BACKGROUND The aim of this work is to investigate the structure and function of enzymes immobilised on nanomaterials. This work will allow better understanding of enzyme-nanomaterial interactions, as well as designing functional protein-nanomaterial conjugates. METHODOLOGY/PRINCIPAL FINDINGS Multiwalled carbon nanotubes (MWNTs) were functionalised with amino groups to improve solubility and b...

Carbon dots (CDs) attract a mounting interests as readily accessible, nontoxic, and relatively inexpensive carbon-based nanomaterials. This review systematically summarizes the recent developments in structural design of CDs, including internal carbon core external shell, related optical properties from singlet triplet states. Their practical applications optoelectronic devices biology are also...

in this study, we explained a nanobiosensor for dna sequence detection, featuring sequence specificity, cost efficiency, speed, and ease of use. without the need for labels or indicators, it may be ideal for the detection of biological agents. this review describes recent advances in electrochemical impedance spectroscopy (eis) with an emphasis on using nanoparticles and nanotechnology. a power...

In this study, a multi nanosensor was fabricated for the simultaneous detection of carbon dioxide, methane, ethanol, and ammonia gases, and its electrochemical response to various concentrations of these gases were investigated. In order to fabricate this multi nanosensor, in the first phase, the Graphene-Oxide/Polyaniline (GO/PANI) nanocomposite was synthesized. Chemical ...

Electrochemical sensors and biosensors have attracted considerable attention for the sensitive detection of a variety of biological and pharmaceutical compounds. Since the discovery of carbon-based nanomaterials, including carbon nanotubes, C60 and graphene, they have garnered tremendous interest for their potential in the design of high-performance electrochemical sensor platforms due to their...

We demonstrate a universal approach to extract one- and two-dimensional nanomaterials from contaminated water, which is based on a microscopic oil-water interface trapping mechanism. Results indicate that carbon nanotubes, graphene, boron nitride nanotubes, boron nitride nanosheets, and zinc oxide nanowires can be successfully extracted from contaminated water at a successful rate of nearly 100...
