Single‐Layer Radially Compartmentalized Paper Chip (RCP‐Chip) for Rapid Isothermal Multiplex Detection of SARS‐CoV‐2 Gene Targets

open access: yesAdvanced Sensor Research, EarlyView.
The single‐layer RCP‐Chip enables rapid, multiplexed detection of SARS‐CoV‐2 RNA using RT‐LAMP and gold nanoparticle‐enhanced colorimetric readouts. After sample loading, amplification occurs within radially arranged chambers, allowing simultaneous detection of E and N genes.

Selective Co‐Assembly of Water‐Soluble Conjugated Polyelectrolyte with Discernable Fluorescence Modulation for Antibiotic Detection

open access: yesAdvanced Sensor Research, EarlyView.
PQx‐Ph, a water‐soluble conjugated polyelectrolyte, enables rapid and selective fluorescence‐based detection of structurally distinct antibiotics via supramolecular assembly modulation. It achieves nanomolar sensitivity under mild conditions and preserves reliable sensing performance across NOM‐rich and biologically relevant water matrices, supporting ...

Chitosan, Gelatine, and Cellulose Based Hydrogels for the Removal of Potentially Toxic Elements from Aquaculture Water: A Comparative Study

open access: yesAdvanced Sustainable Systems, EarlyView.
Hydrogels made of chemically modified biopolymers are easy to prepare and cost‐effective, they have proven to be effective materials for the simultaneous removal of seven potentially toxic elements (PTEs) from ultrapure and real water samples. The cellulose‐based one seems the best for single treatments while the gelatine‐based one seems the most ...

Agrifood safety standards, market power and consumer misperceptions [PDF]

open access: yes
This paper analyzes how the implementation of a food safety standard affects firms strategic behaviour within the context of a food chain. We provide a formal analysis, which considers that the sanitary risk results from a strong heterogeneity of ...

Microbiological evaluation of sugarcane juice sold at street stands and juice handling conditions in São Carlos, São Paulo, Brazil

open access: yesCadernos de Saúde Pública
Fresh sugarcane juice is sold by street vendors without any heat treatment in São Carlos, São Paulo, Brazil. Twenty-four samples of point-of-sale juice were tested by standard methods to determine heterotrophic bacteria, total and thermo-tolerant ...
