The main goal of this paper is to demonstrate that photothermal method is an effective tool for detection of geometrical and structural non-uniformities within optically non-opaque, light scattering, planar multilayer structures. The investigated objects were plates of glass coated with silica, cellulose, aluminum oxide, polyamide or octadecylsilane. The thickness of coating ranged from 100 to ...

Molecular communication provides a direct method for interfacing living cells via transmission of chemical signals. Here we report our recent result of developing a novel molecular communication method based on the cellular event called autophagy. The method currently under investigation uses micrometer-sized objects coated with bio-reactive molecules as information carrying molecules, which ar...

cells, DNA-coated microspheres and microorganisms, is very important in life science studies and biomedical applications. In this study, acoustic radiation force in an ultrasonic standing wave field is used for micro-objects manipulation, a technique termed as acoustophoresis. Free surfaces of liquid droplets are used as sound reflectors to confine sound waves inside the droplets. Two technique...

the nylon and nylon/lycra yarns were coated with electrically conductive polymers such as polyaniline and polypyrrole, via chemical polymerization process. electrical conductivity of the coated yarns was measured at variousstrain levels using two-point probe technique and their strain sensitivities were studied. the results showed that, electrical conductivity of the coated yarns decreased with...

long-term use of indwelling medical catheters has often been hindered by catheter-associated nosocomial infections. in this study the effectiveness of silver coating of polystyrene and polyethylene polymers was investigated. polymer pieces of 2 cm2 each were coated with a thin layer of silver using electroless plating technique. silver-coated polymers were challenged with cultures of four diffe...

We consider the inverse scattering problem of determining the shape of a partially coated obstacle in R 3 from a knowledge of the incident time harmonic electromagnetic plane wave and the electric far field pattern of the scattered wave. A justification is given of the linear sampling method in this case and numerical examples are provided showing the practicality of our method. 1. Introduction...

We compare the use of two-dimensional total internal reflection fluorescence microscopy with a rapid, simple-to-implement method for three-dimensional (3D) imaging using spinning-disk confocal microscopy suitable for reliable 3D tracking of clathrin-coated endocytic and endosomal carriers. These carriers contain about 20 EGFP (enhanced green fluorescent protein) equivalents of a chimeric fluore...
