Topic: Cerasomes: A New Family of Bio-nano Hybrid Materials
Speaker: Prof. Jun-ichi Kikuchi
Date: November 5(Tuesday), 3 p.m.
Location: Room 301, Founder Building
Host: Zhifei Dai
Structural and functional hybridization of a biomolecule with another chemical component has been often adopted for design of advanced nanomaterials. Along this line, we have recently developed the cerasome, a liposomal membrane having a ceramic surface, as a novel organic-inorganic hybrid material. Owing to its extremely high morphological stability as compared with the conventional liposomes, the cerasome performs as an excellent biomembrane model to construct artificial multi-cellular systems. We have also revealed that the cationic cerasome can be used as an infusible and cell-friendly gene carrier. In order to break fresh ground for the cerasomes as the nanohybrid materials, we have prepared the metallosome, a metal-coated liposome, by employing electroless plating technique toward the cerasomes. In addition, functionalization of the cerasome surface by introducing titania or hydroxyapatite has been achieved. In this presentation, I will introduce design, preparation, characterization and functionalization of cerasomes as a versatile bio-nano hybrid material.
