A cryogenic, coincident fluorescence, electron, and ion beam microscope

eLife, 2022
Cryogenic electron tomography (cryo-ET) combined with subtomogram averaging, allows in situ visualization and structure determination of macromolecular complexes at subnanometre resolution.

Research on Several Inspection Methods to Determine the Sequence of Photocopying and Stamping

Journal of Forensic Science and Medicine, 2015
Determining the sequence of document production and stamping is one of the most important issues in the field of questioned document identification. In China, whether a contract or a document is legal or not, highly depends on the relationship between ...

Exploiting speckle correlations to improve the resolution of wide-field fluorescence microscopy [PDF]

, 2014
Fluorescence microscopy is indispensable in nanoscience and biological sciences. The versatility of labeling target structures with fluorescent dyes permits to visualize structure and function at a subcellular resolution with a wide field of view. Due to

Planar Airy beam light-sheet for two-photon microscopy [PDF]

, 2020
We demonstrate the first planar Airy light-sheet microscope. Fluorescence light-sheet microscopy has become the method of choice to study large biological samples with cellular or sub-cellular resolution. The propagation-invariant Airy beam enables a ten-

Instant three-color multiplane fluorescence microscopy

Biophysical Reports, 2021
One of the most widely used microscopy techniques in biology and medicine is fluorescence microscopy, offering high specificity in labeling as well as maximal sensitivity. For live-cell imaging, the ideal fluorescence microscope should offer high spatial

Fluorescence Talbot microscope using incoherent source [PDF]

Journal of Biomedical Optics, 2016
Fluorescence Talbot microscope is a scalable field-of-view (FOV) imaging platform, which takes advantage of the phase sensitivity of the self-image of a periodic structure. Such a system can maintain the microscopic resolution and extend the FOV for the whole slide (15  mm×15  mm) scanning.

A novel Ca2+ indicator for long-term tracking of intracellular calcium flux

BioTechniques, 2021
The major drawback of using Fluo-4 AM is that it requires an organic anion transporter inhibitor, such as probenecid, to prevent leakage. This can hinder the studies that require extended monitoring time and longer cellular retention.

Scanning apertureless fluorescence microscope [PDF]

, 1999
We describe a near-field apertureless fluorescence microscope, capable of imaging fluorescent latex beads with subwavelength precision. The instrument is based on a home- built tapping-mode atomic-force microscope, to which an inverted optical microscope
