microcapsule

(mī′krō-kăp′səl, -so͞ol)
n.
A small, sometimes microscopic capsule designed to release its contents when broken by pressure, dissolved, or melted.

Immunology
Magnetic microcapsule, see there.
 
Microbiology
An antigenic virtual layer surrounding some bacteria.
 
Therapeutics
A biohybrid device in which cells of interest (e.g., pancreatic islet cells) are encapsulated in alginate poly-l-lysine or for xenografts, simple alginate, to be delivered to a target tissue.

Microcapsules circumvent host immunity and are promising of the biohybrid “organs”, as they are easily implanted (requiring simple injection by a “standard issue” syringe), biocompatible, and achieve excellent glucose control.

Then we randomized the microcapsules and observed them at various dates of incubation confirming microcapsule stability for at least 30 days with unaltered morphology and statistically non-significant size difference (Figure 3).
In our study, the microencapsulated SGC7901 cells model can provide a TME between the tumor cells and the matrix due to the special microcapsule. When the microencapsulated SGC7901 cells were cocultivated with TAMs, we detected the expressions of MMP-2 and MMP-9 but not in microencapsulated SGC7901 cells cultured alone.

The experimental data confirm a higher water demand by increasing PCM dosage, up to 75% for the render with the maximum dosage of microcapsules (Figure 1).
During the microcapsule optimization process for the delivery of corrosion indicators and inhibitors, it was discovered during the proof-of-concept experiments for autonomous corrosion indication that it would be desirable to increase the concentration of the corrosion indicator in the microcapsule core above the value allowed by the solubility.
Much of the present microcapsule literature is concerned with encapsulation for non-aggressive and low temperature operating conditions such as fragrances.
Preparation of liquid lubricant encapsulated by organic or inorganic shell microcapsules could not only provide the advantages of fluid lubrication through the release of liquid lubricant from rupture microcapsules, but also overcome the shortcomings of external lubrication.
(1999) points out that smaller sized microcapsules have larger surface area and thinner membrane, making the core material easier to diffuse through the microcapsule membrane.
The color stability of the microcapsule with maltodextrin (CapM) improved when incorporated into a gelatin matrix, and it was particularly stable when stored under darkness.
A reinforcing effect due to the microcapsule inclusion is already reported in literature for a self-healing formulation obtained using EHA as epoxy matrix and Grubbs' first-generation catalyst and DCPD-filled microcapsules as self-healing components [3].
New York, NY, August 13, 2015 --(PR.com)-- The microcapsule or microsphere formed through the process of microencapsulation is causing many breakthrough inventions in various industries and sectors.
