Formation of the Platelet Plug

Formation of the Platelet Plug

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Structure and Function of Platelets

Structure and Function of Platelets

The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...

To evaluate the efficacy of these nanocages in killing cancer cells.

Main Methods:

Synthesis of mesoporous silica-shelled Janus nanocages with internal graphene.
Surface modification with polyethylene glycol (PEG) for aqueous dispersity.
Loading of doxorubicin (DOX) as a chemotherapeutic agent.
Evaluation of cytotoxicity in HeLa cells under near-infrared (NIR) irradiation.

Main Results:
