Abstract
The protein corona is inevitably formed on nanoparticles (NPs) when they are introduced in vivo and has been associated with a reduction in targeting yield, immune recognition and rapid blood clearance, leading to poor tumor accumulation. We have recently shown that it is possible to exploit the protein corona for drug delivery by exploiting it for loading and triggering the release of a photosensitizer Chlorin e6 (Ce6) for simultaneous photodynamic (PDT) and photothermal therapy (PTT) in vitro. Here, we extended our previous in vitro studies to evaluate its effectiveness in vivo. Specifically, we pre-formed the protein corona from mouse serum (MS) around gold nanorods (NRs) and loaded it with Ce6 to form NR-MS-Ce6. The intravenous delivery of NR-MS-Ce6 at a dose of 10 mg kg-1 Au loaded with 9.63 μg kg-1 Ce6 into tumor-bearing NCr nude mice resulted in their tumor accumulation reaching a peak concentration of 560.3 μg Au per kg tissue (0.0752% dose) within 6 h post-injection. Subsequent localized laser irradiation of the xenograft tumor resulted in a significant tumor temperature increase of 16.85 °C within 20 min. Combined with the simultaneous reactive oxygen species (ROS) production by Ce6 for PDT, complete tumor regression was achieved within 19 days with no tumor regrowth up to 31 days. Similar to other NPs, significant gold accumulation was observed in the major reticuloendothelial system (RES) organs, particularly the liver and spleen, although no acute toxicity was observed histologically 31 days post-treatment. Our results demonstrated for the first time an in vivo application of the protein corona around NPs in the loading and delivery of drugs in small animals. The ease of drug loading and the biocompatibility of the endogenous serum-based protein corona could make it useful for drug delivery and therapeutic applications instead of merely being considered as a biological artefact to be eliminated.

Abstract
Owing to their unique properties, nanomaterials have been widely used in biomedicine since they have obvious inherent advantages over traditional ones. However, nanomaterials may also cause dysfunction in proteins, genes and cells, resulting in cytotoxic and genotoxic responses. Recently, more and more attention has been paid to these potential toxicities of nanomaterials, especially to the risks of nanomaterials to human health and safety. Therefore, when using nanomaterials for biomedical applications, it is of great importance to keep the balance between therapeutic efficiency and cytotoxicity (i.e., increase the therapeutic efficiency as well as decrease the potential toxicity). This requires a deeper understanding of the interactions between various types of nanomaterials and biological systems at the nano/bio interface. In this review, from the point of view of theoretical researchers, we will present the current status regarding the physical mechanism of cytotoxicity caused by nanomaterials, mainly based on recent simulation results. In addition, the strategies for minimizing the nanotoxicity naturally and artificially will also be discussed in detail. Furthermore, we should notice that toxicity is not always bad for clinical use since causing the death of specific cells is the main way of treating disease. Enhancing the targeting ability of nanomaterials to diseased cells and minimizing their side effects on normal cells will always be hugely challenging issues in nanomedicine. By combining the latest computational studies with some experimental verifications, we will provide special insights into recent advances regarding these problems, especially for the design of novel environment-responsive nanomaterials.

Abstract
Over the past few decades, nanoengineered particles have gained increasing interest for applications in the biomedical realm, including diagnosis, imaging, and therapy. When functionalized with targeting ligands, these particles have the potential to interact with specific cells and tissues, and accumulate at desired target sites, reducing side effects and improve overall efficacy in applications such as vaccination and drug delivery. However, when targeted particles enter a complex biological environment, the adsorption of biomolecules and the formation of a surface coating (e.g., a protein corona) changes the properties of the carriers and can render their behavior unpredictable. For this reason, it is of importance to consider the potential challenges imposed by the biological environment at the early stages of particle design. This review describes parameters that affect the targeting ability of particulate drug carriers, with an emphasis on the effect of the protein corona. We highlight strategies for exploiting the protein corona to improve the targeting ability of particles. Finally, we provide suggestions for complementing current in vitro assays used for the evaluation of targeting and carrier efficacy with new and emerging techniques (e.g., 3D models and flow-based technologies) to advance fundamental understanding in bio-nano science and to accelerate the development of targeted particles for biomedical applications.

