recommendations! Published in 2018 at "Nano Research"

DOI: 10.1007/s12274-018-2202-x

Abstract: Dosage of chemotherapeutic drugs is a tradeoff between efficacy and side-effects. Liposomes are nanocarriers that increase therapy efficacy and minimize side-effects by delivering otherwise difficult to administer therapeutics with improved efficiency and selectivity. Still, variabilities… read more here.
