In this article, we have demonstrated a smart pH-modulated two-way photoswitch that can reversibly switch ion transport under alternating light exposure over wide pH range. This was prepared by functionalizing the interior of single conical glass nanochannel with poly-spiropyran-linked methacrylate (P-SPMA) polymer through surface-initiated atom transfer radical polymerization. The P-SPMA brushes comprise functional groups are responsive to and pH, which cause configuration charge changes...
Fluorescent polymers have attracted interest in many fields such as sensing, diagnostics, imaging, and organic electronic devices. Real-time techniques to monitor understand the polymerization process are important for obtaining controllable fluorescence polymers. We present a new technique situ growth of fluorescent polymer brushes by using angle-scanning based surface plasmon coupled emission (AS-SPCE) approach during electrochemically mediated atom-transfer radical polymerization. The...
The study of endocytosis, which encompasses diverse mechanisms in biology, requires the utilization high axial resolution to monitor molecular behavior on both cell surface and interior cell. We have designed a novel axially resolved fluorescence microscopic technique, termed variable-angle nanoplasmonic microscopy. proof-of-principle this approach is achieved by selectively following events vicinity membrane or use 30 nm Au-coated semitransparent coverslip as chip achieve plasmon resonance...
Energetic carriers generated by localized surface plasmon resonance (LSPR) provide an efficient way to drive chemical reactions. However, their dynamics and impact on reactions remain unknown due the challenge in observing hot holes. This makes it difficult correlate reduction oxidation half-reactions involving electrons holes, respectively. Here we detect holes form, Ag(I), a Ag using surface-enhanced Raman scattering (SERS) of SO
Light-matter interactions have always been a fundamentally significant topic that has attracted much attention. It is important to reveal fluorophore-plasmon interaction on the nanoscale. However, as powerful investigative tool, fluorescence spectroscopy still suffers from limited spectral resolution and susceptibility interfering substances. In this work, excitation-emission synchronization-mediated surface-plasmon-coupled emission (EES-SPCE) proposed break bottleneck. By actively screening...

Early and sensitive detection of δ-aminolevulinic acid (δ-ALA) porphobilinogen (PBG) is the cornerstone diagnosis effective treatment for acute porphyria. However, at present, quantifying strategies demand multiple solvent extraction steps or chromatographic approaches to separate δ-ALA PBG prior quantification. These methods are both time-consuming laborious. Otherwise, in conventional spectrofluorimetry, overlapping spectra two analytes cause false diagnosis. To overcome this challenge, we...
Abstract Probing light−matter interactions at the nanoscale is essential for elucidation of their fundamentals and construction novel nano‐optical devices.
