[10] Polystyrene microspheres are typically used in biomedical applications due to their ability to facilitate procedures such as cell sorting and immunoprecipitation. Proteins and ligands adsorb onto polystyrene readily and permanently, which makes polystyrene microspheres suitable for medical research and biological laboratory experiments.
Particulates or atmospheric particulate matter (see below for other names) are microscopic particles of solid or liquid matter suspended in the air.The term aerosol refers to the particulate/air mixture, as opposed to the particulate matter alone, [1] though it is sometimes defined as a subset of aerosol terminology. [2]
An artificial cell, synthetic cell or minimal cell is an engineered particle that mimics one or many functions of a biological cell.Often, artificial cells are biological or polymeric membranes which enclose biologically active materials. [1]
Particles 2.5 μm or smaller in size are especially notable as they can be inhaled into the lower respiratory system, and with enough exposure, absorbed into the bloodstream. Particulate pollution can occur directly or indirectly from a number of sources including, but not limited to: agriculture, automobiles, construction, forest fires ...
(Reuters) -After lackluster spending at U.S. stores on a deals-heavy Black Friday, retailers are pulling out all the stops with steep promotions and discounts on their websites and apps to entice ...
Particulate matter (PM), also known as particulates, atmospheric particulate matter (APM), or fine particles, are microscopic solid or liquid particles suspended in a gas. [97] Aerosol is a mixture of particles and gas. Volcanoes, dust storms, forest and grassland fires, living plants, and sea spray are all sources of particles.
A hotel worker told CBS he had been closing down for the evening when he looked out the window and noticed "there was a lot of bodies lying on the ground".
