Highly sensitive nonenzymetic glucose sensing based on multicomponent hierarchical NiCo-LDH/CCCH/CuF nanostructures

In situ microfluidic fabrication of SERS nanostructures for highly sensitive fingerprint microfluidic-SERS sensing

A microfluidic device with integrated silver nanoparticles (AgNPs) was fabricated via in situ galvanic replacement of a pre-patterned copper substrate in a microfluidic channel. The integrated microfluidic device with AgNPs serves as a highly active Raman substrate which can be applied for in-channel surface-enhanced Raman scattering (SERS). Preparation of the SERS active substrate and subseque...

Sensitive electrochemical nonenzymatic glucose sensing based on anodized CuO nanowires on three-dimensional porous copper foam

In this work, we proposed to utilize three-dimensional porous copper foam (CF) as conductive substrate and precursor of in-situ growth CuO nanowires (NWs) for fabricating electrochemical nonenzymatic glucose sensors. The CF supplied high surface area due to its unique three-dimensional porous foam structure, and thus resulted in high sensitivity for glucose detection. The CuO NWs/CF based nonen...

Design and Simulation of a New Highly Sensitive Gas Sensor Based on Negative Refraction Photonic Crystal

In this paper, design and simulation of a new highly sensitive gas sensor based on a hybrid photonic crystal (PC) structure, containing negative and positive refractive index sections, is presented. It has been shown that using a PC with negative refraction in the first section, the transmitted power is concentrated on the entrance of the sensing channel, and the transmission of the proposed se...

Superomniphobic, transparent, and antireflection surfaces based on hierarchical nanostructures.

Optical surfaces that can repel both water and oil have much potential for applications in a diverse array of technologies including self-cleaning solar panels, anti-icing windows and windshields for automobiles and aircrafts, low-drag surfaces, and antismudge touch screens. By exploiting a hierarchical geometry made of two-tier nanostructures, primary nanopillars of length scale ∼ 100-200 nm s...
