This month was not so sad and depressive as I expected despite of drowsy weather. Probably it took place thanks to many things which have to be done. I performed cytotoxicity assays of PEM films such like PLL/HA and PLL/ALG. I also prepared Chi/CS samples which were sent to Laser Center in Leoben (Austria) in order to introduce into their structure SiC nanoparticles by PACVD method.
