Prevention of nanoparticle aggregation during freeze-drying.
Nanoparticle formulations have been widely used in the drug delivery field. The majority of published articles dealing with nanoparticle formulations have focused on the use of freshly prepared nanoparticles, but not many deal with scale-up production of nanoparticles and their long-term preservation by freeze-drying. To date, little information is available on an effective freeze-drying proces...
متن کاملCirculating-Gas Freeze Drying
WAGMAN, JACK (U.S. Army Biological Laboratories, Frederick, Md.) AND EDWARD J. WENECK. Preservation of bacteria by circulating-gas freeze drying. Appl. Microbiol. 11:244-248. 1963.-Water-washed Serratia marcescens and Escherichia coli were freeze dried in a circulating-gas system at atmospheric pressure. This convective procedure resulted in a substantially higher survival of organisms than cou...
متن کاملFreeze-drying of Aegyptianella pullorum.
Heparinized whole blood, parasitized with Aegyptianella pullorum, was collected from 2 fowls. Buffered lactose peptone (BLP) was added v/v as a stabilizer and the mixture lyophilized in 2 ml aliquots after rapid or slow freezing. At different stages during the freeze-drying process, as well as after lyophilization and reconstitution with 1.8 ml of sterile water, samples were taken and injected ...
متن کاملOptimization of the Bioactive Compounds Content in Raspberry during Freeze-drying Using Response Surface Method
The production of high-quality freeze-dried raspberry was studied by response surface method. Two independent variables, temperature (X1) and time (X2) were determined as the most important factors affecting the final product quality estimated by the responses: total phenol (Y1), total anthocyanin (Y2), vitamin C (Y3) and total bioactive compounds (Y4) content. A two-factor central composite de...
متن کاملFreeze-drying above room temperature.
This study investigates the use of solid, organic compounds to lyophilize drugs without conventional freeze-drying equipment. The aim of the investigation is to find a pharmaceutically acceptable solvent or solvent combination that is appropriate for freeze-drying on the basis of its ability to (1) solubilize hydrophobic drugs, (2) provide a stable environment for water-sensitive compounds, (3)...
