Molecular, labeling

This comparison of the spectroscopic properties of the different types of fluorescent reporters underlines that semiconductor QDs and upconverting nanoparticles have no analogs in the field of organic dyes. Therefore, their unique features are unrivaled. The different molecular labels detailed here each display unique advantages that can compete with some of the favorable features of QDs and upconverting phosphors such as long lifetimes in the case of MLC systems and lanthanide chelates or very narrow emission bands for lanthanide chelates beneficial for spectral multiplexing.

So far we have discussed algorithms that with the addition of more computational resources (more time slices) approach the exact answer. It is useful at this point to introduce one physically based approximation that significantly reduces the computational resources required. At the least we can have it as an option when the computational resources are limited. Another useful feature of the approximation below is the ability to solve the problem of molecular labeling and proper solvent sampling. 

The molecular labeling problem is as follows. Consider a solvated system (e.g., a protein immersed in a box of water). To compute a 5sdet path, we need to specify the initial and the final coordinate sets, Xi and Xa,. Some of the coordinates are the spatial locations of water molecules. The coordinates are required by classical mechanics, true but the exact labehng of the different water molecules creates a huge labehng degeneracy. AU the permutations of water molecules will create identical trajectories. Moreover, a shght perturbation in the solvent coordinate will create altemative trajectories that we are not interested in. Our prime interest is in the dynamics of the protein rather than the dynamics of the water molecules. 

They utilize X-ray diffraction. X-ray diffraction allows direct qualitative and quantitative phase characterization — even in multiphase regions — and no potentially perturbing additives or molecular labels are needed. Although the high photon flux of synchrotron radiation is potentially damaging to the sample [15], particular parts need only be exposed to the beam for a short period of time and as a result, radiation damage is not a problem with this method. 

Most DNA sequencing today is done essentially by the same enzymatic method conceived by Frederick Sanger in the 1970s—while DNA electrophoresis instruments and molecular labels have improved (we now use fluorescent dyes, whereas Sanger used radioactive labeling), the basic...
