Freeze-dried nanocrystals

The bonding of P EG was confirmed by gravimetry, IR and conductometric titration of carboxyl groups. Freeze-dried nanocrystals could be redispersed in water or organic solvents and showed strongly increased stability towards flocculation with polyelectrolyte. [Pg.145]

The chitosan + hydroxyapatite composite was also prepared in the form of membranes by coprecipitation, filtration, and freeze-drying. Needle-like hydroxyapatite nanocrystals with low... [Pg.227]
