Eesti teadustaristu teekaardi objekti, „Nanomaterjalide tehnoloogiate ja uuringute keskuse“ (NAMUR+)põhieesmärk on välja arendada tipptasemel taristu nanomaterjalide uurimiseks ja rakendamiseks ning koondada see koos partnerite kõrgetasemelise uurimiskompetentsiga atraktiivseks multifunktsionaalseks nanomaterjalide ja nanoturvalisuse alaseid TA-teenuseid pakkuvaks tõmbekeskuseks. Selline keskus põhineb materjalide ja kõrgefektiivse energeetika (TÜ ja TTÜ) ning nanoturvalisuse (KBFI Keskkonnatoksikoloogia labor) teadusgruppide kompetentsil.
NAMUR+ projekti eesmärgiks nanoturvalisuse valdkonnas on täiendada KBFI Keskkonnatoksikoloogia labori taristut nanomaterjalide bioloogiliste mõjude ja ohtlikkuse uuringuteks. Loodav taristu võimaldab iseloomustada nanomaterjalide ohutust nii tootjale, tarbijale kui ka ümbritsevale keskkonnale ning leida nanomaterjalidele uusi bio- ja meditsiinivaldkonnaga seotud kasutusalasid. Erinevate teenuste raames on võimalik hinnata nanomaterjalide keskkonnaohtust vetikatele, kirpvähilistele ja veetaimedele (OECD standardtestid), antimikroobseid omadusi, tsütotoksilisust imetajate rakkudele ja nanoosakeste bio-interaktsioone.
Projekti tulemused
NAMUR+ projekti tulemusena on hangitud ja töösse rakendatud 3 baaskonfiguratsioonis aparatuuri tugistruktuuri, mis moodustavad ühe osa KBFI nanoturvalisuse infrastruktuurist :
Ökotoksikoloogia tugistruktuur
Termostateeritav ja valgusreguleeritav kliimakamber AlgaeTron AG230 (A) keskkonnaohutuse testide läbiviimiseks ja stereomikroskoop Nikon SMZ1270 (B) koos videokaameraga testorganismide visualiseerimiseks. Testorganismid Daphnia magna (C) ja Thamnocephalus platyurus (D) pildistatud Nikon SMZ1270 stereomikroskoobiga.
In vitro toksikoloogia tugistruktuur
UVA-kliimakamber Climacell 111 EVO (A) nanomaterjalide antimikroobsuse ja ohutuse uuringuteks, mikroplaadipesija ThermoScientificTM Wellwash ELISA (B) testide läbiviimiseks ja automatiseeritud rakulugeja Logos Biosystems Luna-IITM(C) koekultuurirakkude arvukuse ja elulevuse määramiseks ning invertmikroskoop Zeiss Axio Vert.A1 (D) koos videokaameraga Axiocam 208 rakukultuuride visualiseerimiseks.
Nano-bio interaktsioonide tugistruktuur
Laser-skaneeriv konfokaalmikroskoop Zeiss LSM800 nanomaterjalide ja rakkude interaktsioonide uurimiseks.
Projekti raames jätkatakse kompetentse personali koolitamist hangitud seadmete kasutamiseks, millega tagatakse nanoturvalisuse uuringute taristu edukas kasutamine teadus- ja arendustööks ning uute teenuste väljatöötamiseks.
