Abstract
When nanoparticles (NPs) enter a biological fluid (e.g., human plasma (HP)), proteins and other biomolecules adsorb on the surface leading to formation of a rich protein shell, referred to as "protein corona". This corona is dynamic in nature and its composition varies over time due to continuous protein association and dissociation events. Understanding the time evolution of the protein corona on the time-scales of a particle's lifetime in blood is fundamental to predict its fate in vivo. In this study, we used lipid NPs, the cationic lipid 3β-[N-(N',N'-dimethylaminoethane)-carbamoyl] (DC-Chol) and the zwitterionic lipid dioleoylphosphatidylethanolamine (DOPE), that are among the most promising nanocarriers both in vitro and in vivo. Here, we investigated the time evolution of DC-Chol-DOPE NPs upon exposure to HP. On time scales between 1 and 60 minutes, nanoliquid tandem mass spectrometry revealed that the protein corona of DC-Chol-DOPE NPs is mainly constituted of apolipoproteins (Apo A-I, Apo C-II, Apo D, and Apo E are the most enriched). Since the total apolipoprotein content is relevant, we exploited the protein corona to target PC3 prostate carcinoma cell line that expresses high levels of scavenger receptor class B type 1 receptor, which mediates the bidirectional lipid transfer between low-density lipoproteins, high-density lipoproteins, and cells. Combining laser scanning confocal microscopy experiments with flow cytometry we demonstrated that DC-Chol-DOPE/HP complexes enter PC3 cells by a receptor-mediated endocytosis mechanism.

Abstract
Nanomedicine has the potential to transform clinical care in the 21st century. However, a precise understanding of how nanomaterial design parameters such as size, shape and composition affect the mammalian immune system is a prerequisite for the realization of nanomedicine's translational promise. Herein, we make use of the recently developed Particle Replication in Non-wetting Template (PRINT) fabrication process to precisely fabricate particles across and the nano- and micro-scale with defined shapes and compositions to address the role of particle design parameters on the murine innate immune response in both in vitro and in vivo settings. We find that particles composed of either the biodegradable polymer poly(lactic-co-glycolic acid) (PLGA) or the biocompatible polymer polyethylene glycol (PEG) do not cause release of pro-inflammatory cytokines nor inflammasome activation in bone marrow-derived macrophages. When instilled into the lungs of mice, particle composition and size can augment the number and type of innate immune cells recruited to the lungs without triggering inflammatory responses as assayed by cytokine release and histopathology. Smaller particles (80×320 nm) are more readily taken up in vivo by monocytes and macrophages than larger particles (6 µm diameter), yet particles of all tested sizes remained in the lungs for up to 7 days without clearance or triggering of host immunity. These results suggest rational design of nanoparticle physical parameters can be used for sustained and localized delivery of therapeutics to the lungs.

Abstract
AbstractGold nanoparticles (GNPs) have gained in prominence within the field of nanomedicine with recent advancement of several embodiments to clinical trials. To ensure their success in the clinic it has become increasingly clear that a deeper understanding of the biological interactions of GNPs is imperative. Since the majority of GNPs are intended for systemic intravenous use, an immediate and critical biological interaction is between the blood and the GNP. Blood is composed of plasma proteins and cells. Both of these components can induce downstream effects upon interacting with GNPs that ultimately influence their medical impact. For instance, proteins from the blood can cover the GNP to create a biological identity through formation of a protein corona that is quite different from the originally synthesized GNP. Once in the bloodstream this protein coated GNP evokes both positive and negative physiological responses such as biodistribution into tissue for therapy (i.e., cancer) and toxicity or off target accumulation in the reticuloendothelial system (RES) that must be controlled for optimal use. In this review, we summarize predominantly in vitro studies of GNP interactions with blood plasma proteins and blood cells and make the case that more in vivo study is urgently needed to optimal design and control GNP use in medicine. In some cases where no specific GNP blood studies exist, we draw the readers’ attention to studies conducted with other types of nanoparticles as reference.

Abstract
Nanoengineered particles that can facilitate drug formulation and improve specificity of delivery afford exciting opportunities for improved lesion-specific therapy. Understanding and controlling the nano-bio interactions of these materials is central to future developments in this area. Mass-spectrometry-based proteomics techniques, in conjunction with other emerging technologies, are enabling novel insights into the modulation of particle surfaces by biological fluids (formation of the protein corona) and subsequent particle-induced cellular responses. In this Perspective, we summarize important recent developments using proteomics-based techniques to understand nano-bio interactions and discuss the impact of such knowledge on improving particle design.

Int J Pharm 2012; 437:264-74. [PMID: 22939965 DOI: 10.1016/j.ijpharm.2012.08.017] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2012] [Revised: 07/24/2012] [Accepted: 08/09/2012] [Indexed: 01/09/2023]
Abstract
The present study deals with the physicochemical characterization of DPPC:DPPG (9:1 molar ratio) and DPPC:DODAP (9:1 molar ratio) liposomes, and the determination of their fractal dimension in HPLC-grade water, PBS and in FBS. Light scattering techniques were used in order to extract information on the structure, morphology, size and surface charge of liposomes in an ageing study and their structural response to changes in concentration and temperature. Fluorescence spectroscopy showed that the microviscosity of cationic liposomes changed by an increase of temperature. The fractal dimension, d(f), was found equal to 1.8 for reconstituted DPPC:DPPG (9:1) and DPPC:DODAP (9:1) liposomes in aqueous media. Aggregation of reconstituted DPPC:DPPG (9:1) and DPPC:DODAP (9:1) liposomes in FBS was observed. Their fractal dimensions were 1.46 and 2.45, respectively. The first order aggregation kinetics of DPPC:DODAP (9:1) liposomes in the presence of serum proteins was determined; the aggregates of cationic liposomes with serum components remained stable during 20 days with fractal dimension 2.5. The responsiveness of cationic liposomes to changes in temperature in the three dispersion media has revealed the self-assembly and the morphological complexity of cationic vectors. Finally, we suggest that these studies could be used for developing effective advanced drug delivery nano-systems (aDDnSs) based on their fractal characteristics which effectively draw their morphological profile.
