Multimodal sensing system based on phenylboric acid-COF/RhB ratio fluorescence: highly sensitive detection of ovarian cancer biomarker, smartphone-assisted field analysis and information encryption and anti-counterfeiting integration.

It is essential to develop an innovative technology with high sensitivity and real-time detection for the early diagnosis of ovarian cancer. The cross-disciplinary application of multifunctional materials represents a significant trend in contemporary sensing research. In this paper, a ratio-type fluorescence sensing platform RhB/TFBBPY-COF@PBA was constructed from the covalent organic framework (COF) co-functionalized by phenylboric acid and rhodamine B (RhB).

Construction of an electrochemical sensor based on N-COF@MWCNT-COOH/Tri-AgNPs for sensitive detection of tyrosine in biological fluids.

A sensitive electrochemical sensor was constructed for tyrosine detection by collaborating a highly conductivity, excellent electrocatalysis and large surface of nitrogen-rich porous covalent organic framework in situ grown on three-dimensional conductive carboxylated multi-walled carbon nanotubes network and catalytic activity of triangular silver nanosheets. The prepared electrochemical sensing platform exhibited satisfactory results for detection of tyrosine with a wide linear range of 0.6-280 μM and a low detection limit of 0.

Selective Transformation of Biomass and the Derivatives for Aryl Compounds and Hydrogen via Visible-Light-Induced Radicals.

ConspectusFor sustainable development, exploring renewable resources is an urgent priority. Nonfood biomass, one of the largest renewable resources on Earth, primarily comprises three key components: lignin (ca. 15-30%), cellulose (ca.
