Recently, this ambivalent character has been demonstrated for iridium-based microparticle LFL, where elemental iridium as starting material was oxidized, and the oxidized iridium reactant was

The microparticle samples were diluted in distilled water, and a drop of the particle suspension was applied on copper tape and then allowed to dry at RT overnight. The dried samples were then sputter-coated with gold

Nitric oxide (NO) has been proposed to be an important mediator of inflammation and carcinogenesis. Chronic inflammation, as found in

We developed a novel polymeric microparticle made of biodegradable poly(lactic-co-glycolic acid) (PLGA), which accumulates selectively in inflamed mucosa of patients with inflammatory bowel disease without interfering with the healthy mucosa.
