Liposomes made from phospholipids and containing sulforhodamine dye (1-50 mM) have been irradiated with nanosecond and picosecond laser pulses. Individual liposomes were locally heated by laser absorption of dye dimers during a single laser pulse, and heating was sufficient to release the liposome contents. The extent of dye release produced by a single laser pulse was shown to be quantitativel...

The sonochemical technique has already been proven as one of the best coating methods for stable functionalization of substrates over a wide range of applications. Here, we report for the first time on the simultaneous sonochemical dyeing and coating of textiles with antibacterial metal oxide (MO) nanoparticles. In this one-step process the antibacterial nanoparticles are synthesized in situ an...

introduction:  no modality has been identified as the treatment of chice for treating common warts. cryothearpy and pulsed-dye laser (pdl) are among common modalities for treating these lesions. the aim of this study was to compare pulsed dye laser with cryotherapy in terms of efficacy and complications. methods:  of a total of 46 patients enrolled in this study, 7 patients withdrew the study, ...

This report describes the synthesis of an antibacterial material consisting of a gemini quaternary ammonium salt (gemini-QUAT) immobilized on ferrite powder, and its antibacterial activity. A gemini-QUAT containing two pyridinium residues per molecule, 4,4'-[1,3-(2,2-dihydroxylmethyl-1,3-dithiapropane)]bis (1-octylpyridinium bromide), was immobilized on ferrite powder by a reaction between the ...

introduction: trichophyton rubrum is one of the most common species of dermatophytes which affects superficial keratinous tissue. it is not especially virulent but it can be responsible for considerable morbidity. although there are different therapeutic modalities to treat fungal infections, clinicians are searching for alternative treatment because of the various side effects of the present t...

Dye-laser technology has seen very significant progress over the last 39 years since the first demonstration of this device technology. Dye lasers offer efficient emission in the visible and near-infrared bands by direct generation of laser light. The initial emphasis was on the liquid-phase technology, and is the one very successful liquid laser. More recently the research emphasis has been so...
