Plants exposed to cadmium (Cd) show morphological and physiological disorders. To increase our knowledge regarding Cd-induced signalling, most often the effects of acute exposure are investigated. However, this does not allow in-depth analysis of morphological effects. Therefore, we chronically exposed
A novel highly sensitive and selective electrochemical sensing system based on DNAzyme and rolling circle amplification (RCA) for the determination of Pb²⁺ was developed in the present study. Firstly, the DNAzyme catalytic strands were immobilized onto magnetic beads surface and

The use of basidiomycetes for metal removal is an alternative to traditional methods. In this, the biomass acts as a natural ionic exchanger removing metals from solution. To develop a laminar biosorbent using a basidiomycete fungus resistant to high Cd
Mesoporous silica nanotubes (MSNTs) and amine-functionalized MSNTs (NH(2)-MSNTs) have been successfully synthesized via a sol-gel route using needle-like CaCO(3) nanoparticles as inorganic templates and post-modification with 3-aminopropyltriethoxysilane. Subsequently, the preformed nanotubes were functionalized with blue fluorescent CdS quantum dots, as

The initial formation of semiconductor nanocrystals/nanoclusters, that is, nucleation in the classic literature, was examined both theoretically and experimentally. An experimental method based on determining the initial reaction rate for the formation of nanocrystals/nanoclusters with fixed size and size distribution
