چکیده
This Communication reports a novel colorimetric sensor to probe histidine in water based on para-sulfonatocalix[4]arene-modified silver nanoparticles; this highly selective sensor allows a rapid quantitative assay of histidine down to a concentration of 5 x 10(-6) M, providing a new tool for the direct measurement of histidine.

متن کاملInvestigation of para-sulfonatocalix[n]arenes [n = 6, 8] as potential chelates for (230)U.
Literature reports of the efficacy of para-sulfonatocalix[6]- and calix[8]-arenes as U(vi) complexants indicated that they might be useful for in vivo chelation of the novel therapeutic alpha-emitter (230)U. We have studied the complexation of U(vi) with para-sulfonatocalix[6]arene and para-sulfonatocalix[8]arene by time resolved laser induced fluorescence spectroscopy and using competition met...

The complexation of sodium molybdate with para-sulfonatocalix [4] arene was studied in thetemperature range from 20 to 40 °C and pH = 5.8 by spectroscopic method in water solution. Thestability constants of complexes were calculated by the multiwavelength analysis of spectral datausing SQUAD program. The equilibrium constant, spectroscopic data, molar absorptivities andconcentrations of all spe...
