1. ABSTRACT  Fruits of Romanian native plants from Adoxaceae family (European Cranberrybush - Viburnum opulus L. –E1 and European Black Elderberry - Sambucus nigra L.-E2) have biological activity mainly due to their high content of anthocyanins and other polyphenols. They were used to obtain new nanomaterials based on gold nanoparticles. We have controled the size, shape and surface morphology of these nanomaterials (AuNPs-E1, AuNPs-E2) prepared by using a green method; the new nanomaterials have been used in medicine to treat some skin diseases.  We have evaluated their in vitro and in vivo effect and we have identified the effectiveness of new topic therapies based on nanotechnology using high frequency ultrasound.

(AuNPs-E1 and AuNPs-E2) were prepared and characterized by UV-Vis and FTIR spectroscopy and by Transmission Electron Spectroscopy (TEM) (diameters between 25-100 nm) There were assessed cytotoxicity tests of the extract alone and of the functionalized nanoparticles; To study the antiinflammatory effect, keratinocytes treated with non-toxic doses of anthocyanins and nanoparticles were exposed to increasing doses of UVB irradiation The histograms of the skin thickness for 8 patients presented an involution of diseases after treatment, fact that indicates the very good antiinflammatory effect of our nanomaterials.
