A plasma-polymerized acrylonitrile (PP-AN)/ZnO nanobelt (NB) nanosensor reveals a better oxygen-sensing response than a bare ZnO NB nanosensor due to the sorption nature of the polymer. With the aid of UV light, significant response enhancements of PP-AN/ZnO NB nanosensors at low temperature have been observed since the effects of oxygen desorption/adsorption in PP-AN on the electron depletion ...
Cellular lensing and near infrared fluorescent nanosensor arrays to enable chemical efflux cytometry
Abstract Nanosensors have proven to be powerful tools monitor single cells, achieving spatiotemporal precision even at molecular level. However, there has not been way of extending this approach statistically relevant numbers living cells. Herein, we design and fabricate nanosensor array in microfluidics that addresses limitation, creating a Nanosensor Chemical Cytometry (NCC). nIR fluorescent ...
Wireless NanoSensor Networks (WNSNs) will allow novel intelligent nanomaterial-based sensors, or nanosensors, to detect new types of events at the nanoscale in a distributed fashion over extended areas. Two main characteristics are expected to guide the design of WNSNs architectures and protocols, namely, their Terahertz Band wireless communication and their nanoscale energy harvesting process....
This paper provides an in-depth view on nanosensor technology and electromagnetic communication among nanosensors. First, the state of the art in nanosensor technology is surveyed from the device perspective, by explaining the details of the architecture and components of individual nanosensors, as well as the existing manufacturing and integration techniques for nanosensor devices. Some intere...
A novel molecular imprinted sensor based on CdTe@SiO2 quantum dots (QDs) was developed for norepinephrine (NE) recognition. The molecularly imprinted polymer (MIP) on the surface of CdTe@SiO2 QDs (CdTe@SiO2@MIP) was characterized by Fourier transform infrared spectroscopy, transmission electron microscopy and fluorescence spectroscopy. The synthesized nanosensor had a distinguished selectivity ...
By using triangular silver (Ag) nanoparticle array, a localized surface plasmon resonance (LSPR) nanosensor was fabricated and shown to sense serum p53 protein in vitro, which is involved in head and neck squamous cell carcinoma (HNSCC). The nanosensor consists of a triangular Ag nanoparticles array with single particle dimension of 120 nm in-plane width and 45 nm out-of-plane height. When exam...
nanotechnology is the engineering of functional systems at the molecular scale which may exert a revolutionary impact on cancer diagnosis and therapy. nanotechnology is being applied to cancer in two broad areas: i) the development of nanovectors such as nanoparticles which can be loaded with drugs or imaging agents and then targeted to tumours, and ii) high-throughput nanosensor devices for de...
This work introduces a polymer-free optode nanosensor for ratiometric sodium imaging. Transmembrane ion dynamics are often captured by electrophysiology and calcium imaging, but sodium dyes suffer from short excitation wavelengths and poor selectivity. Optodes, optical sensors composed of a polymer matrix with embedded sensing chemistry, have been translated into nanosensors that selectively im...
Makes sense: Copper metal organic framework (MOF) nanoelectrodes are prepared by depositing copper benzene tricarboxylate MOF (HKUST-1) into open carbon nanopipettes and used for sensing hydrogen peroxide.
