Makropórusok

Makropórusok are large pores or openings found in various biological and material science contexts. In biology, the term can refer to pores in cell membranes that are significantly larger than ion channels or typical aquaporins, often involved in the passage of larger molecules or even cellular debris. These larger pores can play roles in processes like endocytosis and exocytosis, or in the transport of nutrients and waste products across cellular barriers. The exact size and function of makropórusok can vary greatly depending on the specific cell type and organism.

In materials science, makropórusok describe pores within a material that have diameters typically ranging from 50 nanometers to several micrometers. These are distinct from micropores (less than 2 nanometers) and mesopores (2 to 50 nanometers). Materials containing makropórusok often exhibit unique physical and chemical properties due to their high surface area and porosity. Applications for such materials include filtration, catalysis, drug delivery, and as scaffolds for tissue engineering. The controlled creation and manipulation of makropórusok in synthetic materials is an active area of research, aiming to tailor material performance for specific technological demands. The term itself is of Greek origin, combining "makros" (large) and "poros" (pore).
