The thrombogenic activity of POSS silanols

Area of Science:

• Biomaterials Science
• Nanotechnology
• Cell Biology

Background:

• Polyhedral oligomeric silsesquioxanes (POSS) are nanoscale cage compounds with tunable properties.
• Silanol-containing materials have demonstrated interactions with biological systems, particularly erythrocytes.
• Existing research suggests POSS compounds can function as tissue scaffolds.

Purpose of the Study:

• To investigate the in vitro interaction of POSS trisilanols with red blood cells and fibroblasts.
• To evaluate the potential of POSS trisilanols in applications related to traumatic hemorrhage and wound care.
• To assess the efficacy of specific POSS cages as tissue scaffolds for enhanced healing.

Main Methods:

• In vitro incubation of POSS trisilanols with porcine and human red blood cells (erythrocytes).
• In vitro incubation of POSS trisilanols with mouse fibroblasts.
• In vitro tissue studies utilizing i-octyltrisilanol POSS cages.

Main Results:

• POSS trisilanols exhibited interactions with erythrocytes, consistent with known silanol-containing mineral activities.
• POSS trisilanols demonstrated multifunctionality, suggesting utility in hemorrhage and wound care.
• i-octyltrisilanol POSS cages provided cellular binding sites and porosity, facilitating cellular taxis and tissue regeneration.
• Observed tissue healing rates were increased in the presence of POSS scaffolds.

Conclusions:

• POSS trisilanols possess properties suitable for advanced applications in traumatic hemorrhage and wound care.
• POSS-based materials can serve as effective tissue scaffolds, promoting cellular interaction and accelerating tissue healing.
