Diffraction is a phenomenon related to the wave nature of light and arises when a
propagating wave comes across an obstacle. Consequently, the wave can be transformed in …

BACKGROUND Interactions between inorganic nanoparticles (NPs) are central to a wide
spectrum of physical, chemical, and biological phenomena. An understanding of these …

The techniques of optical trap** and manipulation of neutral particles by lasers provide
unique means to control the dynamics of small particles. These new experimental methods …

Cell entry of anionic nano-objects has been observed in various types of viruses and self-
assembled DNA nanostructures. Nevertheless, the physical mechanism underlying the …

Calcium orthophosphates are the main mineral constituents of bones and teeth, and there is
great interest in understanding the physical mechanisms that underlie their growth …

This article presents an overview of current research activities that center on monodispersed
colloidal spheres whose diameter falls anywhere in the range of 10 nm to 1 μm. It is …

Optical tweezers are commonly used for manipulating microscopic particles, with
applications in cell manipulation, colloid research,,, manipulation of micromachines and …

We present a method of calculating the electric charge density of glass and silica surfaces in
contact with aqueous electrolytes for two cases of practical relevance that are not amenable …

Epidemiological and clinicopathological studies, allied with pathological prion protein
(PrPSc) analysis, strongly support the hypothesis that the human prion disease new variant …

This paper describes a strategy that combines physical templating and capillary forces to
assemble monodispersed spherical colloids into uniform aggregates with well-controlled …
