The discovery that mammalian cells can survive late-stage apoptosis challenges the general assumption that active caspases are markers of impending death. However, too...
A 3-channel biosensor based on spectral correlation interferometry (SCI) has been adapted for direct optical detection of antigens by measuring changes in thickness of...
A rapid and highly sensitive point-of-care (PoC) lateral flow assay for phospholipase A2 (PLA2) is demonstrated in serum through the enzyme-triggered release of a new ...
A rapid and simple approach for visible determination of mercury ions (Hg(2+) ) in aqueous solutions was developed based on surface plasmon resonance phenomenon using ...
Chondroitin sulfate tetrasaccharide ligand conjugates, namely GlcA-GalNAc6S-GlcA-GalNAc4S6S (CS-C+E) 1, GlcA2S-GalNAc6S-GlcA2S-GalNAc4S6S (CS-D+T) 2, GlcA-GalNAc4S6S-G...
In recent years, many improvements have been made in foodborne pathogen detection methods to reduce the impact of food contamination. Several rapid methods have been d...
A sensitive aptasensor based on a nanocomposite of hollow titanium dioxide nanoball, three-dimensional reduced graphene oxide, and polypyrrole (TiO2/3D-rGO/PPy) was de...
A new electrochemiluminescence (ECL) sensor was developed for 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodGuo) quantification and Escherichia coli formamidopyrimidine-D...
Lead ion (Pb(2+), a heavy metal ion existed every aspect of life) is one of the most important hazards for environment and human health. Herein we design an in-situ am...
Hydrogen sulfide (H2S) is an endogenous gaseous signaling molecule with potent anti-inflammatory properties. Exogenous application of H2S donors, administered either a...
Distinguishing between the two enantiomers of a molecule is a challenging task due to their nearly identical physical properties. Time-consuming chromatography methods...
Silicon nanowire (SiNW) field-effect transistor (FET) biosensors have already been used as powerful sensors for the direct detection of disease-related biomarkers. How...
Herein, we describe an ultrasensitive specific biosensing system for detection of sarcosine as a potential biomarker of prostate carcinoma based on Förster resonance e...
The quintessential property of developing cardiomyocytes is their ability to beat spontaneously. The mechanisms underlying spontaneous beating in developing cardiomyoc...
The RAG endonuclease consists of RAG1, which contains the active site for DNA cleavage, and RAG2, an accessory factor whose interaction with RAG1 is critical for catal...
A fluorescent "turn off-on" pattern for the detection of herring sperm DNA (hsDNA) had been designed through utilizing the interaction between polymyxin B sulfate (PMB...
Extracellular nucleic acids freely circulating in blood and other physiologic fluids are important biomarkers for non-invasive diagnostics and early detection of cance...
Cell-matrix adhesion plays a key role in controlling cell morphology and signaling. Stimuli that disrupt cell-matrix adhesion (e.g., myeloperoxidase and other matrix-m...
Anastasis (Greek for "rising to life") refers to the recovery of dying cells. Before these cells recover, they have passed through important checkpoints of apoptosis, ...
A graphene channel field-effect biosensor is demonstrated for detecting the binding of double-stranded DNA and poly-l-lysine. Sensors consist of chemical vapor deposit...
