transport proteins, is found in the plasma membrane of animal

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

Advanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Absence of clustering of phosphatidylinositol-(4,5)-bisphosphate in fluid phosphatidylcholine

Journal of Lipid Research, 2006
Phosphatidylinositol-(4,5)-bisphosphate [PI(4,5)P2] plays a key role in the modulation of actin polymerization and vesicle trafficking. These processes seem to depend on the enrichment of PI(4,5)P2 in plasma membrane domains. Here, we show that PI(4,5)P2
