Polymer Coated Glass

I need to coat 100-300 um glass beads with an amphiphilic block copolymer. However, the hydrophilic portion of the polymer should be on the "outside", whereas the hydrophobic portion should be "in contact" with the glass beads. The problem is that the glass beads are hydrophilic in nature. I have been thinking about silanizing the surface of the glass beads to accomplish this. Any recommendations about how to do this and what polymers should i try? I'm looking to adsorb the polymer to the surface, rather than chemically attach it. Thanks.

Camera Industry

Hello, i have an idea for a completely new application for using a digital camera, which if this is technically possible, i believe could become a revolutionary product for a very specific industry. In order to see if my idea is even possible, i need to ask a question or two. I am relatively ignorant when it comes to understanding the distances of digital cameras relative to their zoom capabilities. So my question is, what is the range that can be practically and optimally achieved using the best commercially available cameras we have today? For instance, suppose there is a 2’x2’ sign with 1” letters say 500 yards away as an example, and using optical and/or digital lens(es) be able to zoom in and view and read that sign well enough that it can fill a 3”x3” screen on the camera? Am i talking science fiction here? If so, at what distances could one expect to achieve that capability? Would such a camera need a lens so large it would become impractical to use, and/or the cost be prohibitive (for example, under $1,000). I am looking to develop a product that has the capability to zoom in at these distances for a specific application. But i have no idea whether or not this is even realistic. Thanks in advance for the help.
