Biocompatible hollow and/or porous particles, microspheres or nanospheres, useful e.g. in medicine, sensor applications, biology, genetic engineering, analysis or data storage

摘要

A new biocompatible material (I), for implantation, migration or intercalation in tissues, cells or organelles, is new. A new biocompatible material (I), for implantation, migration or intercalation in tissues, cells or organelles, consists of irregular or round, non-resorbable, spherical particles, microspheres or nanospheres having a semi-permeable, permeable or porous outer shell and at least one internal hollow cavity. Alternatively the outer shell can be compact, non-porous and non-permeable; if the particles or microspheres are porous the cavities can be replaced by internal pores; and/or (I) may be resorbable for some applications.
