Interaction of Oligonucleotides with Gold Nanoparticles: Factors Beyond Electrostatic and Van‐Der Waals Forces

open access: yesAdvanced Materials Interfaces, EarlyView.
The formation of stable clusters of gold nanoparticles with oligonucleotides at different solution conditions is explored. DNA base homogeneity and strand directionality influence the binding with gold nanoparticles leading to interesting clustering behavior that can be relevant for SERS applications.

Organic Transistor‐Based Biosensors for Viral RNA Detection and Variant Monitoring: From SARS‐CoV‐2 to Effective Management of Future Pandemics

open access: yesAdvanced Sensor Research, EarlyView.
A novel approach for direct sensing of viral RNA is proposed, allowing PCR‐free detection of viral RNA from genomic material, and variants screening by discrimination of polymorphic amplicons. The device is a cost‐effective, user‐friendly platform suitable for both mass screening kits and as a laboratory tool for an optimized management of resources ...

Modulating Signal Generation in Aptamer‐Based CNT‐FET Biosensors by Controlling the Functionalization Route

open access: yesAdvanced Sensor Research, EarlyView.
The impact of different assembly strategies is discussed on the performance of nanoscale aptamer‐based SWCNT‐FET biosensors. By combining electrical and optical characterization, this is revealed that how aptamer conformation affects local electrostatic changes within the Debye length, leading to distinct sensor responses.

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.
