What is the difference between nanoparticles and quantum dots

The smaller chloride ion causes the color of the solution to change from red to blue. Quantum dots are of much interest for the other other unusual properties that they possess.

These other properties include electrical and nonlinear optical properties. These unique properties of nano sized particles are partly the result of the unusually high surface to volume ratios for there particles, as many as one-third of the atoms are on the surface of the particle. These quantum electrical properties make these quantum dots of particular interest in the electronics industry.

There small size means that electrons do not have to travel as far as with larger particles, thus electronic devices can operate faster. Quantum dots can emit light if excited, the smaller the dot, the higher the energy of the emitted light.

This ability to create dots that emit a rainbow of colors suggest that they could be used as biosensors. Unlike the dyes currently being used as biosensors, quantum dots do not degrade as rapidly.

It is possible to make light-emitting diodes LEDs from quantum dots. They may also be used to emit white light for backlighting laptop computer screens. There is also great promise for using quantum dots in other solid state electronic devices. Quantum dots may some day be used as lasers. Cancer develops when abnormal cells in the body begin to grow and spread very fast.

These bad cancer cells are often not that different from healthy cells, which makes cancer treatment difficult. Most cancer treatments kill some of the healthy cells along with the bad cells, making patients sick. What if you could design a treatment that would only target the cancer cells and leave the healthy cells untouched?
