Application

VenPure® SF (Sodium borohydride powder) is a mild reducing agent used in the reduction of aldehydes and ketones to their corresponding alcohols. It is generally inert to other functional groups such as epoxides, esters, nitriles and lactones. Along with carboxylic acid, it forms acyloxyborohydride, which is a versatile reducing agent to reduce indoles, quinolones, imines, enamines, oximes and enamides.

Owing to its high storage capacity (10.8 mass %), sodium borohydride (NaBH(4)) is a promising hydrogen storage material. However, the temperature for hydrogen release is high (>500 °C), and reversibility of the release is unachievable under reasonable conditions. Herein, we

A new architecture for a biosensor is proposed using a glassy carbon electrode (GCE) modified with hemoglobin (Hb) and silver nanoparticles (AgNPs) encapsulated in poly(amidoamine) dendrimer (PAMAM). The biosensors were characterized using ultraviolet-visible spectroscopy, ζ-potential and cyclic voltammetry to investigate
