The charged species inside biofluids (blood, interstitial fluid, sweat, saliva, urine, etc.) can
reflect the human body's physiological conditions and thus be adopted to diagnose various …

Ions are ubiquitous biological regulators playing a key role for vital processes in animals
and plants. The combined detection of ion concentration and real-time monitoring of small …

The concentration of sodium and potassium ions in biological fluids, such as blood, urine
and sweat, is indicative of several basic body function conditions. Therefore, the …

In this paper, the concentrations of chloride salts (sodium chloride (NaCl), potassium
chloride (KCl), magnesium chloride (MgCl 2), calcium chloride (CaCl 2)) and a carbonate …

L-tryptophan functionalized AgNPs were successfully fabricated using a one-pot synthesis
method and assessed as a colorimetric probe for rapid and accurate determination of Mg 2+ …

Field effect transistors (FETs)-based detection probes are powerful platforms for
quantification in biological media due to their sensitivity, ease of miniaturization, and ability …

An amyloid-beta peptide (Aβ) is generally believed to be a pathological marker of
Alzheimer's disease (AD), but it is still of great significance to explore the upstream and …

The design of high-performance cavity for the accurate and efficient operation of various pH
sensors remains challenging. In this paper, we report the simplistic design of an epoxy-free …

Ion-sensitive field-effect transistors (ISFET) are used in various sensing applications
including electrochemical biosensing. In this study, analytical models of Ta2O5, Si3N4, and …

PH sensors are widely used in food processing, health monitoring, water quality monitoring,
