The most interesting thing about this seminar was learning that the powerful pulsed laser might damage the vision if not used in the way it was designed to be used. In addition to this since the pulsed laser has short width, we can image the pulse lasers are bursting like machine gun fire. Data on the repetition rate of the pulsed laser can be gathered from the target so that an analysis can be performed later.
As a non-contact processing method, laser has its unique advantages and there are lots of applications in medicine, for example: drug delivery, tumor labeling, and tumor destruction. As the research in the pulsed laser field continues developing, the application of pulsed lasers will be more and more widespread.
What I have learned from the seminar:
· Nanoparticles are tiny, in the order of a hundred nanometers in diameter. Therefore controlling the size of the nanoparticles is key for preparing setup before changing pulse number, pulse energy and repetition rate.
· Measuring the contact angles of nanofluid droplets is also a key factor in this research.
One question I would like to ask is:
How do you overcome controlling the nanoparticle size using chemical processes , since there is no control to the shape?
