Need A little direction on spectrometry

[davidhere40]

I'm need some advice about spectrometry. I'm looking for a forum like this where someone could help me.

 

I'm trying to do analysis of extremely small samples of a solid... as small as possible, such as nano meters to micrometers. It doesn't really matter how the substance is analyzed as long as the device can produce consistently different results for substances that are made up of fairly different molecules or relative number of elements for example.

 

ANY IDEAS HOW I CAN GET ADVICE? I'm working on a research project but lack the knowledge about existing technology available to me.

 

As a side note... the short term goal of the project is to do extremely accurate mapping of biological neural networks and the types of connections each neuron has to another without using a microscope.

 

my email is davidhere40 at gmail.com if anyone can help me.

This sort of thing will get resolution down to microns; nanometres would be more difficult.
