Label-free ultra-sensitive visualization of structure below the diffraction resolution limit
(Wiley, 2018-03-23)
For both fundamental study of biological processes and early diagnosis of diseases, information about nanoscale changes in tissue and cell structure is crucial. Nowadays, almost all currently known nanoscopy methods rely ...
Simultaneous en-face imaging of multiple layers with multiple reference optical coherence tomography
(Society of Photo-optical Instrumentation Engineers, 2017-08-22)
A technique based on multiple reference optical coherence tomography (MR-OCT) is proposed for simultaneous imaging at multiple depths. The technique has been validated by imaging a reference sample and a fingerprint in-vivo. ...
Three-dimensional depth-resolved and extended-resolution micro-particle characterization by holographic light scattering spectroscopy
(Optica, 2010)
Fourier-holographic light scattering spectroscopy is applied to record complex angular scattering spectra of two- and three-dimensional samples over a wide field of view. We introduce a computational depth sectioning ...
Real-time quantitative visualization of 3D structural information
(Optica, 2012)
We demonstrate a novel approach for the real time visualization and quantification of the 3D spatial frequencies in an image domain. Our approach is based on the spectral encoding of spatial frequency principle and permits ...
Spectral encoding of spatial frequency approach for characterization of nanoscale structures
(American Institute of Physics, 2012-07-17)
An approach to acquire axial structural information at nanoscale is demonstrated. It is based on spectral encoding of spatial frequency principle to reconstruct the structural information about the axial profile of the ...
Feasibility of correlation mapping optical coherence tomography angiographic technique using a 200 kHz vertical-cavity surface-emitting laser source for in vivo microcirculation imaging applications
(Optica, 2018-08-01)
Optical coherence tomography (OCT) angiography is a well-established in vivo imaging technique to assess the overall vascular morphology of tissues and is an emerging field of research for the assessment of blood flow ...
Functional imaging for regenerative medicine
(BMC, 2016-04-19)
In vivo imaging is a platform technology with the power to put function in its natural structural context. With the drive to translate stem cell therapies into pre-clinical and clinical trials, early selection of the right ...
Arsenic in groundwater in south west Ireland: Occurrence, controls, and hydrochemistry
(Frontiers Media, 2018-12-18)
Globally numerous regions have been identified with elevated arsenic within groundwater which can result in potential adverse health risks. In Ireland, a previous national-scale research assessment of groundwater identified ...
Inhibition of human BK polyomavirus replication by small noncoding RNAs
(American Society for Microbiology Journals, 2011)
Small noncoding RNAs regulate a variety of cellular processes, including genomic imprinting, chromatin remodeling, replication, transcription, and translation. Here, we report small replication-regulating RNAs (srRNAs) ...
Electrothermal equivalent three-dimensional finite-element model of a single neuron
(Institute of Electrical and Electronics Engineers, 2017-09-14)
Objective: We propose a novel approach for modelling the interdependence of electrical and mechanical phenomena in nervous cells, by using electrothermal equivalences in finite element (FE) analysis so that existing ...
