Molecular Contrast Optical Coherence Tomography: A Review [PDF]

open access: yes, 2004
This article reviews the current state of research on the use of molecular contrast agents in optical coherence tomography (OCT) imaging techniques. After a brief discussion of the basic principle of OCT and the importance of incorporating molecular ...

Super-resolution imaging and estimation of protein copy numbers at single synapses with DNA-PAINT [PDF]

open access: yes, 2019
In the brain, the strength of each individual synapse is defined by the complement of proteins present or the "local proteome." Activity-dependent changes in synaptic strength are the result of changes in this local proteome and posttranslational protein

Imaging correlates of molecular signatures in oligodendrogliomas. [PDF]

open access: yes, 2004
Molecular subsets of oligodendroglioma behave in biologically distinct ways. Their locations in the brain, rates of growth, and responses to therapy differ with their genotypes. Retrospectively, we inquired whether allelic loss of chromosomal arms 1p and

Size-tuneable nanometric MRI contrast agents for the imaging of molecular weight dependent transport processes [PDF]

open access: yes, 2014
Purpose: To evaluate size-tuneable nanomeric glycol-chitosan-DTPA-Gd conjugates as MRI contrast agents for the imaging of molecular weight (MW) dependent transport processes.

Noninvasive depth estimation using tissue optical properties and a dual-wavelength fluorescent molecular probe in vivo [PDF]

open access: yes, 2017
Translation of fluorescence imaging using molecularly targeted imaging agents for real-time assessment of surgical margins in the operating room requires a fast and reliable method to predict tumor depth from planar optical imaging.

Molecular Imaging of the Breast

open access: yesAmerican Journal of Roentgenology, 2009
Contrast-enhanced magnetic resonance imaging (MRI), MR spectroscopy, and nuclear medicine sestamibi imaging using technetium-99m methoxyisobutyl isonitrile or positron emission tomography (PET) techniques provide information beyond that of structural imaging by displaying tumor neoangiogenesis, tumor metabolites, increased numbers of tumor cellular ...

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.

Cavity-enhanced Raman Microscopy of Individual Carbon Nanotubes [PDF]

open access: yes, 2016
Raman spectroscopy reveals chemically specific information and provides label-free insight into the molecular world. However, the signals are intrinsically weak and call for enhancement techniques.
