Nanoparticles dispersed in liquid are known to undergo Brownian motion. I feel that from time to time, two individual nanoparticles can come close enough to spaces of 1-3 nm and form transient dimers, before separating. I was wondering if there is any method to model this interaction time in terms of the concentration of nanoparticle,distance between the nanoparticles, solvent viscosity and solution temperature. Can anyone please suggest me where I should start looking for the same?

Look at the early work of Smoluchowski and collision efficiency. A lot of work was carried out in the early 1900's preceding the work by Einstein (Stokes-Einstein). Take a look at this webinar for a start (slide 33 onwards):

Thanks a lot Alan. I was actually looking for a good place to start! Really appreciate your help. :)
Take a look at this thesis: http://scholarcommons.usf.edu/cgi/viewcontent.cgi?article=2440&context=etd
and Chapter 2 by Zhang in Nanomaterial: Impacts on Cell Biology and Medicine
(Most of what you need can be viewed via Google Books here without buying the book - you'll find the references to Smoluchowski and aggregation kinetics)
