Spectral differences between normal and abnormal tissue observed to date appear to be due to different averaging processes of spectral patterns that differ according to the cell’s biochemistry, due to its state of maturation, differentiation, and development. Thus, disease perturbs the distribution of cells in the different stages of maturation, differentiation, and development. Previous FTIR m...

Fourier transform IR (FTIR) microspectroscopy at a spatial resolution of 18 microm was used to study skin fibroblasts and giant sarcoma cells. Both cell lines were derived from the same patient; they were metabolically active and in the exponentially growing phase. The IR spectra were acquired for the nuclei and cytosol of untreated cells, cells washed with ethanol, and cells treated with RNase...

Discovered more than 40 years ago, microplastics have become a major environmental issue. With increasing global plastic production, are of growing concern. Landfills been pinpointed as primary sources to surface waters and they have, in fact, identified quantified such. Due their small size, different polymers interfering non-plastic materials, difficult analyse complex matrix such leachate. T...

The release of perylene from octadecylsilyl (ODS)-silica gel into water using a nonionic surfactant was kinetically studied by single microparticle injection and absorption microspectroscopy techniques. The release of perylene from the porous microparticles significantly depended on the surfactant concentration. The release rate constant was inversely proportional to the microparticle radius;...
