A Multimode Optical Sensor for Highly Selective and Sensitive Detection of Hypochlorous Acid in Water and Body Fluid.

Hypochlorous acid (HClO), as an important reactive oxygen species (ROS), plays a crucial role in our daily life and in biological systems, and its convenient and accurate detection is significant and imperative. In this work, a self-calibrated multimode optical sensor for convenient and accurate HClO detection was elaborately fabricated based on a multifunctional metal-organic framework platform with catalytic active metal nodes, fluorescent responsive bridging ligands, and intrinsic pores for functional molecule accommodation. The sensor shows not only turn-on and ratiometric fluorescence response but also color change in response to HClO.

A Highly Selective Ammonia Ratiometric Fluorescence Sensor Based on Multifunctional Metal-Organic Framework Platform with Rich Brønsted Acidic Metal Clusters.

Ammonia is a critical chemical in industry and our daily life, but its corrosiveness and toxicity also require enough attention. With the increasing pursuit of beauty, the safety of cosmetics has aroused widespread concern. Aqueous ammonia has been widely used as a universal additive in cosmetics, especially in different types of hair dye products.

A Multimode Optical Sensor for Selective and Sensitive Detection of Harmful Heavy Metal Cr(VI) in Fresh Water and Sea Water.

Water pollution originating from heavy metals has shown great impacts on the ecological environment and human health due to their extremely low biodegradability. Hexavalent chromium Cr(VI), as one harmful heavy metal with strong oxidation, high biological permeability, and high carcinogenicity, is becoming an increasingly serious threat to human health. Therefore, conveniently but accurately, monitoring the Cr(VI) level in water to maintain its normal level and ensuring the stability of the ecosystem and human health become very valuable.

A novel endophytic fungus strain of : its identification, genomic analysis, and effects on plant growth.

Introduction: Endophytic microorganisms are bacteria or fungi that inhabit plant internal tissues contributing to various biological processes of plants. Some endophytic microbes can promote plant growth, which are known as plant growth-promoting endophytes (PGPEs). There has been an increasing interest in isolation and identification of PGPEs for sustainable production of crops.
