Manipulation of biological cells by acoustic radiation forces is often motivated by its improved biocompatibility relative to alternative available methods. On the other hand, it is well known that acoustic exposure is capable of causing damage to tissue or cells, primarily due to heating or cavitation effects. Therefore, it is important to define safety guidelines for the design and operation ...

Purely organic nanoparticles based on a BODIPY dimer, BDY-NPs, have been prepared for the first time using a nanoprecipitation procedure. The fluorescent nanoparticles have high physical homogeneity, good stability in water, and low cytotoxicity, which are suitable for cell imaging.

PURPOSE The principle of guided tissue and bone regeneration has long been established for treating bone and periodontal defects. In addition to nonabsorbable barriers, various collagens have become accepted as membrane materials for separating the graft from soft tissue. However, collagen membranes differ significantly in their barrier function and biocompatibility. The objective of this pilot...

When blood contacts the surface of a material, several processes take place including the activation of coagulation and immune systems. The aim of this work is to study in vitro the biological reactions seen from the point of view ofhemocompatibility and cytocompatibility of a new polymer suggested as an artificial surface for cardiovascular applications: CarbofiJm® coated polyetherimide (C®PEI...

DEDICATION To Behnaz H. Zaribaf, who has supported me unconditionally and never gave up on me.

in this work, we report the effect of biopolymers (starch and gelatin) on in vitro biocompatibility property of nano hydroxyapatite (nhap) composites. cell culture and mtt assays were performed for in vitro biocompatibility. they show that nhap can affect the proliferation of cells and the nhap-starch and nhap-gelatin biocomposites have no negative effect on the cell morphology, viability and p...
