Misfolding and aggregation of nascent proteins: a novel mode of toxic cadmium action in vivo. [PDF]
, 2017 Cadmium is a highly poisonous metal and a human carcinogen, but the molecular mechanisms underlying its cellular toxicity are not fully understood. Recent findings in yeast cells indicate that cadmium exerts its deleterious effects by inducing widespread

Hemicyanines-potential heavy metal ion sensors
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The synthesis of four hemicyanine dyes are reported. Varying the donor-acceptor properties of hemicyanine dyes has a drastic influence on the aggregation properties and photophysical properties. 4-(N, N-dimethyl)amino benzaldehyde, 4-nitro benzaldehyde and 4-hydroxy benzaldehyde are used as donors.

Polyazulene based materials for heavy metal ions detection [PDF]
IOP Conference Series: Materials Science and Engineering, 2017 Azulene is a special monomer used to functionalize electrodes due to its high polarizability, because it makes possible spontaneous electron drift from the five-membered ring to the seven-membered ring. Our study concerns the electrochemical characterization by cyclic voltammetry, differential pulse-voltammetry and rotating disk electrode voltammetry ...

A modular self-assembled sensing system for heavy metal ions with tunable sensitivity and selectivity [PDF]
, 2017 Here we describe a self-assembled sensing system composed of three separate modules: gold nano particles, a reporter element, and a recognition element. The gold nanoparticles serve as a multivalent platform for the interaction with both the reporter and
