Saloni Sinha presents the development of our medical anti-fog VitreOx™ and blood evacuating medical device HemoClear™on surgical lenses. This is R&D supported by SiO2 NanoTech and the results of SiO2 NanoTech - ASU SiO2 CIMD Lab tech transfer. She gave her talk at the 2014 American Physical Society (APS) 4 C Fall meeting on October 18, 2014, in Orem Utah. Saloni covered four of our patents, two by ASU (HemoClear™) and two by SiO2 NanoTech LLC (VitreOx™, an SiO2 NanoTech trademark). Two of these patents have been recently issued, as posted below. Salonis talk was presented in the Bio-Physics session. https://youtube/watch?v=pHOY1cUf4vs The TITLE of her abstract and presentation was: HemoClear™: A Thin Fluid Film Device (TFFDTM) and Model to Eliminate both Fogging and Blood on Surgical Lenses ABSTRACT: In closed body cavity surgery, blood and water condensation can obstruct surgeons’ view through scopes lenses. This forces surgeons to repeatedly remove scopes to wipe lenses during surgery, and increases surgery duration, infection risk and scarring by 10- 40%. HemoClear™, a Thin Fluid Film Device (TFFD™), is a layered emulsion combining VitreOx™and fibrinogen. [1,2] VitreOx™is an anti-fog TFFD™, free of optical aberration, optically transparent, and super-hydrophilic, stable for up to 48 hours in closed body cavity surgery. We find that fibrinogen can evacuate blood without interfering with the anti-fog properties VitreOx™, via the hemo-affinity of fibrinogen and hydro-affinity of VitreOx™. The mixing and layering of the components of HemoClear™ are tested via in vitro clinical trials to optimize our TFFD™ with the smallest effective dose of fibrinogen. A model for 2-D versus 3-D condensation and hemo-affinity will be discussed. [1] N. Herbots, et al. Prov. Pat. filed 11/10/09, 11/3/11 [2] N. Herbots, et al. PCT/US12/62196 Internat.
