Long-circulating poly(ethylene glycol)-poly(D,L-lactide) block copolymer micelles with modulated surface charge.
TLDR
It is demonstrated that a surface-modulated PEG-PDLLA micelle with a suitable size and a narrowly distributed nature has promising potential as a long-circulating carrier system with desirable biocompatibility and biofunctionality.About:

Principles of nanoparticle design for overcoming biological barriers to drug delivery
TL;DR: By successively addressing each of the biological barriers that a particle encounters upon intravenous administration, innovative design features can be rationally incorporated that will create a new generation of nanotherapeutics, realizing a paradigmatic shift in nanoparticle-based drug delivery.
Journal ArticleDOI
Factors Affecting the Clearance and Biodistribution of Polymeric Nanoparticles
TL;DR: These factors have been shown to substantially affect the biodistribution and blood circulation half-life of circulating nanoparticles by reducing the level of nonspecific uptake, delaying opsonization, and increasing the extent of tissue specific accumulation.
Journal Article
Factors Affecting the Clearance and Biodistribution of Polymeric Nanoparticles
TL;DR: In this article, the authors discuss the factors which can influence nanoparticle blood residence time and organ specific accumulation, including interactions with biological barriers and tunable nanoparticle parameters, such as composition, size, core properties, surface modifications (pegylation and surface charge), and targeting ligand functionalization.
Journal ArticleDOI
Cancer Nanotechnology: The impact of passive and active targeting in the era of modern cancer biology
TL;DR: The fundamental concepts of enhanced permeability and retention effect (EPR) are revisited and the mechanisms proposed to enhance preferential "retention" in the tumor, whether using active targeting of nanoparticles, binding of drugs to their tumoral targets or the presence of tumor associated macrophages are explored.

A New Concept for Macromolecular Therapeutics in Cancer Chemotherapy: Mechanism of Tumoritropic Accumulation of Proteins and the Antitumor Agent Smancs
Yasuhiro Matsumura,Hiroshi Maeda +1 more
TL;DR: It is speculated that the tumoritropic accumulation of smancs and other proteins resulted because of the hypervasculature, an enhanced permeability to even macromolecules, and little recovery through either blood vessels or lymphatic vessels in tumors of tumor-bearing mice.
Journal ArticleDOI
Block copolymer micelles for drug delivery: design, characterization and biological significance
TL;DR: The utility of polymeric micelles formed through the multimolecular assembly of block copolymers as novel core-shell typed colloidal carriers for drug and gene targeting and their feasibility as non-viral gene vectors is highlighted.

Biodegradable long-circulating polymeric nanospheres
Ruxandra Gref,Yoshiharu Minamitake,Maria Teresa Peracchia,Vladimir S. Trubetskoy,Vladimir P. Torchilin,Robert Langer +5 more
TL;DR: Monodisperse biodegradable nanospheres were developed from amphiphilic copolymers composed of two biocompatible blocks and exhibited dramatically increased blood circulation times and reduced liver accumulation in mice.

Amphipathic polyethyleneglycols effectively prolong the circulation time of liposomes
TL;DR: The PEG‐PE's activity to prolong the circulation time of liposomes is greater than that of the ganglioside GM1, awell‐described glycolipid with this activity.
