In Situ Electrically Resettable Field‐Effect Transistor Biosensors for Continuous and Multiplexed Neurotransmitter Detection

open access: yesAdvanced Science, EarlyView.
The research team integrated a potentiometrically controlled pH electrode with carbon nanotube (CNT) field‐effect transistor (FET) biosensors on a single chip using compatible processes. By employing zonal modification and optimized pH‐sensitive probes, they achieved simultaneous quadruple‐target detection and tenfold reusability under physiological ...

Reactivity of (Bicyclo[5.1.0]octadienyl)iron(1+) Cations: Application to the Synthesis of cis-2-(2’-carboxycyclopropyl)glycines [PDF]

open access: yes, 2004
The addition of carbon and heteroatom nucleophiles to (bicyclo[5.1.0]octadienyl)Fe(CO)2L+ cations 5 or 8 (L = CO, PPh3) generally proceeds via attack at the dienyl terminus on the face of the ligand opposite to iron to generate 6-substituted (bicyclo[5.1.

Monitoring the Dynamics of Alzheimer's Disease Biomarkers and the APOE–Tau Axis via Human Cerebral Organoids with Immuno‐SERS

open access: yesAdvanced Science, EarlyView.
Noninvasive and sensitive detection of tau protein dynamics across developmental stages and APOE genotypes remain a challenge in Alzheimer's disease (AD) research. This study reveals the dynamics of tau secretion in label‐free manner using surface‐enhanced Raman spectroscopy (SERS) and human cerebral organoids (hCOs). This study provides novel insights

Synthesis of Diaryl‐ and Dialkynylphosphinates From Ubiquitous PV Sources via a Redox‐Neutral Approach

open access: yesAdvanced Science, EarlyView.
Classical strategies for P─C bond formation rely on precursors (e.g., PH3, H2PO2, PCl3) obtained from P4, which is produced via the energy‐intensive thermal process. Here, an alternative, redox‐neutral approach is explored. Primary phosphate sources are activated with triflic anhydride (Tf2O) and 4‐dimethylaminopyridine (DMAP) to a versatile PV ...
