We present a high-throughput strategy for sensitive detection of H2S by using individual spherical Au–Ag core–shell plasmonic nanoparticles (PNPs) as molecular probes. This method is based on quantification color variation the single PNPs resulting from formation Ag2S particle surface. The spectral response range 51 nm PNP was specifically designed to match most region cameras. A high density immobilized and rapid RGB (red/green/blue) analysis allow large number be monitored simultaneously,...
Single-molecule photocatalysis at defects in 2D layered materials display distinct dynamic features.
Nanoconfinement imposes physical constraints and chemical effects on reactivity in nanoporous catalyst systems. In the present study, we lay groundwork for quantitative single-molecule measurements of environment heterogeneous catalysis nanoconfinement. Choosing hydrophobicity as an exemplary environmental factor, compared a range essential parameters oxidation reaction platinum nanoparticles (NPs) confined hydrophilic hydrophobic nanopores. Single-molecule experimental at single particle...
Real time observation of chemical reactions individual noble metal nanoparticles (MNPs) is fundamentally important to their controlled synthesis, sensing and catalysis applications. Here, with a simple high-throughput single-molecule darkfield spectral imaging technique, we demonstrate that the reaction-induced plasmonic resonance variations multiple MNPs could be monitored in parallel. Oxidation kinetics gold nanorods (AuNRs), either immobilized on glass substrate or moving freely...
Herein, we demonstrated a new optical microscopy method to selectively image small-size gold nanoparticles (GNPs) inside noisy living cells through determination of the difference between probe beam (illuminated at resonance wavelength GNPs, 532 nm) and reference 473 nm). From computer simulation single-particle imaging experiments, that GNPs with diameter 45 nm could be imaged in GNPs/cell lysates mixture by dual-wavelength (DWD) imaging. The diffusion dynamics nucleic acids functionalized...
Spectral chemical sensing with digital color analysis by using consumer imaging devices could potentially revolutionize personalized healthcare. However, samples small spectral variations often cannot be differentiated in due to the nonlinearity of appearance. In this study, we address problem exploiting image formation mechanism photography. A close examination processing pipeline emphasizes that although can represented digitally, it is still a reproducible subjective perception rather...
Intracellular transport is a fundamental process crucial for cellular function, driven by the coordinated action of motor proteins that move cargo along microtubule tracks. Traditional tracking methods primarily focus on trajectories, often overlooking rotational dynamics and their impact interactions with complex network. To address this limitation, we introduced digitally assisted single-particle (dSPT) method significantly advances angular resolution intracellular dynamics. By integrating...
We developed a novel method for counting single gold nanoparticles in free solution with flash-lamp darkfield microscopy and demonstrated that it could be applied to highly sensitive DNA hybridization detection based on target induced AuNP aggregation counts reduction.
The translational and rotational dynamics of anisotropic optical nanoprobes revealed in single particle tracking (SPT) experiments offer molecular-level information about cellular activities. Here, we report an automated high-speed multidimensional SPT system integrated with a deep learning algorithm for the 3D orientation gold nanoparticle probes living cells high localization precision (<10 nm) temporal resolution (0.9 ms), overcoming limitations under low signal-to-noise ratio (S/N)...
We have developed a high-resolution nonfluorescent imaging method based on superlocalization of gold nanorods (AuNRs). By taking advantage their anisotropic optical property the plasmonic scattering AuNRs, selective only fraction AuNRs can be achieved by rotating sample relative to linear polarized illumination under cross-polarization microscopy with high NA objective. The AuNR positions obtained from series images could then used reconstruct overall image. Two center-to-center distances 80...
