Nidhi Saiwal, Mandeep Dahiya, Harish Dureja
BACKGROUND: Ultrasound (US) has the ever-rising role in the delivery of therapeutic agents that includes chemotherapeutic agents, proteins, and genetic material. The microbubbles are the cavitating gas bodies that act as the mediators through which the energy of relatively non-interactive pressure waves is accumulated to produce forces that can permeabilize cell membranes and disrupt the vesicles that carry the therapeutic agent. This shows that the microbubbles greatly enhance the delivery of smaller chemical agents, proteins and genetic material...

Michael Z Hu, David W DePaoli, Tanya Kuritz, Ogbemi O Omatete
BACKGROUND: Controlled self-assembly using molecules/nanoparticles as building block materials represents an important approach for nanofabrication. METHOD: We present a "bottom-up" fabrication approach to first grow a new class of inorganic (silica) long hair-like microfibrils or microwires and then to form monolithic solid pellet that contains parallel arrays of bundled microfibrils with a controlled orientation. During the sol-gel solution processing, reactive precursor species are utilized as molecular "building blocks" for the field-directed assembly growth of microfibrils driven by an electric field of pulsed direct current (dc) with controlled frequency...

Giora Rytwo
BACKGROUND: Freshwater resources will not be able to meet all requirements and water should not be considered a self-renewable, low cost resource. Thus, the needs for increased amount of water imply adopting several approaches that include intercepting and transferring water, desalination and water re-use. In all three approaches removal of turbidity and total suspended solids (TSS) is a crucial step, as one of the essential parameters limiting water quality. This paper reviews a series of patents focusing on the use of clay-polymer nanocomposites to obtain very fast and efficient turbidity and suspended solids removal in water and effluents...
