Stimuli‐responsive graphically‐encoded hydrogel microparticles, termed Novabeads, achieve rapid, enzyme‐free, multiplexed detection of biomarkers at picomolar sensitivity (LOD = 28.8 pM). Leveraging pH‐responsive signal amplification and dense bioreceptor immobilization, Novabeads yield a 35‐fold fluorescence enhancement over standard hydrogel ...

Single‐molecule fluorescence detection can become highly challenging for diluted concentrations in the picomolar range. This “low concentration barrier” is broken into and achieves quantitative detection down to 0.1 pM. Introducing a diaphragm into a standard confocal microscope and implementing fluorescence lifetime correlation spectroscopy (FLCS ...

A small‐circle scanning fluorescence correlation spectroscopy (sFCS) technique is presented using acousto‐optical laser scanning and frequency‐domain fitting. Validated with simulations and experiments, sFCS investigates cationic polyelectrolyte adsorption onto anionic nanoparticles, revealing stable complexes and size increases with polymer mass ...

Quantification of Azides on the Surface of Nanoparticles: Toward Precise Bioconjugation
Herein, two spectroscopic methods for surface azides quantification are developed. The first method is based on the ability of electron‐withdrawing ligands to quench the fluorescence of conjugated dyes, whereas the second method is more general and is based on the UV–Vis monitoring of alkyne absorbance during the click reaction.

Head‐to‐head comparison between ACQ and FRET in probing polymeric micelles
Medical nanocarriers promise precise drug delivery but are hard to monitor because common fluorescent tags often give misleading signals in complex biological systems. In our study, we directly compared two labeling strategies—an aggregation‐caused quenching (ACQ) probe (FD‐B21) and a Förster resonance energy transfer (FRET) pair (DiD/DiR)—to track ...
