Optical steering of microbubbles for nanoparticle transport

Abstract: Electrical and Computer Engineering, University of Dayton, Dayton, OH 45469 ------------------------------------------------------------------------***----------------------------------------------------------------------Abstract In this research, optical manipulation of microbubbles, and microbubbles coated with metallic nanoparticles, is investigated, both theoretically and experimentally. First, an equivalent force model on a microbubble by a focused optical beam is developed, starting from the force on a single induced dipole. This is extended to the case of microbubbles coated with metallic nanoparticles. Theoretical predictions are compared with experimental results. A focused laser beam, introduced in the vicinity of microbubbles of different sizes, attracts the microbubbles. The average velocities of these microbubbles can be related to the force imparted by the laser beam. Laser steering of the microbubbles is also experimentally demonstrated. It is shown that nanoparticles have a negligible effect on the manipulation of nanoparticle-surrounded microbubbles.

Problems and prospects application of silver nanoparticles in medical practice

Abstract: At the end of 80-years of the last century into scientific terminology introduce a family of new terms with prefix «nano» as: nanotechnology, nanostructure, nanocompocitematerial, nanocluster, nanochemistry, nanophysics, nanobiotechnology and etc. In all over countries there were editions, journals where published results devoted exclusively to nanomaterials[

Nanomaterial-mediated low-temperature photothermal therapy via heat shock protein inhibition

Abstract: With the continuous development of nanobiotechnology in recent years, combining photothermal materials with nanotechnology for tumor photothermal therapy (PTT) has drawn many attentions nanomedicine research. Although nanomaterial-mediated PTT is more specific and targeted than traditional treatment modalities, hyperthermia can also damage normal cells. Therefore, researchers have proposed the concept of low-temperature PTT, in which the expression of heat shock proteins (HSPs) is inhibited. In this article, the research strategies proposed in recent years based on the inhibition of HSPs expression to achieve low-temperature PTT was reviewed. Folowing this, the synthesis, properties, and applications of these nanomaterials were introduced. In addition, we also summarized the problems of nanomaterial-mediated low-temperature PTT at this stage and provided an outlook on future research directions.
