Topics of interest

Fabrication and study of thin layers of materials for implantology, tissue engineering and medicine. We fabricate and study thin layers of biocompatible materials, namely:

  • Hydroxyapatite for better osseointegration of implants (tooth, hip replacement)
  • Diamond-like-carbon for better biocompatibility (minimization of immune response a friction) implants such as joint replacement, arterial stents, heart valves
  • Titanium dioxide for photocatalytic and antibacterial applications for medical equipment (for example: urethral catheter)
  • Silver for antibacterial applications on implants
  • Organic and polymer materials (MAPLE technology) for sensors and tissue engineering
  • Bioglass, zircon, doped biocompatible layers (Ag, Mo, Cr, Ti …), nanocrystalline and nanocomposite layers, atd.

The goal is to develop new types biocompatible thin layers for application in medicine and sensor fields.

Modification of implant surface

We modify the surface of implant materials via mechanical, laser, and plasma (O2, NH2, O3) treatment for better biocompatibility. Resulting surfaces are studied with emphasis on support or inhibition of different cell growth.

Interaction study of UV laser irradiation with material

Interaction process of laser irradiation with material (biological tissue) is studied with thermocamera, fast infrared detectors, optically and spectroscopically. Damage or modification of tissue is evaluated in cooperation with medical faculties.

Preparation of nanoparticles of metals and silicon

We synthetize nanoparticles via pulsed laser ablation in liquid for drug delivery systems and biomolecular tagging.
