Disclosed are biodegradable nanocarriers that have a net positive surface charge and zeta potential between about +2 to about +20 mV. The positive surface charge of the nanocarriers is provided by peptides that are covalently attached to the surface of the nanocarriers. The nanocarriers may comprise a drug and may be administered for localized and sustained delivery of the drug.
