Herein, we have prepared a novel poly(amidoamine) (PAMAM) dendron-lipid hybrid nanoparticle (DLNP) as a nanocarrier for drug\/gene co-delivery and examined how the dendron generation of DLNPs impacts their cargo-carrying capabilities. DLNPs, formed by a thin-layer hydration method, were internally loaded with chemo-drugs and externally complexed with plasmids. Compared to generation 2 dendron DLNP (D2LNPs), D3LNPs demonstrated a higher drug encapsulation efficiency (31% vs 87%) and better gene complexation (minimal N\/P ratio of 20:1 vs 5:1 for complexation) due to their smaller micellar aggregation number and higher charge density, respectively. Furthermore, D3LNPs were able to avoid endocytosis and subsequent lysosomal degradation and demonstrated a higher cellular uptake than D2LNPs. As a result, D3LNPs exhibited significantly enhanced antitumor and gene transfection efficacy in comparison to D2LNPs. These findings provide design cues for engineering multifunctional dendron-based nanotherapeutic systems for effective combination cancer treatment.<\/p>\r\n<img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-318\" src=\"https:\/\/wwwtest.pharmacy.wisc.edu\/faculty\/hong-research-group\/wp-content\/uploads\/sites\/27\/bm1c00541_0008-300x115.jpeg\" alt=\"visualization of Drug\/gene co-delivery\" width=\"446\" height=\"171\" srcset=\"https:\/\/wwwtest.pharmacy.wisc.edu\/faculty\/hong-research-group\/wp-content\/uploads\/sites\/27\/bm1c00541_0008-300x115.jpeg 300w, https:\/\/wwwtest.pharmacy.wisc.edu\/faculty\/hong-research-group\/wp-content\/uploads\/sites\/27\/bm1c00541_0008-1024x392.jpeg 1024w, https:\/\/wwwtest.pharmacy.wisc.edu\/faculty\/hong-research-group\/wp-content\/uploads\/sites\/27\/bm1c00541_0008-768x294.jpeg 768w, https:\/\/wwwtest.pharmacy.wisc.edu\/faculty\/hong-research-group\/wp-content\/uploads\/sites\/27\/bm1c00541_0008-1200x459.jpeg 1200w, https:\/\/wwwtest.pharmacy.wisc.edu\/faculty\/hong-research-group\/wp-content\/uploads\/sites\/27\/bm1c00541_0008.jpeg 1254w\" sizes=\"auto, 100vw\" \/>\r\n\r\n<hr \/>\r\n\r\n<h2>Cited by<\/h2>\r\nThis article is cited by 2 publications\r\n<ol class=\"list-of-citations\" data-role=\"citations\">\r\n \t<li data-pubmed-id=\"34984833\">\r\n<div class=\"single-citation\">Poellmann, M.
