Since I am a theoretical chemist, most of my research in recent years has been in collaboration with experimental colleagues. Two recent interests are the delivery of anticancer drugs using gold nanoparticles (with Prof. Dabrowiak), and the agglomeration process, by which a collection of monomers forms higher n-mers (with Prof. Chaiken).
Gold nanoparticles are promising as drug delivery vehicles since they are nontoxic, can be ingested by cells, and loadable with drugs and substances to make them attractive to cancer cells. The size of such particles, an important consideration, is usually measured by removing a few hundred particles from the suspension medium to a grid for TEM imaging and measurement. Problems: one is not measuring them in situ, and there are statistical errors. We have shown that a detailed size histogram can be obtained for the particles in situ by monitoring their sedimentation using a simple absorption spectrometer, if absorption is measured at several wave lengths. Differences between the suspended particles and those in the TEM become apparent.
Agglomeration may be described by the Smoluchowski equations, which assume only 2nd-order reactions of m-mer and n-mer to form an (m+n)-mer. Starting from monomers only, one can preeict the asymptotic (long-time) size distribution. To apply the equations to agglomeration in a nozzle-beam expansion, for which detailed experimental results are available, we had to modify them because the temperature and the volume occupied by the particles are time-dependent. From the modified equations, we made predictions about the size distributions as a function of time, and the predictions agreed with measured results for H2 agglomeration.
