A possibility of laser printing single diamond nanoparticles with luminescent SiV centers is demonstrated. To provide the transfer, a target consisting transparent sapphire plate and an absorbing thin titanium film (600 nm thick) coated was irradiated KrF excimer ("lambda"=248 nm, "tau"=20 ns). Optimal values fluence have been determined technique for applying labels targeted transfer has devel...

A new cell surgery technique has been developed to produce well-defined alterations in cells and tissue without detectable heating and/or other structural damage in the surroundings. The technique involves the use of an argon fluoride excimer laser, in the deep ultraviolet (UV) region of the spectrum at 193 nm, which is guided through a glass pipette filled with a positive air pressure. To demo...

We prepared ultrafine Fe-Pt alloy nanoparticle colloids by UV laser solution photolysis (KrF excimer laser of 248 nm wavelength) using precursors of methanol solutions into which iron and platinum complexes were dissolved together with PVP dispersant to prevent aggregations. From TEM observations, the Fe-Pt nanoparticles were found to be composed of disordered FCC A1 phase with average diameter...

BACKGROUND/AIMS "Orientation teeth" at the donor trephination margin and correspondent "notches" at the host margin facilitate graft orientation and avoid "horizontal torsion" induced by asymmetric suture placement. In this study the quality and reproducibility of these structures created by non-mechanical laser corneal trephination were compared using two laser emissions. METHODS The procedu...

PURPOSE Ablating and cutting vitreoretinal membranes using a 193-nm excimer laser-based microsurgical system. METHODS A 193-nm microsurgical system enables delivery of the beam into a fluid medium to cut preretinal and subretinal membranes. Two patients with proliferative diabetic retinopathy and one patient with proliferative vitreoretinopathy were treated with this new device. RESULTS Gen...

Hyperopia is a common refractive error that is usually corrected with eyeglasses or contact lenses. Following the fast advancement in refractive surgery and technology, eyeglasses or contact lenses were no longer the single treatment option in refractive errors. Today, extraction of transparent lens and intraocular lens implantation, phacic intraocular lens applications and corneal surgeries ar...

Raman shifting of tunable ArF excimer laser radiation in a mixture of H(2) and D(2) produces tunable radiation in the 224-nm region as a result of Stokes shifting the frequency of the fundamental radiation (193 nm) once in both H(2) and D(2). At a total pressure of 25 bars, a 19% H(2) in D(2) mixture is found to provide a maximum conversion efficiency (2.5%) to the 224-nm range. Both fundamenta...

UNLABELLED Narrowband ultraviolet B (NB-UVB) phototherapy, with a 308-nm xenon chloride excimer laser, and targeted UVB phototherapy have produced encouraging therapeutic results for vitiligo. However, very few studies employing broadband UVB exist. Moreover, there has been no direct comparison study between broadband UVB and NB-UVB for the treatment of vitiligo. The aims of this study were to ...
