https://www.selleckchem.com/products/ly364947.html A new probe RB-CR for the detection of Cr3+ was constructed based on the conjugation between rhodamine B and phenylthiourea. The Cr3+ could trigger opening of the rhodamine spirolactam of RB-CR upon complexation selectively, sensitively and rapidly, resulting in a pronounced enhancement of absorption and fluorescence signal. Further fluorescence imaging study has suggested that RB-CR could be applied as a probe for Cr3+ surveillance in living HepG2 cells with low cytotoxicity, which provide us the feasibility of exploring the Cr3+ recognition process by the turn-on fluorescence response.Spectra measured in various ranges of temperature are usually slightly different from each other in shape and position of the bands. Although the displayed inconsistencies are rather small, yet may lead to incorrect analysis and interpretation of the collected spectrothermal data. Thus the unspecific spectral effects induced by temperature, in particular the thermal shifts and broadening of the bands, have to be compensated. In the paper, a simple two-step method of thermospectral dataset uniformisation is presented. Thermally induced 'movement' of the bands is approximated as a linear function of the difference of temperatures, so the co-shifting of the spectra is done linearly. Thermal broadening is mimicked by convoluting the low-temperature signal (spectrum) with a Gaussian or Lorentzian spreading filter. Proper widths (values of FWHM) of these filters, used to uniform the whole dataset, are assumed to depend on the difference of temperatures, in a form of one-parameter functions. This assumption, which has been empirically confirmed, is a fundamental premise of the method of Partial Compensation for Thermal Broadening (PCTB). Optimal values of the parameters of all the functions, used to compensate both thermal shifting and broadening, are found by the Evolutionary Rank Analysis (ERA) applied on an evolving data matrix.
