Biodegradable poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles were derivatized with Tat49−57 peptide, which is the protein transduction domain from the transcriptional activator Tat protein of human immunodeficiency virus type-1 (HIV-1). The Tat49−57 peptide-modified PLGA nanoparticles, with a mean diameter of ca. 238 nm, was effectively adsorbed on to the membrane of HaCaT cells and delivered into the nuclei without cytotoxicity.
