1T-Phase molybdenum sulfide/cobalt oxide nanopillars hybrid nanostructure coupled with nitrogen-doped carbon thin-film as high efficiency electrocatalyst for oxygen evolution.

High efficient and durable catalysts are always needed to lower the kinetic barriers as well as prolong the service life associated with oxygen evolution reaction (OER). Herein, a sequential synthetic strategy is considered to prepare a hierarchical nanostructure, in which each component can be configured to achieve their full potential so that endows the resulting nanocatalyst a good overall performance. In order to realize this, well-organized cobalt oxide (CoO) nanopillars are firstly grown onto ultrathin 1T-molybdenum sulfide (1T-MoS) to obtain high surface area electrocatalyst, providing electron transfer pathways and structural stability.

Phase-Regulated Sensing Mechanism of MoS Based Nanohybrids toward Point-of-Care Prostate Cancer Diagnosis.

Alpha-methylacyl-CoA racemase (AMACR) has been proven to be consistently overexpressed in prostate cancer epitheliums, and is expected to act as a positive biomarker for the diagnosis of prostate carcinoma in clinical practice. Here, a strategy for specific determination of AMACR in real human serum by using an electrochemical microsensor system is presented. In order to implement the protocol, a self-organized nanohybrid consisting of metal nanopillars in a 2D MoS matrix is developed as material for the sensing interface.

Detection of Lysyl Oxidase-Like 2 (LOXL2), a Biomarker of Metastasis from Breast Cancers Using Human Blood Samples.

Metastasis accounts for 90% of the mortality associated with breast cancer. Upregulated expression of members of the lysyl oxidase (LOX) family of secreted copper amine oxidases catalyzes the crosslinking of collagens and elastin in the extracellular matrix. LOXs are linked to the development and metastatic progression of breast cancers.
