Selective colorimetric sensing of mercury(ii) using turn off-turn on mechanism from riboflavin stabilized silver nanoparticles in aqueous medium.
Summary of "Selective colorimetric sensing of mercury(ii) using turn off-turn on mechanism from riboflavin stabilized silver nanoparticles in aqueous medium."
A simple Hg(2+) sensor has been developed using the vitamin B2 (riboflavin) stabilized Ag nanoparticle via a "turn off"-"turn on" mechanism; both the colour and photoluminescence properties of the riboflavin solution are used as sensitizing tools showing a sensitivity up to 5 nM Hg(2+) concentration.

The first DNA-binding protein motif to be recognized. Helix-turn-helix motifs were originally identified in bacterial proteins but have since been found in hundreds of DNA-BINDING PROTEINS from both eukaryotes and prokaryotes. They are constructed from two alpha helices connected by a short extended chain of amino acids, which constitute the "turn." The two helices are held at a fixed angle, primarily through interactions between the two helices. (From Alberts et al., Molecular Biology of the Cell, 3d ed, p408-9)
Used as an indicator in titrating iron and for the colorimetric determination of chromium and the detection of cadmium, mercury, magnesium, aldehydes, and emetine.
Substances causing insects to turn away from them or reject them as food.
Stable mercury atoms that have the same atomic number as the element mercury, but differ in atomic weight. Hg-196, 198-201, and 204 are stable mercury isotopes.
Unstable isotopes of mercury that decay or disintegrate emitting radiation. Hg atoms with atomic weights 185-195, 197, 203, 205, and 206 are radioactive mercury isotopes.
We describe ZRL1, a turn-on colorimetric and red fluorescent zinc ion sensor. The Zn(2+)-promoted ring opening of the rhodamine spirolactam ring in ZRL1 evokes a 220-fold fluorescence turn-on response...
Iodide plays a vital role in many biological processes, including neurological activity and thyroid function. Due to its physiological relevance, a method for the rapid, sensitive, and selective detec...
A colorimetric nanoprobe-mercury-specific DNA-functionalized gold nanoparticles (Au-MSD) was developed for sensing Hg(2+). The new mercury-sensing concept relies on measuring changes in the inhibition...
Exposure to even very low levels of lead, cadmium, and mercury ions is known to cause neurological, reproductive, cardiovascular, and developmental disorders, which are more serious problems for child...
A new probe for Cu(2+) based on the Cu(2+)- induced reversible ring-opening mechanism of the rhodamine spirolactam was described. It displayed a highly selective and sensitive "turn-on" fluorescent an...
The purpose of this study is to determine whether there are detectable health effects of low-level mercury exposure (from normal exposure to mercury-containing dental fillings) in the know...
Fish can provide pregnant women with omega-3 fatty acids for fetal brain development but some fish contains high levels of mercury which is detrimental to fetal brain development. The hypo...
Acanthosis Nigricans is skin disease that associated with hyperinsulinemia. Clinical is velvety hyperpigmented plaques on neck, axilla, groin. If hyperinsulinemia is improved by treated wi...
The goal of the study is to find out how much mercury is in the blood, urine, and stools of premature and low birth weight infants who have received standard childhood vaccines that are gi...
The aim of the PRAM study was to determine whether women diagnosed with hypertension in pregnancy, using the traditional mercury device, have the same pregnancy outcomes when blood pressur...
