We presented a scalable fabrication method for the preparation of multilayered nano-prism vertex (NV)-tips whose dimensions can be controlled for tip-enhanced Raman spectroscopy (TERS). The NV-tip had sharp vertices (diameter ~20 nm) originated from the chemical lift-off process after the angle-grinding process, enabling high resolution imaging. TERS measurements were performed on brilliant cre...

Our recently developed approach of UHV-tip-enhanced Raman spectroscopy permits us to acquire Raman spectra of a few single brilliant cresyl blue (BCB) molecules and even a single one adsorbed on a Au(111) surface. This is substantiated by simultaneously recorded STM images. Furthermore, because of the reduced photobleaching in UHV, the time frame for spectral acquisition is sufficiently extende...

PURPOSE To evaluate the potential of heavier-than-water brilliant blue G (BBG-D(2) 0) to stain the internal limiting membrane (ILM) during chromovitrectomy. METHODS In a nonrandomized, prospective, clinical multicentre study, 71 consecutive chromovitrectomy interventions in 71 patients were analysed. During routine 23-gauge vitrectomy, conventional 0.25 mg/ml BBG was employed in 21 and 0.25 m...

In soils, colloidal transport has been identified as the most important pathway for strong adsorbing, environmental contaminants like pesticides, heavy metals, and phosphorus. We conducted a comparative dye tracer experiment using a Brilliant Blue (BB) solution and a Titanium(IV) oxide (TiO) colloid suspension (average particle size 0.3 μm), aiming to visualize and quantify colloid pathways in ...

Objective To assess visual and anatomical outcome of full thickness macular hole (FTMH) surgery with ILM peeling using brilliant blue G dye. Methods Thirty patients who had clinically evident macular hole were selected. Pre-operative Optical Coherence Tomography (OCT) was done. In all cases vitrectomy was performed via 23guage 3 ports pars plana (3PPV) vitrectomy system and Brilliant blue G d...

   In the present study, various size of Zinc Oxide Nanoparticles (ZnO NPs) was synthesized via Sol-gel method. The photocatalytic activity of the synthesized ZnO NPs was investigated for the Decolourization of three different colored dyes viz. Congo Red, Acid Blue 9 and Coomassie Brilliant Blue R-250 under UV lamp. Zinc Chloride (Zncl2) and Sodium Hydroxide (NaOH) were ...

There are few antagonists selective for subtypes of the several P2X receptors, but these are needed to identify the receptors expressed on native cells and tissues. In particular, P2X(4) and P2X(7) receptor subunits are colocalized on immune, epithelial, and exocrine gland cells, but both are relatively insensitive to suramin and pyridoxal-5-phosphate-6-azo-2',4'-disulfonic acid derivative. In ...

The permeability characteristics of newborn pig skin and adult rat skin, either fresh or stored, to model drugs were examined and compared. Special attention was paid to the design to a new experimental system suitable for evaluation of skin permeability to various substances. Two types of model substances were used; insulin, a poorly absorbable substance with high molecular weight as a represe...
