Surface-enhanced resonance Raman scattering (SERRS) of rhodamine 6G was measured on confeito-like Au nanoparticles (CAuNPs). The large CAuNPs (100 nm in diameter) in aqueous dispersion systems showed stronger enhancing effect (analytical enhancement factor: over 10⁵) of SERRS than the small CAuNPs (50 nm in diameter), while the spherical Au nanoparticles (20 nm in diameter) displayed rather wea...
OBJECTIVES Information on the function of Candida albicans ATP-binding cassette (ABC) membrane transporter Cdr1p has come from studying the effect of gene inactivation in C. albicans and from heterologous Cdr1p expression in the yeast Saccharomyces cerevisiae. These approaches, however, give only an indirect indication of Cdr1p function in C. albicans itself. The objective of this study was to ...
The design and characterization of a system for in situ Raman analysis of surfaces prepared by ion soft landing (SL) is described. The performance of the new high vacuum compatible, low cost, surface analysis capability is demonstrated with surface enhanced Raman spectroscopy (SERS) of surfaces prepared by soft landing of ions of crystal violet, Rhodamine 6G, methyl orange and copper phthalocya...
Microfluidic systems based on fluorescence detection have been developed and applied for many biological and chemical applications. Because of the tiny amount of sample in the system; the induced fluorescence can be weak. Therefore, most microfluidic systems deploy multiple optical components or sophisticated equipment to enhance the efficiency of fluorescence detection. However, these strategi...
Correct interpretation of mass spectra is essential to our understanding of the ion chemistry occurring in the gas phase inside mass spectrometers and for constructing a solid knowledge from which mass spectrometry (MS) data of novel molecules will be interpreted. Assignments of product ions leading to incorrect dissociation mechanisms can also be dangerous in several disciplines such as in for...
A facile method is reported to synthesize macroporous silica films embedding rhodamine 6G. The were obtained by sol-gel and spin-coating processes. Results pointed out a dependence of pore formation on the addition 6G in film composition. probable process pores was attributed aggregation charged species from Although randomly distributed surface, size tuned at certain extent controlling evapora...
