Customizing 3D Hierarchically Macroporous Covalent Organic Framework Superstructures for Improved Biosensing Interface in Highly‐Sensitive Electrochemical Biosensors

Exploration, EarlyView.
The 3D hierarchically macroporous COF superstructure, which demonstrates enhanced mass and charge transfer along with superior substrate enrichment at the biosensing interface, serves as an advanced electrode material for enzyme immobilization.

Antarctic soil microbiomes encode structurally conserved and phylogenetically diverse beta‐lactamases

iMetaOmics, EarlyView.
An integrative metagenomic framework combining sequence, structural, and functional inference reveals a phylogenetically diverse and structurally conserved repertoire of putative beta‐lactamases across Antarctic soil microbiomes, with predominance of class A and subclass B3 enzymes and limited but detectable associations with mobile genetic elements ...

Aqueous synthesis of CdTe quantum dot as biological fluorescent probe for monitoring methyl parathion by fluoro-immunosensor [PDF]

, 2009
Bioconjugation of quantum dots (QDs) provide high resolution in biological fluorescent labelling as a result of physical and optical properties of QDs. This intrinsic property of QDs can be made use of for sensitive detection of target analytes including

Presence of oOrganophosphate Insecticides in fish of the Amazon River [PDF]

Acta Amazonica, 2003
Trace levels of three organophosphate insecticides (OPI) were detected in eight fish species from the region of Santarém, State of Pará, Brazil. Individual concentrations of OPI in fish ranged from less than the detection limit to 2,1 ppb.

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from
