Imaging Molecules and Cells
Proteins provide the building blocks for multicomponent molecular units, or pathways, from which higher cellular functions emerge. These units consist of either assemblies of physically interacting proteins or dispersed biochemical activities connected by rapidly diffusing second messengers, metabolic intermediates, ions or other proteins. Genetics to identifies the proteins that constitute fun...

متن کاملImaging Strategies for Hyperpolarized Elements and Molecules
and N+ and N− are the spin populations in the lower and upper energy states, respectively, is at most on the order of 10. Because of this low polarization at thermal equilibrium, there has been a constant drive for higher field systems, improved RF coil designs, and low-noise receiver systems to raise the signal-to-noise ratio (SNR) and thereby permit increased spatial, temporal or spectral res...
متن کاملDirect absorption imaging of ultracold polar molecules
We demonstrate a scheme for direct absorption imaging of an ultracold ground-state polar molecular gas near quantum degeneracy. Imaging molecules without closed optical cycling transitions is challenging. Our technique relies on photon-shot-noise-limited absorption imaging on a strong but open bound-bound molecular transition. We present a systematic characterization of this imaging technique. ...
متن کاملImaging cold molecules on a chip.
We present the integrated imaging of cold molecules in a microchip environment. The on-chip detection is based on resonance-enhanced multiphoton ionization, which is quantum state selective and generally applicable. We demonstrate and characterize time-resolved spatial imaging and subsequently use it to analyze the effect of a phase-space manipulation sequence aimed at compressing the velocity ...
