Carbohydrate sensing with a metal-based indicator displacement assay.
A Pd-based indicator displacement assay for the fluorimetric sensing of carbohydrates has been developed. The assay allows the detection of saccharides in the low millimolar concentration range in water at neutral pH.
متن کاملMonitoring clinical levels of heparin in human blood samples with an indicator-displacement assay.
We report that a "tree-like" polymer of lysine is able to form a multi-ligand complex with a fluorescently labelled peptide, leading to the almost complete extinction of the optical signal that can be restored upon the introduction of heparin. This simple system allows, for the first time, the turn-ON fluorescent sensing of the anticoagulant in human blood at clinically relevant levels.
متن کاملDual-Wavelength Terahertz Metasurfaces with Independent Phase and Amplitude Control at Each Wavelength
We have designed, fabricated and characterized dual-wavelength metasurfaces that function at two assigned terahertz wavelengths with independent phase and amplitude control at each wavelength. Specifically, we have designed a dual-wavelength achromatic metasurface-based deflector deflecting the incident wave to the same direction at two selected wavelengths, which has circumvented the critical ...
متن کاملAn indicator-displacement assay for naked-eye detection and quantification of histidine in human urine.
A simple and efficient colorimetric method for the naked-eye detection and quantification of histidine in biological fluids was developed based on an indicator-displacement assay (IDA) and the Ni(2+)-histidine affinity pair. In this IDA approach, a commercially available dye, murexide, was used as the indicator and the selective detection of histidine was achieved based on the competition betwe...
متن کاملExhaust Emission Analysis of an Internal Combustion Engine Fuelled with Hydrogen-Ethanol Dual Fuel
The work presented in this paper is an attempt to evaluate the exhaust emission characteristics of a hydrogen-ethanol dual fuel combination with different percents of hydrogen substitutions (i.e. 0-80 % by volume and of 20 % increment ) at three different compression ratios of 7:1, 9:1 and 11:1. Experimental investigations have been carried out on a computer interfaced with; four-stroke cycle, ...
