“…The cyclopolyphosphazenes have been used in biomedical applications and play a role in human health betterment via a drug delivery technique. , This drug delivery technique has many benefits over traditional and conventional types of drug dosage systems. , The drug delivery system reduced the toxicity, improved the efficiency in the context of target tissues, and improved the health condition of the patient. − Morphology-focused carriers with uniform hollow structures need an hour to efficiently run a drug delivery system, and these materials have the potential to deliver the guest molecules in systems with minimum damage to human body cells. − Until now, polyphosphazene microspheres have been utilized for modern day drug delivery systems because they can provide the monodispersion in solutions carrying large amounts of guest molecules of the drugs. ,− The biocompatibility and biodegrability of cyclopolyphosphazene materials are well-known, and many research groups , have used these molecules as biomaterials. Liu and co-worker synthesized the highly cross-linked, mesoporous, and most importantly hollow core submicrospheres and used them as drug delivery carriers .…”
