Nanoencapsulation
Many bioactive molecules are showing good promise during in vitro testing but end up with significant loss of activity during application in vivo. Poor solubility, degradation by environmental conditions and bioelimination may contribute to this observation. Nano and microencapsulation provides a solution. The combination with suitable excipients, such as polymers and complex salts enables encapsulation, tight regulation of release and improves the stability of formulation. Moreover, nano and microencapsulation may improves the stability of very sensitive bioactive molecules. Our team is composed of experts with different scientific and engineering backgroundd: physicists, engineers, material scientists and experts in cell biology.
InoCure`s experts are here to help you to develop novel nanotechnological methods.

uSphere particles
The μSphere technology is based on electrohydrodynamic atomization, where the polymeric liquid is atomized by strong electric field. Such method enables production of small and uniform droplets resulting in uniform production of particles with size from 100nm to 10 μm. μSphere particles may serve as drug delivery vehicles.The unique feature of our μSphere products is a tunable release facilitating complex release profiles. The core/shell structure of particles protects the embedded proteins, DNA and drugs susceptible to environmental damage. Programmable release and mild immobilization of active molecules enable production of next generation drug delivery systems applicable in pharmaceutical, nutrient and tissue engineering applications.
Nano and microparticles produced by µSphere technology enable encapsulation of diverse bioactive molecules. The technology enables encapsulation to both monolithical (single phase) and multi-material (multi-phase) systems. The technology is especially useful for applications where the produced material have to be easily dispersed into various oils, creams, and powders or applied to systemic administration.

Complete encapsulation service: The samples may be also optionally characterized for drug content, release, properties (pharmacokinetics), chemical properties, biocompatibility and other. In addition, release time may be optimized to meet your specific criteria (time regulated release, pH sensitive release). |
Advanced fibers for drug delivery
The unique feature of InoCure advanced nanofibrous products is a tunable release facilitating complex release profiles. The structure of fibers protects the embedded proteins, DNA, nanoparticles and drugs susceptible to environmental damage. Programmable release and mild immobilization enable production of next generation systems with complex release profiles.
