The size of porous silicon particles is also an important factor. Particles smaller than 3 pm have been demonstrated to be cytotoxic to monocytes (Ainslie et al. 2008) loss in Caco-2 cell metabolic activity was seen with particles between 1.2 and 25 pm in size (Santos et al. 2010). In contrast, particles below 500 nm were demonstrated to be nontoxic to lymphoma cells (De Angelis et al. 2010), and particles smaller than 1 pm did not cause any cytotoxic effects with macrophage and endothelial cells (Godin et al. 2012). [Pg.4]

Foraker et al. 2003). In the paper, Foraker et al. used microfabricated porous silicon particles to enhance insulin permeabihty across Caco-2 cell monolayer, which is commonly used in vitro model of the human small intestinal mucosa to predict the absorption of orally administrated drugs. They observed that the flux of insulin across the cell monolayer was approximately 50-fold compared with liquid formulations and nearly 10-fold higher compared with liquid formulations with permeation enhancer, if insulin was loaded in PSi. [Pg.113]

Porous silicon particles could be utilized in a variety of consumer care applications if their cost of manufacture becomes low enough. Silica and porous silica are already widely used by the toothpaste and cosmetic industries, and porous silicon offers superior mechanical properties for teeth cleaning and very different optical properties for cosmetics. Partial thermal oxidation has been used to improve shelf life in liquid formulations and to match brown skin tones. Preliminary mouthfeel testing for oral hygiene products has been carried out, but formalized skin-feel testing and optimization is required for numerous dermatological products. Product examples discussed include multifunctional dentifrice abrasives, sunscreens, bronzers, foundation and makeup additive, and anti-aging formulations. [Pg.544]
