TLDR
An understanding of how synthetic and natural chemical moieties on the nanoparticle surface (in addition to nanoparticle shape and size) impact their interaction with lipid bilayers and cells is presented.
Abstract
The interaction of nanomaterials with cells and lipid bilayers is critical in many applications such as phototherapy, imaging, and drug/gene delivery. These applications require a firm control over nanoparticle-cell interactions, which are mainly dictated by surface properties of nanoparticles. This critical Review presents an understanding of how synthetic and natural chemical moieties on the nanoparticle surface (in addition to nanoparticle shape and size) impact their interaction with lipid bilayers and cells. Challenges for undertaking a systematic study to elucidate nanoparticle-cell interactions are also discussed.

Facile Peptides Functionalization of Lanthanide-Based Nanocrystals through Phosphorylation Tethering for Efficient in Vivo NIR-to-NIR Bioimaging.

TL;DR: It is shown that noncovalent surface engineering based on ligand exchange of peptide for lanthanide based upconversion and downconversion near-infrared (NIR) luminescent nanoparticles can be efficiently realized by modifying the hydroxyl functional group of a side grafted serine of peptides into a phosphate group (phosphorylation).

On the effect of ligand shell heterogeneity on nanoparticle/protein binding thermodynamics.

TL;DR: An analytical ultracentrifugation (AUC) based method to determine NP/protein binding thermodynamic parameters is used to investigate the binding parameters for a well-defined set of gold NPs with varying size and surface ligand ratios to the model protein human serum albumin and finds that gold NBP with a homogenous distribution of hydrophilic molecules in their ligand shell have a monotonic dependence of their binding constants.

Bioactivity of nanosilver in Caenorhabditis elegans: Effects of size, coat, and shape

TL;DR: The authors' findings in Caenorhabditis elegans correlate well with findings in rodents for AgNP size vs. uptake and toxicity, as well as for induction of immune effectors, while using methods that are faster and far less expensive, supporting the use of C. elegans as an alternative model for early toxicity screening.

Direct gene transfer into mouse muscle in vivo.

TL;DR: RNA and DNA expression vectors containing genes for chloramphenicol acetyltransferase, luciferase, and beta-galactosidase were separately injected into mouse skeletal muscle in vivo and expression was comparable to that obtained from fibroblasts transfected in vitro under optimal conditions.

Regulated portals of entry into the cell

TL;DR: ‘Endocytosis’ encompasses several diverse mechanisms by which cells internalize macromolecules and particles into transport vesicles derived from the plasma membrane and must be viewed in a broader context than simple vesicular trafficking.
