Filled and Sealed Porous Beads

polydisperse Chitosan-Rho gefüllte Partikel

We offer the possibility to encapsulate charged materials in porous beads. For this, we introduce these materials, such as proteins, DNA or other macromolecules into porous silica beads (Ø > 1 µm) with narrower pore size distribution, then seal the pores with a special coating and to functionalise the product, attach further polyelectrolyte layers onto the outer surface.

The confocal image shows polydisperse particles (Ø 5-10 µm) filled with Chitosan-Rho which are coated with Polyallylamine-Cy5/Polystyrolsulfonate (image size 43 µm x 43).
