Microparticles advantages

In principle, there is no upper bound in measurements of particle velocity (or stress) using laser velocity interferometry. In practice, very high-pressure shock fronts can cause copious jetting of microparticles from the free surface (Asay et al., 1976), obscuring the surface from the laser beam. To alleviate this, optically transparent materials can be bonded to the specimen, and particle velocity measurements are then made at the specimen/window interface. This has the added advantage of simulating in situ particle velocity... 

As mentioned earlier, the contact-mechanics-based experimental studies of interfacial adhesion primarily include (1) direct measurements of surface and interfacial energies of polymers and self-assembled monolayers (2) quantitative studies on the role of interfacial coupling agents in the adhesion of elastomers (3) adhesion of microparticles on surfaces and (4) adhesion of viscoelastic polymer particles. In these studies, a variety of experimental tools have been employed by different researchers. Each one of these tools offers certain advantages over the others. These experimental studies are reviewed in Section 4. 

Another application of microparticle technology is the production of polymeric microspheres, which are usually produced by emulsion polymerization techniques. But a variety of polymer colloids can be made by aerosol techniques (Partch et al, 1983 Nakamura et al, 1984 Partch et al, 1985). One advantage of the aerosol route is that larger sizes can be attained... 

A benefit of FC over AVC/PTA or ELISA methods is the ability to measure more than one marker simultaneously. This can be exploited not only in the area of MP population selection but also in protocols concerned with the interaction of EMPs with other cells. In this regard, new studies exploring the interaction of EMPs with leukocytes and platelets have exploited one of FC s major advantages over other methods the ability to quantify MP cellular complexes [67, 93, 94], Similar methodologies have been employed with platelet microparticles (PMPs) or LMPs with great success and have contributed much of what we know about MPs functional aspects [34]. The approach of these assays is reasonably straightforward and may one day be used for clinical testing.
