Simultaneous measurement of quality factor and wavelength shift by phase shift microcavity ring down spectroscopy

open access: yes, 2012
Optical resonant microcavities with ultra high quality factors are widely used for biosensing. Until now, the primary method of detection has been based upon tracking the resonant wavelength shift as a function of biodetection events.

Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

open access: yesAdvanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Quantitative analysis of tissue oxygenation variability across anatomical landmarks in healthy individuals via near-infrared spectroscopy

open access: yesScientific Reports
Near-infrared spectroscopy (NIRS) enables noninvasive assessment of tissue oxygenation, but its broader clinical application is hindered by the absence of standardized reference values across anatomical regions.

Strigolactones shape the assembly of root-associated microbiota in response to phosphorus availability

open access: yesmSystems
Plants rely on strigolactones (SLs) to regulate their development and form symbiotic relationships with microbes as part of the adaptive phosphorus (P) efficiency strategies. However, the impact of SLs on root-associated microbial communities in response

A synergistic strategy to develop photostable and bright dyes with long Stokes shift for nanoscopy

open access: yesNature Communications, 2022
Super-resolution microscopy is a powerful tool for cellular studies but requires bright and stable fluorescent probes. Here, the authors report on a strategy to introduce quinoxaline motifs to conventional probes to make them brighter, more photostable ...
