The microspheres are often hygroscopic, unstable, and stable. They are also prone to recrystallization, therefore caution should be taken when choosing the initial ratio of acetylated dextran to methylprednisolone. Drug-loaded polymer microspheres are made using a technique called droplet microfluidics. The end product is a microsphere with consistent particle sizes and drug nanoparticles on the cross-sections. The prepared microspheres had a drug loading degree of 21.8-63.1 wt%, which is 40 to 450 times more than that achieved using conventional techniques. Additionally, in-droplet precipitation dramatically increased the effectiveness of drug loading. However, when the drug loading level increased, the encapsulation effectiveness declined. Microspheres' spherical shape has many advantages for research applications.

In the life sciences sector, consumables and tools are typically utilized with microspheres in drug discovery and development, clinical diagnostics, and biomedical research. The following are some important uses of microspheres in the life sciences: labels that are luminous, colorful, or fluorescent for detection.

The treatment or a specific spot is targeted while the medication release is prolonged thanks to Microspheres Market  and microcapsules. The medicine is uniformly spread, either dissolved or suspended, within microspheres, which are thought of as the matrix system. Microspheres typically appear as free-flowing particles.

Small, spherical thermoplastic microspheres are made of a polymer shell that encloses a gas. The volume of the microsphere dramatically increases when heated because the thermoplastic shell's outer layer softens and the gas inside the shell expands. The microspheres have an unexpanded particle size that spans from 10 to 32 m. When completely expanded, the microspheres can grow up to 60 times in volume or four times in diameter (Ahmed, 2004).

The arterial circulation (either systemic or specific to the target organ of interest) is injected with microspheres of a diameter that allows them to be contained in the microcirculation without rupturing during circulation (typically 15 m), after which the tissue is harvested and the quantity or concentration of microspheres is assessed. Given that the distribution of microspheres to the target organ or tissue is proportional to blood flow, the number of microspheres found inside organ fragments can be used to estimate the distribution of blood flow.
