Colorimetric Detection of Salicylic Acid in Aspirin Using MIL-53(Fe) Nanozyme

Salicylic Acid and Aspirin Inhibit the Activity

Salicylic acid in the serum of subjects not taking aspirin. Comparison of salicylic acid concentrations in the serum of vegetarians, non-vegetarians, and patients taking low dose aspirin.

AIMS To determine serum salicylic acid concentrations in non-vegetarians and vegetarians not taking salicylate drugs, and to compare these concentrations with those found in patients taking aspirin, 75 mg daily. METHODS Serum samples were obtained from vegetarians (n = 37) and non-vegetarians (n = 39) not taking salicylate drugs. Non-vegetarians and vegetarians were recruited from the communi...

Colorimetric cyanide detection using an azobenzene acid in aqueous solutions.

An azo-based dye (I) was designed for the detection of cyanide by utilizing a new indirect method. In the presence of Cu(II), compound I could give rise to visible red-to-yellow color change. The resultant yellow solution could change to red immediately upon the addition of trace cyanide, with the detection limit of 0.15 ppm, but no changes were observed in the presence of other anions, includi...

Assessing Stability of Gold Nanoparticles in Presence of Two Enzymes, RNaseA and RNaseH, Using Colorimetric Detection

Gold nanoparticle-based diagnostic methods have attracted much attention due to their simplicity, high sensitivity and low cost. These methods are mostly used for early and efficient detection of various pathogenic factors and assessment of gene expression and nanoparticles stability. In this study, melon plants were cultured in vivo and then, RNA was extracted from leaf explants. A 40 bp probe...

Salicylic Acid sans Aspirin in Animals and Man: Persistence in Fasting and Biosynthesis from Benzoic Acid

Salicylic acid (SA), which is central to defense mechanisms in plants and the principal metabolite of aspirin, occurs naturally in man with higher levels of SA and its urinary metabolite salicyluric acid (SU) in vegetarians overlapping with levels in patients on low-dose aspirin regimens. SA is widely distributed in animal blood. Fasting for major colorectal surgery did not cause disappearance ...
