Cytotoxicity and biointeractions of nanosilver in macrophages

Pratsinis A., Pratsinis S.E., Hervella P., Leroux J.-C., Pratsinis A., Pratsinis S.E., Sotiriou G.A., ETH Zürich, CH

Silver nanoparticles (nanosilver) are broadly used today in textiles, food packaging, household devices and bioapplications, prompting a better understanding of their toxicity and biological interactions. Here, nanosilver of well-defined size (5.7 to 20.4 nm) supported [...]

Aerosol manufacturing of plasmonic biosensors with silica coated nanosilver

Sotiriou G.A., Blattmann C.O., Pratsinis S.E., ETH Zürich, CH

Development of biosensors for medical applications is an on-going research field of great importance. In particular localized surface plasmon resonance (LSPR) biosensors show a high potential to detect analytes at low concentrations in biological fluids. [...]

The study of anti-reflection coatings doped with Ag nanoparticles utilized in solar cells

Zhan S., Zhang Q., Fan X.H.J., Zhang Q., Ji R., Wang Y., Miao T., Sun Q., Sun X., Hao Y., Sun Q., Sun X., Northwest University, CN

As solar energy is a renewable,clean energy sources,it has been focused rearchers attention for a long time.In this study ,We expect to enhance the transimittance of anti-reflection(AR) films which are used in solar cells.First,The Ag [...]

Photogeneration Kinetics of Ag Nanoparticles in Light Sensitive Polymer Films

Korchev A.S., Foti K., Sartin M., Slaten B.L., Gale W., Mills G., Auburn University, US

Ag nanoparticles were generated within light-sensitive films composed of poly(ether ether)ketone, SPEEK and poly(vinyl alcohol), PVA. The benzophenone (BP) groups of SPEEK act as sensitizers; excited states of these functions abstract H-atoms from PVA forming [...]
