Microspheres made from highly transparent glass can perform as very high quality optical microcavities or optical microresonators. Ceramic microspheres are used primarily as grinding media. Hollow microspheres loaded with drug in their outer polymer shell were prepared by a novel emulsion solvent diffusion method and spray drying technique.
A colloid is a mixture which has particles of one phase dispersed or suspended within an other phase. The term applies only if the particles are larger than atomic dimensions but small enough to exhibit Brownian motion, with the critical size range (or particle diameter) typically ranging from nanometers (10 −9 m) to micrometers (10 −6 m).

Micromeritics is the science and technology of small particles pioneered by Joseph M. DallaValle. [1] It is thus the study of the fundamental and derived properties of individual as well as a collection of particles. The knowledge and control of the size of particles has importance in pharmacy and materials science.
In other fields, the term "artificial cell" can refer to any compartment that somewhat resembles a biological cell in size or structure, but is synthetically made, or even fully made from non-biological components. The term "artificial cell" is also used for structures with direct applications such as compartments for drug delivery.
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.

Luigi Mangione, 26, was charged with murder late Monday in the Dec. 4 shooting of UnitedHealthcare CEO Brian Thompson in New York City after police in Altoona, Pa., were called to a McDonald’s ...
The family of a man who was murdered in Londonderry have said they have been "failed by the justice system" after his killer went on the run from prison again.
The Perfect Scrambled Egg Method. I don't stray from my tried-and-true ratio, but have introduced two big changes: First, the splash of cream is replaced by a small splash of good olive oil.
