Quantum dot imaging for embryonic stem cells
This section provides a good summary of what the article is about. Essentially researchers used several different quantum dots (very small particles that emit light when exposed to an excitation wavelength) to visualize several colors in ES cells using only one wavelength. Researchers hope that these quantum dots will provide a better non-toxic way of following cells as they develop in an embryo (lineage tracing) without damaging or altering the cells.
To understand the significance of lineage testing and the limitations of current techniques. This information can be found in the introduction.
Compared to other imaging techniques currently used in live tissues (such as dyes and fluorescent proteins), quantum dots are incredibly small (less likely to interfer with the normal processes in the cell), have a wide range of excitation spectra with both broad and ...

Nano Wire Problem
Given a Nanowire with cross sectional dimensions of 10 nm x 10 nm, what momentum would an
electron in the ground state need in order to possess the same energy as a stationary electron
(zero momentum) in the n=1,2 state?
Note that, when it says n=1,2 it means nx=1 and ny=2... In reality its not that restrictive, but it was pointed out to me that the wording was confusing. I am not looking for two solutions, one for n=1 and one for n=2. This is a problem dealing with a mixed system where two dimensions are governed by quantum mechanics and the third by classical.
I need the step-by-step solution please.View Full Posting Details
