Fabrication of nanoperforated GaN nanomembranes

BRANISTE, T.; VOLCIUC, O.; TIGINYANU, I. (Tehnica UTM, 2014)

We report on fabrication of suspended ultrathin GaN membranes nanoperforated in an ordered fashion using direct writing of negative charges by focused ion beam and subsequent photoelectrochemical etching of the GaN epilayers. ...
Guiding of endothelial cells targeted with semiconductor material nanoparticles

BRANISTE, T.; TIGINYANU, I.; HORVATH, T.; RAEVSCHI, S.; GRIDENCO, O.; CEBOTARI, S.; HILFIKER, A. (Technical University of Moldova, 2016)

We found that ECs attract free NPs and, depending on the NP concentration, the cellular activity is slowed down resulting in lower cellular mobility. Nevertheless, cellular proliferation does not seem to be affected as ...
Light-induced motion of microengines based on microarrays of TiO2 nanotubes

CIOBANU, V.; GUIX, M.; ENACHI, M.; POSTOLACHE, V.; FOMIN, V. M.; SCHMIDT, O. G.; TIGINYANU, I. (Technical University of Moldova, 2016)

In this work, we demonstrate that TiO2 micro/nanotubular structures, fabricated by means of electrochemical anodization of Ti sheets, can act as self-propelled microengines when they are exposed to UV irradiation.
