SOMOphilic alkyne vs radical-polar crossover approaches: The full story of the azido-alkynylation of alkenes

open access: yesBeilstein Journal of Organic Chemistry
We report the detailed background for the discovery and development of the synthesis of homopropargylic azides by the azido-alkynylation of alkenes. Initially, a strategy involving SOMOphilic alkynes was adopted, but only resulted in a 29% yield of the ...

Development of f‐ELISA Sensors with Ultrahigh Sensitivity for On‐Site Colorimetric Detection of Fentanyl and Norfentanyl

open access: yesAdvanced Sensor Research, EarlyView.
A foam‐based ELISA (f‐ELISA) platform was developed using chemically modified melamine foam to enable rapid, ultrasensitive, and selective colorimetric detection of fentanyl and norfentanyl. Abstract Rapid and accurate detection of fentanyl in unknown products and aqueous samples can find the unexpected existence of the toxic chemical and assist law ...

A Polyoxometalate—Carbon Nanotube Enhanced Electrochemical Sensor for Aptamer‐Based Diagnostics

open access: yesAdvanced Sensor Research, EarlyView.
The high electroactive surface area of multi‐walled carbon nanotubes decorated with aptamer‐functionalized polyoxovanadate units enables a ≈1000‐fold increase in peak current response for a model diclofenac detection in aqueous solution compared to unmodified platinum microelectrodes.

Hemp Proteins Conjugated with Green Tea Polyphenol Extract Form De Novo Plant‐Sourced Emulsifiers Suitable for Nanodelivery Systems Bearing Lipophilic Psychopharmaceuticals

open access: yesAdvanced Therapeutics, EarlyView.
Green tea polyphenols, conjugated either covalently or non‐covalently to hemp protein, comprise an excellent stabilizing matrix for oxidatively‐sensitive small molecules. These nanoemulsions are highly stable to a variety of chemical and physical stressors, protecting the small molecule while allowing for easy uptake across cell membranes and rapid ...

The GLP1R Agonist Semaglutide Inhibits Reactive Astrocytes and Enhances the Efficacy of Neural Stem Cell Transplantation Therapy in Parkinson's Disease Mice

open access: yesAdvanced Science, EarlyView.
Compared to transplantation of neural stem cells (NSCs) alone, the combined treatment of NSCs with semaglutide more effectively improves motor dysfunction in Parkinson's disease (PD) mice. This synergistic effect may result from semaglutide's ability to suppress microglial activation, thereby preventing the transformation of resting astrocytes into ...
