Investigating the Potential for Label‐Free Detection of Cell Apoptosis through Terahertz Nano‐Metasurfaces

open access: yesAdvanced Photonics Research, EarlyView.
This study demonstrates a label‐free optical method to monitor cells using a terahertz metasurface‐based biosensing platform. The obtained terahertz signal change for the cell‐contained nanoslots before and after external stimulus is analyzed in terms of transmittance and frequency shift, dynamically representing the cell apoptosis process.

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.

Antibiotic–Polycationic Peptide Conjugation as an Effective Strategy to Overcome Daptomycin Resistance

open access: yesAdvanced Therapeutics, EarlyView.
Antimicrobial resistance necessitates the development of new antibiotics with “resistance‐breaking” properties. In this study, conjugation of polycationic peptides is proven to represent a versatile strategy for the fast and affordable reactivation of daptomycin.
