This work investigates the use of spray freeze-drying (SFD) to produce protein loaded particles suitable for epidermal delivery. In the first part of the study, the effects of formulation and process conditions on particle properties are examined. Aqueous solutions of trehalose produce SFD particles
Freeze etch, Deep etching, Membrane skeleton, Spectrin We designed and built a freeze-drying device that ensures the protection of the specimens against contaminants during mounting on the cold stage of the freeze-fracture machine, transferring into the vacuum chamber and deep etching. The device c
The determination of ion concentrations within cells and sub-cellular compartments remains a difficult procedure, as the volumes to be analyzed are rather small. X-ray microanalysis is sufficiently sensitive, and has adequate resolution, to measure these concentrations. The major difficulties are re
