“Molecular sponge” for targeted drug delivery

Researchers at the Southern Federal University (SFedU) in Rostov-on-Don have developed novel nanodimensional containers for storage, target delivery and controllable dosing of drugs.

At the core of the new system are metal-organic polymeric nanoparticles that could be likened to molecular sponge. Acting like natural sponge, they can soak up medicines, use a patient’s vascular system to take them to a destination, and then “squeeze” to release the drugs from their pores, wherever necessary.

The particles that are within 200 nanometers in size are reported to be nontoxic and biocompatible.
