Abstract:
The optical characteristics of a single-layer and double-layer antireflection coating for different substrates are considered. Methods of simultaneous blooming of s - and p - polarization component of light are shown. The refractive index and thickness of the layers necessary for blooming the substrates with a given refractive index at an arbitrary angle of light incidence are determined. The urgency of the task of creating new optical materials with low refractive index is shown.

<p>The aims of this study are to first immobilize positively charged gold nanorods to negatively charged cell culture surfaces. Second, to use polyelectrolytes for controlling the distance between gold nanorods and fluorophores. This is used to optimally determine the distance, of which maximum fluorescence enhancement is achieved, between gold nanorods and fluorophores. In order to approach these aims, we use UV/VIS absorption spectroscopy, fluorescence spectroscopy, atomic force microscopy, and ellipsometry. The results show that we could control the immobilization of gold nanorods on plasti

In this study, ZnO, MgO, In2O3, SnO2, iron oxide nanowires and nanorods were successfully produced by using Pulsed Laser Deposition. It was observed that the parameters, such as gold nanodots, number of pulses on the targets, temperature, oxygen pressure and substrate, contribute to various results. Different metal catalyst or substrate results in different morphology. Controlling oxygen pressure and substrate temperature was found to be crucial for the ZnO, In2O3 and iron oxide nanowires growth using this technique.

Abstract:
Cancer cells that survive chemotherapy treatment often develop resistance to the administered chemotherapeutics, as well as to many other types of drugs, because the cancer cells increase their production of efflux pumps in the cell. This undesired phenomenon of resistance to cancer drugs is known as multidrug resistance. This work uses a novel drug carrier, called an eLiposome, to achieve cytosolic drug delivery to kill multidrug-resistant cancer cells. An eLiposome consists of a perfluoropentane (PFC5) emulsion droplet inside of a liposome. Folate attached to the eLiposome facilitates uptake

Cellular internalization of large therapeutic agents such as proteins or nucleic acids is a challenging task because of the presence of the plasma membrane. One strategy to facilitate intracellular drug uptake is to induce transient pores in the cell membrane through physical delivery strategies. Physical approaches are attractive as they offer more generic applicability compared with viral or biochemical counterparts.

WOX nanorods were prepared by the hydrothermal method, followed by spin coating SnO2 precursor solution into thin film and calcinated to form the heterojunction. The results from SEM, AFM and XRD showed that the deposition of SnO2 on top of WOX nanorods formed a smoother surface that is beneficial for perparing the perovskite layer with fewer holes.

In the first part, we employ the asymmetric silica coating technique onto gold nanorod (AuNR) to form a non-uniform silica coating with two long-axis ends of the AuNR nearly exposed. The very thin coating at two ends leads to a kinetically faster reaction etching rates. The etching result of AuNR clearly indicates that the aspect ratio of gold nan
