Catheters and medicals tubes are widely used to introduce pharmaceuticals and nutrients into arteries and veins, and
to drain fluids or urine from urethra or the digestive organs. It is well known that illuminated TiO<sub>2</sub> photocatalysts
can decompose most noxious or toxic organic compounds.
We studied the properties of titanium dioxide layers created by pulsed laser deposition from pure titanium and
titanium dioxide targets with the goal to develop urethral catheter using TiO2 coated plastic tube. To reach
crystalline structure at low substrate temperatures the radio-frequency discharge between the target and the substrate
was implemented. The crystalline structure of layers was determined by X-ray diffraction and Fourier Transform
Infrared Spectroscopy. Morphology was studied by atomic force microscopy (AFM). Using RF discharge, mixture
of anatase and rutile was found at substrate temperature of 90°C (which was reached only by RF discharge).
Thin films of various organic materials have been deposited by Matrix Assisted Pulsed Laser Evaporation (MAPLE)
technique. The principles, advantages, and difficulties of deposition technology are discussed. The focus is on target
preparation, solvents, studied materials, growth rate and films properties characterization.
