Drug delivery is a very complex phenomenon. Most of the drugs are soluble in the water and flow easily in the body. However, drugs consisted of complex organics crystallize in different morphologies such as needles, plates, dendrites and organized lamellars. We have observed that 3.methoxy 4-hydroxybenzaldehyde also known as “vanillin” forms needles and plate morphologies in very small difference of pH or organic impurities and can crystallize in different forms. We have performed extensive studies to understand the crystallization of binary and ternary complex organic materials systems to understand the crystallization and morphologies. We will present the results of non-water-soluble organics using melt methods and discuss the mechanism of formation of different morphologies. More specifically results of 3.methoxy 4-hydroxybenzaldehyde-m.dinitrobenzene and 8- hydroxyquinoline-succinonitrile, systems will be discussed.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
