Particulate filtration

Particulate filtration is a physical separation process in which solid particles suspended in a fluid (liquid or gas) are removed using a filter medium that allows the fluid to pass but retains the particles[1][3][5][7]. This process is not mediated by a single molecule or protein, but by engineered or naturally occurring materials (such as filter membranes or porous barriers), and the separation can employ physical, mechanical, chemical, or biological principles[1][3][5]. Examples include air filters, water treatment filters, and biological filtering systems in nature and technology[4][6]. While filtration is critical for public health, engineering, and environmental control, it does not correspond to a molecular target involved in therapeutic drug action, signal transduction, or other biological pathways[1][3][5][7].
