Plaga
In short
PLGA is a biodegradable copolymer made from lactic acid and glycolic acid used in medical devices and drug delivery.
In plain words
It is a special type of plastic that the human body can safely break down over time. Scientists use it to carry medicine inside the body or to build scaffolds for new tissue to grow on.
A simple example
A tiny capsule made of PLGA can be injected into a patient to release cancer medication slowly over several weeks.
Why it matters
Because it dissolves naturally, it removes the need for follow-up surgeries to remove implants. Its breakdown rate can also be adjusted to match how fast a wound heals.
Easy to mix up
It is often confused with PLA (polylactic acid), which is a simpler polymer without the glycolic acid component.
