Number of living cell in microcapsule was determined by fluorimetric quantitative [PrestoBlue.sup.5] assay.
Microcapsules are spherical, with diameters in the range of 200-1500 [micro]m, and feature a biocompatible semipermeable membrane that permits the bidirectional diffusion of nutrients, secreted therapeutic products, oxygen, and waste but prevents the passage of high-molecular-weight substances into the microcapsule.
On the other hand, it can be noticed that the sorption capacity of MC increases with the amount of Cyanex 923 used during the capsule preparation; this is a consequence of the more extractant entrapped in the microcapsule due to the higher amount of Cyanex available in the casting solution.
Then, the peptide was connected to the two popular delivery systems: a microcapsule and a profragrance model polymer.
Commercial microencapsulated PCMs (n-heptadecane) with characteristic diameter of 5 [micro]m, thickness of the shell of PMMA microcapsule equal to 0.1-0.2 [micro]m, and melting temperature equal to 23[degrees]C were used.
Microcapsule as well as is another Brucella virulence factor that plays an important role in preventing phagolysozyme integration.
The development of the encapsulation technology has progressed from the initial proof-of-concept work, in which a corrosion indicator was encapsulated into an oil-core (hydrophobic) microcapsule and shown to be delivered autonomously, under simulated corrosion conditions, to a sophisticated portfolio of micro carriers (organic, inorganic, and hybrid) that can be used to deliver a wide range of active corrosion ingredients at a rate that can be adjusted to offer immediate as well as long-term corrosion control.
The liquid paraffin encapsulating microcapsule was synthesized by in situ polymerization with melamine formaldehyde (MF) resin as wall material.
The pastilles comprise: a balancing agent selected from the group consisting of glycerin; polypropylene glycol; isopropyl myristate; dipropylene glycol; 1,2 propanediol and mixtures thereof; polyethylene glycol; and friable perfume microcapsule that comprises an encapsulated perfume.
The patented Microcapsule Technology locks in the natural benefits, allowing one to wash the pyjamas and use them again and again.
Where R is the yield of microcapsules (%), [MS.sub.dry] basis is the amount of sedimented microcapsule (g) and [MTI.sub.dry basis] the initial theoretical mass consisting of Arabic gum + gelatin + oil (g).
