PEGylated Calcium Phosphate Nanocomposites as Smart Environment‐Sensitive Carriers for siRNA Delivery

Abstract

A novel inorganic–organic hybrid nanocomposite is formed in situ using a simple and straightforward method. Conjugate of short interfering RNA (siRNA) duplex with poly(ethylene glycol) via a disulfide linkage (PEG–SS–siRNA) is demonstrated to regulate the crystal growth of calcium phosphate (CaP), yielding a monodispersed nanocomposite. The resultant nanocomposite can be utilized as nanocarriers for siRNA delivery. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
