How do I develop a selective epoxy to cohere to metal but not to glass?

12 December 2013 0 5K Report

Currently, silver nanoparticles are being synthesized on lithiun niobate substrates. To remove these particles (held only by electrostatic forces) requires encapsulating them in a epoxy resin. Does anyone know of a method of obtaining an epoxy that envelops the particles in the composite but will release from the substrate without damaging the lithium niobate crystal? The particles must be kept in positions relative to each other. Epoxy must also be conductive to eliminate risk of charging while imaging.

I need to image mesoporous silica nanoparticles that are in ~100 nm size and do high resolution TEM to look at mesopores. what grids should I use?

Need to image mesoporous silica nanoparticles using the TEM. Also, need high resolution TEM images to see the mesoporous structure. Kindly suggest what kind of grids to use. Thanks, Shatadru

What is the state of the drug inside solid lipid nanoparticles (SLNs)?

I am a little confuse with the mechanism of solid lipid nanoparticles (SLNs). The main point of encapsulating drugs into SLNs is because some drugs have low solubility in water. Therefore, SLNs...
