Single-particle imaging for biosensor applications
Emerging Imaging and Sensing Technologies for Security and Defence II, 2017Current state-of-the-art technology for in-vitro diagnostics employ laboratory tests such as ELISA that consists of a multi-step test procedure and give results in analog format. Results of these tests are interpreted by the color change in a set of diluted samples in a multi-well plate.

Ultrahigh-Throughput Single-Particle Hyperspectral Imaging of Gold Nanoparticles
Analytical Chemistry, 2023Gold nanoparticles (AuNPs) have become increasingly useful in recent years for their roles in nanomedicine, cellular biology, energy storage and conversion, photocatalysis, and more. At the single-particle level, AuNPs have heterogeneous physical and chemical properties which are not resolvable in ensemble measurements.

Single-particle tracking image microscopy.
Methods in enzymology, 2003The techniques of single particle tracking (SPT) and optical force microscopy (OFM) as described above allow direct imaging of the motion of molecules in the membrane of live cells, and provide a means of controlling the movement by an almost noninvasive method.

2007
The current status of single-particle X-ray imaging - or "X-ray crystallography without need for a crystal" - is reviewed, with particular emphasis on the Stony Brook/Cornell/Berkeley single yeast cell imaging project. Two-dimensional (2D) images of a quick-frozen yeast cell have been obtained with a resolution which, if carried out in three ...

Diffractive Imaging of Single Particles
2019The computational methods and applications of diffractive (lensless) imaging are reviewed. Far-field scattering (e. g., by neutrons, electrons, light, or x-rays) by a nonperiodic localized potential is detected and the phase problem solved using iterative optimization methods, which allows a three-dimensional image of the object potential to be ...

Brightness calibrates particle size in single particle fluorescence imaging
Optics Letters, 2015This Letter provides a novel approach to quantify the particle sizes of highly bright semiconductor polymer dots (Pdots) for single-particle imaging and photobleaching studies. A quadratic dependence of single-particle brightness on particle size was determined by single-particle fluorescence imaging and intensity statistics.

Lanthanide‐Doped Upconversion Nanoparticles for Single‐Particle Imaging
ChemBioChemLanthanide‐doped upconversion nanoparticles (UCNPs) have recently demonstrated great promise in single‐particle imaging (SPI) due to their exceptional photostability and minimal background fluorescence. However, their limited brightness has posed a significant barrier to wider adoption in SPI applications.
