The method for producing noble metal nanocomposites involves reducing noble metal ions (Ag, Au and Pt) on graphene oxide (GO) or carbon nanotubes (CNT) by using Artocarpus integer leaves extract as a reducing agent. As synthesized MNPs/GO and MNPs/CNT composites have been characterized using X-ray diffraction (XRD), transmission electron microscope (TEM) imaging, and energy dispersive X-ray spectroscopy (EDX). The TEM images of prepared materials showed that the nanocomposites were 1-30 nm in size with spherical nanoparticles embedded on the surface of GO and CNT. This synthetic route is easy and rapid for preparing a variety of nanocomposites. The method avoids use of toxic chemicals, and the prepared nanocomposites can be used for biosensor, fuel cell, and biomedical applications.

The present invention relates to a process for the preparation of blue-fluorescence emitting carbon dots (CDTs) from sub-bituminous tertiary high sulfur Indian coals. More particularly, the present invention relates to the production of characteristics carbon dots from low-quality Indian coals by an ultrasonic-assisted wet-chemical method. Also, the present invention provides a simple and environmentally benign method for fabrication of characteristics and size-controlled carbon dots.

This application features a method of forming a nanoporous layer. The method includes steps of reducing metal ions in a reverse micelle phase composition to form nanoparticles, removing surfactant from the composition to form clusters of the nanoparticles, dispensing the composition including the nanoparticle clusters dispersed in a liquid on a substrate, and drying to form the nanoporous layer. The nanoporous layer includes nanoparticles deposited to form a three dimensional network of irregularly shaped bodies. The nanoporous layer also includes a three dimensional network of intercluster spaces that are not occupied by the three dimensional network of irregularly shaped bodies.

In various embodiments the present disclosure provides a core/shell nanocrystal comprising a core and a shell formed on the core, wherein the core/shell nanocrystal is co-doped with at least one metal dopant and at least one trivalent cation. In some embodiments, the trivalent cation is a Group 13 element. Methods of making and using the core/shell nanocrystal are also described.

A method for forming nanoparticles includes forming a stack of alternating layers including a first material disposed between a second material. The stack of alternating layers is patterned to form pillars. A dielectric layer is conformally deposited over the pillars. The pillars are annealed in an oxygen environment to modify a shape of the first material of the alternating layers. The dielectric layer and the second material are etched selectively to the first material to form nanoparticles from the first material.

A composition is disclosed which is capable of being used for detection, comprising a noble metal nanoparticle. The inventive compositions exhibit little interaction with serum proteins while exhibiting pH-dependent adsorption onto live cell membranes. The nanoparticles of the claimed invention are capable of interacting with cell membranes, which in turn permits the advantages of nanoparticle bio-imaging to be extended to many pH dependent biological processes such as targeting acidic tumor microenvironment.
