A nanoplatform-based aptasensor to electrochemically detect epinephrine produced by living cells.

A novel aptasensor has been designed for quantitative monitoring of epinephrine (EP) based on cerium metal-organic framework (CeMOF) loaded gold nanoparticles (AuNPs). The aptamer, specific to EP, is immobilized on a flexible screen-printed electrode modified with AuNPs@CeMOF, enabling highly selective binding to the target biomolecule. Under optimized operational conditions, the peak currents using voltammetric detection measured at voltage of 83 mV (vs.

CdS/TiC heterostructure-based photoelectrochemical platform for sensitive and selective detection of trace amount of Cu.

Photoelectrochemical (PEC) detection as a potential development strategy for Cu ion sensor has arisen extensive attention. Herein, CdS/TiC heterostructure was synthesized by electrostatically driven assembly and hydrothermal method. On the basis of a CdS/TiC heterostructure, a novel anodic PEC sensing platform was constructed for highly sensitive detection of trace amount of Cu.

Gas environment independent temperature sensor via double-metal surface plasmon resonance.

As the sensitivity of the optical temperature sensor increases, one of the most important noise sources may be from the fluctuation of the surrounding gas environment (refractive index change). In this work, we have designed and fabricated an optical temperature sensor with a device size of 15 μm. The sensor is constructed by a titanium dioxide grating on top of a double-metal surface plasmon resonance (SPR) structure.

N-(2,4-Dichloro-phen-yl)-1,3-thia-zol-2-amine.

In the title mol-ecule, C(9)H(6)Cl(2)N(2)S, the mean planes of the benzene and thia-zole rings make a dihedral angle of 54.18 (8)°. In the crystal, mol-ecules are joined into dimers with an R(2) (2)(8) ring motif by pairs of N-H⋯N hydrogen bonds.
