Abstract

Microsphere-assisted microscopy allows the limit of the diffraction of light to overcome while being non-invasive, full-field, label-free, and easy-to-implement. However, the observation of translucent samples remains difficult using a classical bright-field illumination. In this work, a method is presented for the inspection of quasi-transparent sub-diffraction-limited structures by using dark-field illumination in the transmission mode. Glass-imprint features, having a size of 250 nm, as well as fixed mouse brain cells have been visualized using the dark-field microsphere-assisted technique. The possibility to observe feature sizes up to 100 nm has been demonstrated in air using a 25-mu m-diameter glass microsphere combined with an optical microscope, opening new possibilities for biological imaging.

Abstract

Novel fullerene-grafted poly(3-hexylthiophene) (P3HT)-based rod-coil block copolymers have been synthesized. The regioregular P3HT rod block has been synthesized by a modified Grignard metathesis reaction (GRIM). An original in situ end-capping reaction has been developed in order to convert the P3HT block into an efficient macro-initiator for the nitroxide-mediated radical polymerization (NMRP) of the coil block. Controlled radical polymerization of the second poly(butylacrylate-stat-chloromethylstyrene) [P(BA-stat-CMS)] block has been done through various conditions leading to different coil block lengths. The final electron donor-acceptor block copolymer has been obtained after C 60 grafting in soft conditions. Copolymers have been characterized by 1 H NMR and size exclusion chromatography. Optical characterizations, before and after C 60 grafting, are reported.

Abstract

Polycrystalline lead iodide layers with crystallites in the micrometer range have been prepared using a solution growth method from water and polyvinyl alcohol. Structural, electrical and optical measurements have been performed to characterize these layers and compare their properties to those of polycrystalline films prepared by solution growth in pure water. Most of these properties are very similar. The main difference comes from the photoresponse: that of films prepared with PVA remains high but presents an unusual behaviour with temperature. This has been related to the presence of a trapping/recombination energy level in the band gap. (© 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
