Molecular interferometric imaging

open access: yesOptics Express, 2008
Common-path in-line shearing interferometry, combined with pixel-array imaging, provides a surface metrology that achieves 15 pm surface height resolution. An eighth-wave thermal oxide on silicon generates a reference wave locked in the condition of phase quadrature for phase-to-intensity conversion that makes surface height or index variations ...

Spectral imaging of the Central Molecular Zone in multiple 3-mm molecular lines [PDF]

open access: yes, 2011
We have mapped 20 molecular lines in the Central Molecular Zone (CMZ) around the Galactic Centre, emitting from 85.3 to 93.3 GHz. This work used the 22-m Mopra radio telescope in Australia, equipped with the 8-GHz bandwidth UNSW-MOPS digital filter bank,

Flow velocity quantification by exploiting the principles of the Doppler effect and magnetic particle imaging

open access: yesScientific Reports, 2021
Changes in blood flow velocity play a crucial role during pathogenesis and progression of cardiovascular diseases. Imaging techniques capable of assessing flow velocities are clinically applied but are often not accurate, quantitative, and reliable ...

Imaging isodensity contours of molecular states with STM [PDF]

open access: yes, 2017
We present an improved way for imaging the local density of states with a scanning tunneling microscope, which consists in mapping the surface topography while keeping the differential conductance (d$I$/d$V$) constant.

Direct absorption imaging of ultracold polar molecules

open access: yes, 2010
We demonstrate a scheme for direct absorption imaging of an ultracold ground-state polar molecular gas near quantum degeneracy. A challenge in imaging molecules is the lack of closed optical cycling transitions.

124-Color Super-resolution Imaging by Engineering DNA-PAINT Blinking Kinetics [PDF]

open access: yes, 2019
Optical super-resolution techniques reach unprecedented spatial resolution down to a few nanometers. However, efficient multiplexing strategies for the simultaneous detection of hundreds of molecular species are still elusive.

Submillimeter Array multiline observations of the massive star-forming region IRAS 18089-1732 [PDF]

open access: yes, 2004
Submillimeter Array (SMA) observations of the high-mass star-forming region IRAS 18089-1732 in the 1 mm and 850 $\mu$m band with 1 GHz bandwidth reveal a wealth of information.

68Ga-PSMA and 11C-Choline comparison using a tri-modality PET/CT-MRI (3.0 T) system with a dedicated shuttle

open access: yesEuropean Journal of Hybrid Imaging, 2018
Background The aim of this study was to prospectively compare the detection rate of 68Ga-PSMA versus 11C-Choline in men with prostate cancer with biochemical recurrence and to demonstrate the added value of a tri-modality PET/CT-MRI system.

Multi-tracer and multiparametric PET imaging to detect the IDH mutation in glioma: a preclinical translational in vitro, in vivo, and ex vivo study

open access: yesCancer Imaging, 2022
Background This translational study explores multi-tracer PET imaging for the non-invasive detection of the IDH1 mutation which is a positive prognostic factor in glioma.

Development and Evaluation of 18F-IRS for Molecular Imaging Mutant EGF Receptors in NSCLC

open access: yesScientific Reports, 2017
To prepare and evaluate a new radiotracer 18F-IRS for molecular imaging mutant EGF Receptors in vitro and vivo. Uptake and efflux of 18F-IRS were performed with four NSCLC cell lines including HCC827, H1975, H358 and H520.
