*Abstract

Currently used drug delivery systems (especially for delivery of oligo-nucleotides) involve the use of cyto-toxic complexing agents (cationic lipids and polymers). Additionally, acideic endosomes capture drugs and prevent their release to the proper target. This approach discloses the development and use of novel biodegradable polymers capable of intracellular pH alterations or related buffering actions for an effective drug/oligo-nucleotide release. Such buffers neutralize the pH of the cell and stabilize the drugs to facilitate release from the endosome to the proper part of the cell. The buffer can stand alone as an imaging agent in florescence, or radioactive dyes as well, severing as part of the greater nano systems.
