Enhancing Small Molecule Sensing With Aptameric Functionalized Nano Devices

Advanced Materials Technologies, Volume 11, Issue 14, 22 July 2026.
Unveiling an ultra‐sensitive, non‐invasive neurotransmitter sensor. For the first time, a nanoscale sensor for detecting an important neurotransmitter was demonstrated using micro‐electromechanical systems (MEMS) technology. Our approach utilized field‐effect transistor (FET)‐based readout to enable pico‐molar detection of biomarkers in sweat.

An Investigation into the Adsorption Characteristics of Grafted Mesoporous Silicates for the Removal of Tetramethyl Ammonium Hydroxide from Aqueous Solution

Adsorption Science & Technology, 2002
Four cubic mesoporous silicates (CMS), one unmodified and three grafted with amine, carboxylic and cyano surface functional groups, were prepared, characterised and compared as adsorbents for tetramethyl ammonium hydroxide (TMAH) from aqueous solution ...

Tetramethylammonium hydroxide (TMAH) treatment of dry-etched trenches on (010) β-Ga2O3 to enhance trench profiles [PDF]

AIP Advances
We demonstrated heated tetramethylammonium hydroxide (TMAH) etching (25 wt. % concentration, at 90 °C) as an effective post-dry-etch treatment for improving dry-etched trench profiles on (010) β-Ga2O3. This treatment successfully converted rough, tapered

COMPARISON OF IODINE DETERMINATION IN SPINACH USING 2% CH3COOH AND TMAH

Acta Scientiarum Polonorum: Hortorum Cultus, 2011
Tetramethylammonium hydroxide (TMAH) is the compound most commonly applied for iodine determination in environmental samples but, at the same time, is very harmful for human health when used as an analytical reagent.

High channel mobility at SiO2/GaN interface with different tilt angle trench sidewalls formed by wet etching treatment

APL Materials
The development of low-resistance Gallium nitride (GaN) trench metal-oxide semiconductor (MOS) channels is required. Since the trenches are formed by dry etching, their surfaces are inevitably exposed to plasma, leading to plasma-induced damage ...
