Abstract:
Novel Zr-based metal-organic framework (MOF) chemosensors useful for detection, recognition, removal, and separation of heavy metals are provided. Also provided are methods for preparation of the chemosensors and processes for detection, recognition, removal, and separation of heavy metals using the chemosensors.
Abstract:
Sensors and methods for determination of analytes are provided. Analytes including explosives (e.g., RDX or PETN) may be determined by monitoring, for example, a change in an optical signal of a material upon exposure to the analyte. In some embodiments, the analyte and the material may interact via a chemical reaction to form a new emissive species. Embodiments described herein may provide inexpensive sensors with high selectivity and sensitivity.
Abstract:
Methods for the chiral separation and quantitative determination of the d - and l - enantiomers for amphetamine and methamphetamine in bodily fluids and tissues are provided. The method comprises providing a bodily fluid or tissue sample from a subject, extracting target analyte(s) from the sample, followed by eluting on a liquid chromatography column comprising a chiral stationary phase to yield an eluent, which is then analyzed for the presence of the analytes using a mass analyzer.

Abstract:
A method for the detection of explosives using a single sample. The explosives include nitro aliphatic and nitro aromatic-based explosives. The method includes steps which require different pHs to discriminate between these types of explosives and at least in the detection step of the nitro aliphatic explosive requires the presence of a nitro aromatic compound. A kit for detecting explosives which includes a medium for collecting a sample, a base optionally impregnated on the medium; and a nitro aromatic solution for detecting a nitro aliphatic explosive by contacting the solution with the sample on the medium. A reagent including a nitro aromatic compound, having one or more additional electron withdrawing groups, in the presence of a basic compound usable for detecting nitro aliphatic explosives.
