We demonstrated successful detection of single exon in RNA fragments locked in microdroplets. The figure below shows a collection of droplets that are loaded with different RND fragments and primers to amplify a 100 bp of specific exon (Exon 9.) The obtained results demonstrated that only the targeted exon 9 can be amplified and detected by a complementary molecular beacon that gives a fluorescent signal. As a control, beacons for Exons 10 and 9A were added to the solution, but they gave no response since they were not amplified.
Hierarchically bimodal porous structures were obtained templating silica microparticles with a specially designed surfactant micelle/microemulsion mixture. We examined the dynamics of the formation of these biporous structures. In order to obtain a better understanding of the structural evolution and stability, we have performed surface tension and dynamic light scattering measurements of the surfactant/water/oil systems. These experiments provided valuable insights about the time changes of the governing parameters (surface tension, surface charge, background electrolyte concentration) and their effect on the phase state of the oil/water/surfactant system. The obtained data are correlated to the final porous structure of the silica particles.
