A respiratory droplet is a small aqueous droplet produced by exhalation, consisting of saliva or mucus and other matter derived from respiratory tract surfaces. Respiratory droplets are produced naturally as a result of breathing, speaking, sneezing, coughing, or vomiting, so they are always present in our breath, but speaking and coughing ...
The lipid droplet's function is to store energy for the organism's body and is found in every type of adipocytes. They can consist of a vacuole, droplet of triglyceride, or any other blood lipid, as opposed to fat cells in between other cells in an organ. They contain a hydrophobic core and are encased in a phospholipid monolayer membrane. Due ...
The term droplet is a diminutive form of 'drop' – and as a guide is typically used for liquid particles of less than 500 μm diameter. In spray application , droplets are usually described by their perceived size (i.e., diameter) whereas the dose (or number of infective particles in the case of biopesticides ) is a function of their volume.
Acoustic droplet ejection, move of fluid drops without any physical contact by means of ultrasound; Droplet-shaped wave, casual localized solutions of the wave equation; Electrodynamic droplet deformation, liquid droplets suspended in a liquid exposed to an oscillating electric field; Electron-hole droplets, condensed phase of excitons in ...
The type of mask that is effective against airborne transmission is dependent on the size of the particles. While fluid-resistant surgical masks prevent large droplet inhalation, smaller particles which form aerosols require a higher level of protection with filtration masks rated at N95 (US) or FFP3 (EU) required.

Coacervate droplets dispersed in a dilute phase. Coacervate (/ k oʊ ə ˈ s ɜːr v ə t / or / k oʊ ˈ æ s ər v eɪ t /) is an aqueous phase rich in macromolecules such as synthetic polymers, proteins or nucleic acids.
These droplets are driven by the accumulation of macromolecules, producing a distinct dense phase liquid droplet within a more dilute liquid medium. [7] These droplets can propagate, retaining their internal composition, through shear forces and turbulence in the medium, and could have acted as a means of replicating encapsulation for an early ...
In non-adipocytes, lipid storage, lipid droplet synthesis and lipid droplet growth can be induced by various stimuli including growth factors, long-chain unsaturated fatty acids (including oleic acid and arachidonic acid), oxidative stress and inflammatory stimuli such bacterial lipopolysaccharides, various microbial pathogens, platelet ...
