Nuclear hyperpolarization is a phenomenon that can be used to improve the sensitivity of magnetic resonance molecular sensors. However, such sensors typically suffer from short hyperpolarization lifetime. Herein we report that [15N, D14]trimethylphenylammonium (TMPA) has a remarkably long spin-lattice relaxation time (1128 s, 14.1 T, 30 °C, D2O) on its 15N nuclei and achieves a long retention o...

Abstract Numerous studies suggest that modification with functional nanomaterials can enhance the electrode electrocatalytic activity, sensitivity, and selectivity of electrochemical sensors. Here, a highly sensitive cost-effective disposable non-enzymatic glucose sensor based on copper(II)/reduced graphene oxide modified screen-printed carbon is demonstrated. Facile fabrication developed sensi...

Background:In recent years, the use of chemicals in agriculture, industry, and public health has become so common that the environment is continuously contaminated by the toxic substance-like metals. Aluminum released due to anthropogenic activities such as mining and industrial uses. Aluminium has several industrial uses. The present study was designed to investigate the effect of aluminium ch...

The atricle presents modern data on the composition and role of antioxidant system in human body.The stages components (enzymatic non-enzymatic) are considered, classifications given. Its participation pathogenesis diseases progression has been proven.

Abstract Graphene is a suitable transducer for wearable sensors because of its high conductivity, large specific surface area, flexibility, and other unique considerable features. Using simple, fast galvanic pulse electrodeposition approach, nonenzymatic glucose amperometric electrode was successfully developed based on well-distributed fine Cu nanoparticles anchored the 3D structure laser-indu...
