The search for new molecular architectures to improve the efficiency of sensors and optoelectronic devices is fundamental to enhance the effectiveness of nanostructured materials. In this present work, a di-ureasil hybrid compound (DUPTS) was spread at the air-water interface in order to form Langmuir monolayers. Phosphotungstic acid, H3PW12O40, PWA inserted in the aqueous subphase stabilized the...
The antimicrobial property of chlorhexidine is believed to be associated with its interaction of bacterium membrane, which calls for research on the identification of membranes sites capable of drug binding. In this study, we investigated the interaction of chlorhexidine digluconate, a known agent with bactericidal and bacteriostatic activities employed in the treatment of periodontal diseases, with...
Photopolymerized sol–gel monolithic columns for use in capillary electrochromatography were prepared in 125μm i.d. polyacrylate-coated fused-silica capillaries. The polyacrylate-coating, unlike the polyimide one, is transparent to the radiation used (≈370nm), and thus, no coating removal is necessary. This is a very important particularity since intrinsic capillary column characteristics, such as...
