Penetration of nanoparticles in 5 nm to 400 nm size range through two selected fibrous media
Due to the strong development of nanotechnologies, ultrafine particles could represent a growing hazard for workers health. When it is not possible to reduce the risk at its source, filtration systems are one of the means used to limit the exposure to hazardous substances such as airborne particles. The aim of this study is to measure the penetration of nanoparticles on a very large diameter ra...
متن کاملUV absorbance of the human cornea in the 240- to 400-nm range.
PURPOSE To determine the UV absorbance of the corneal layers (epithelium, Bowman layer, stroma) in the 240- to 400-nm range. METHODS Consecutive slices (100 microm) of human cadaveric corneas were cut, and the UV absorbance of each sample was determined in a scanning spectrophotometer. In some cases the epithelium was scraped off and its absorbance measured separately. RESULTS The investiga...
متن کاملLight scattering in Intralipid-10% in the wavelength range of 400-1100 nm.
The absorption, scattering, and anisotropy coefficients of the fat emulsion Intralipid-10% have been measured at 457.9, 514.5, 632.8, and 1064 nm. The size and shape distributions of the scattering particles in Intralipid-10% were determined by transmission electron microscopy. Mie theory calculations performed by using the particle size distribution yielded values for the scattering and anisot...
متن کاملVapor phase mediated cellular uptake of sub 5 nm nanoparticles
Nanoparticles became an important and wide-used tool for cell imaging because of their unique optical properties. Although the potential of nanoparticles (NPs) in biology is promising, a number of questions concerning the safety of nanomaterials and the risk/benefit ratio of their usage are open. Here, we have shown that nanoparticles produced from silicon carbide (NPs) dispersed in colloidal s...
