Microfilaria

Microfilaria: first-stage larva of filarial nematodes (Wuchereria bancrofti, Brugia, Loa loa, Onchocerca volvulus) circulating in blood or skin, showing nocturnal periodicity, detected by blood film or skin snip microscopy.

Microfiltration

Microfiltration is a pressure-driven membrane separation process that removes suspended particles, bacteria, and protozoan parasites from liquids or gases through porous membranes with pores of 0.1 to 10 µm.

Microfinance

Microfinance, also called microfinancing, provides small loans, savings, insurance, and money transfers to low-income households and small enterprises, a global industry serving roughly 140 million borrowers in 2018.

Microfluidic cell culture

Microfluidic cell culture is a bench technique that grows cells in microscale channels, controlling perfusion, chemical gradients, and mechanical forces beyond what Petri dishes and well plates can.

Microfluidic extensional rheometry

Microfluidic extensional rheometry measures the extensional flow properties of liquids, such as extensional viscosity and relaxation time, using miniaturized channel devices suited to low-viscosity fluids and small sample volumes.

Microfluidic model

A microfluidic model is a bench biology method in which miniature tissues are cultured in microfluidic chips whose channels, flow, and gradients control the cells' microenvironment, best known as the organ-on-a-chip.

Microfluidic paper-based analytical devices

Microfluidic paper-based analytical devices (μPADs) are cheap, disposable tests in which sample moves through paper by capillary action, introduced by George Whitesides' group at Harvard in 2007.

Microfluidic peristaltic pump

A microfluidic peristaltic pump is a valveless mechanical micropump that moves fluid through microscale channels by rhythmically squeezing pumping chambers in sequence, mimicking biological peristalsis.

Microfluidic production of double emulsions

Microfluidic production of double emulsions creates droplet-in-droplet, three-phase liquids inside micron-scale channels, one drop at a time, giving uniform size and shell thickness that bulk mixing cannot deliver.

Microfluidic rheometry

Microfluidic rheometry, also called rheometry-on-a-chip, measures fluid properties such as shear viscosity, extensional viscosity, and relaxation time in micrometer-scale channels, using microliter samples and reaching shear rates conventional rheometers cannot.

Microfluidic synthesis

Microfluidic synthesis performs chemical reactions and produces nanoscale materials inside micrometer-scale channels, where fast, precise mixing controls the size of products like quantum dots and lipid nanoparticles.

Microfluidic synthesis of lipid nanoparticles

Microfluidic synthesis of lipid nanoparticles is the formation of LNPs by combining lipid-in-ethanol and aqueous streams in micron-scale channels, where laminar-flow mixing controls particle size and encapsulation.

Microfluidics

Microfluidics is the science and technology of controlling fluids in channels tens to hundreds of micrometers wide, integrating analysis steps on a chip for biological, chemical, and medical uses.

Microform

Microform: reduced-image preservation media including microfilm, microfiche, and aperture cards. Silver-gelatin film on polyester rated 500+ years; LC still designates it a preferred preservation format.

Microform holoprosencephaly

Microform holoprosencephaly (microform HPE, HPE minor form) is the mildest holoprosencephaly-spectrum condition: subtle midline facial anomalies such as hypotelorism and single maxillary incisor with normal brain imaging, and a recurrence risk for classic HPE in offspring.

Microfoundations

Microfoundations are the requirement that a macroeconomic model's behavioral relations derive from optimizing decisions of individual agents, households, and firms, rather than correlations among aggregates.

MicroFUN

MicroFUN, the Microlensing Follow-Up Network, is a consortium of observers coordinated from Ohio State University that detects extrasolar planets by photometric monitoring of microlensing events in the Galactic Bulge.

Microgel

A microgel is a cross-linked polymer colloid particle, typically 10 to 1000 nm, that swells in response to triggers such as pH and temperature, with uses in drug delivery and 3D printing.

Microgels as model soft colloids

Microgels are submicrometer-sized hydrogel particles, covalently crosslinked polymer networks swollen by solvent, whose tunable size and softness make them model systems for soft-sphere colloid physics.

Microglia

Microglia are the resident macrophages and innate immune cells of the CNS parenchyma, discovered by Pío del Río-Hortega in 1918, of yolk sac origin, about 10–15% of glial cells, with diverse disease-associated states beyond the obsolete M1/M2 scheme.

Micrognathia

Micrognathia (mandibular hypoplasia, ICD-11 DA0E.00) is an abnormally small lower jaw causing infant feeding and breathing problems, linked to syndromes like Pierre Robin, and treated with MDO surgery.

Microgreen

Microgreens: young edible vegetable and herb seedlings harvested 7–14 days after planting at the first true leaf stage, 2–8 cm tall, nutrient-dense versus mature greens, eaten raw, with Salmonella and Listeria recall history.

Microgrid

A microgrid is a group of interconnected electrical loads and local energy resources that operates as a single controllable entity, running connected to the main grid or islanded from it.

Microhabitat (소공녀)

Microhabitat (소공녀, So-gong-nyeo) is Jeon Go-woon's 2017 South Korean debut feature drama starring Esom and Ahn Jae-hong, about a housekeeper who gives up her Seoul apartment when cigarette prices double; it won the 2018 Blue Dragon and Grand Bell Best New Director awards.