Abstract
Following exposure to biological milieus (e.g. after systemic administration), nanoparticles (NPs) get covered by an outer biomolecular corona (BC) that defines many of their biological outcomes, such as the elicited immune response, biodistribution, and targeting abilities. In spite of this, the role of BC in regulating the cellular uptake and the subcellular trafficking properties of NPs has remained elusive. Here, we tackle this issue by employing multicomponent (MC) lipid NPs, human plasma (HP) and HeLa cells as models for nanoformulations, biological fluids, and target cells, respectively. By conducting confocal fluorescence microscopy experiments and image correlation analyses, we quantitatively demonstrate that the BC promotes a neat switch of the cell entry mechanism and subsequent intracellular trafficking, from macropinocytosis to clathrin-dependent endocytosis. Nano-liquid chromatography tandem mass spectrometry identifies apolipoproteins as the most abundant components of the BC tested here. Interestingly, this class of proteins target the LDL receptors, which are overexpressed in clathrin-enriched membrane domains. Our results highlight the crucial role of BC as an intrinsic trigger of specific NP-cell interactions and biological responses and set the basis for a rational exploitation of the BC for targeted delivery.

Abstract
The interface of bio-nano science and cancer medicine is an area experiencing much progress but also beset with controversy. Core concepts of the field-e.g., the enhanced permeability and retention (EPR) effect, tumor targeting and accumulation, and even the purpose of "nano" in cancer medicine-are hotly debated. In parallel, considerable advances in neighboring fields are occurring rapidly, including the recent progress of "immuno-oncology" and the fundamental impact it is having on our understanding and the clinical treatment of the group of diseases collectively known as cancer. Herein, we (i) revisit how cancer is commonly treated in the clinic and how this relates to nanomedicine; (ii) examine the ongoing debate on the relevance of the EPR effect and tumor targeting; (iii) highlight ways to improve the next-generation of nanomedicines; and (iv) discuss the emerging concept of working with (and not against) biology. While discussing these controversies, challenges, emerging concepts, and opportunities, we explore new directions for the field of cancer nanomedicine.

Abstract
Ball-milling utilizes mechanical stress to modify properties of carbon nanotubes (CNTs) including size, capping, and functionalization. Ball-milling, however, may introduce structural defects resulting in altered CNT-biomolecule interactions. Nanomaterial-biomolecule interactions result in the formation of the biocorona (BC), which alters nanomaterial properties, function, and biological responses. The formation of the BC is governed by the nanomaterial physicochemical properties and the physiological environment. Underlying disease states such as cardiovascular disease can alter the biological milieu possibly leading to unique BC identities. In this ex vivo study, we evaluated variations in the formation of the BC on single-walled CNTs (SWCNTs) due to physicochemical alterations in structure resulting from ball-milling and variations in the environment due to the high-cholesterol disease state. Increased ball-milling time of SWCNTs resulted in enhanced structural defects. Following incubation in normal mouse serum, label-free quantitative proteomics identified differences in the biomolecular content of the BC due to the ball-milling process. Further, incubation in cholesterol-rich mouse serum resulted in the formation of unique BCs compared to SWCNTs incubated in normal serum. Our study demonstrates that the BC is modified due to physicochemical modifications such as defects induced by ball-milling and physiological disease conditions, which may result in variable biological responses.

Abstract
Nanoparticles have great potential as drug delivery vehicles or as imaging agents for treatment and diagnosis of various diseases. It is therefore crucial to understand how nanoparticles are taken up by cells, both phagocytic and non-phagocytic. Small interference RNA has previously been used to isolate the effect of particular receptors in nanoparticle uptake by silencing their expression. Here we show that, when it comes to receptors with overlapping function, interpretation of such data has to be done with caution. We followed the uptake of silica nanoparticles by scavenger receptors in A549 lung epithelial cells. While we successfully knocked-down gene expression of several different receptors within the scavenger receptor family (SR-A1, MARCO, SR-BI, LOX-1 and LDLR) this caused reciprocal up and down regulation of the other scavenger receptors. Subsequent nanoparticle uptake experiments in silenced cells exhibit a complex behaviour, which could easily be misinterpreted if reciprocal regulation is not considered. Preliminary identification of the actual scavenger receptors involved can be found by disentangling the effects mathematically. Finally, we show that the effects are still present under more realistic biological conditions, namely at higher serum concentrations.

Abstract
While titanium is the metal of choice for most prosthetics and inner body devices due to its superior biocompatibility, the discovery of Ti-containing species in the adjacent tissue as a result of wear and corrosion has been associated with autoimmune diseases and premature implant failures. Here, we utilize the in situ liquid cell transmission electron microscopy (TEM) in a liquid flow holder and graphene liquid cells (GLCs) to investigate, for the first time, the in situ nano-bio interactions between titanium dioxide nanoparticles and biological medium. This imaging and spectroscopy methodology showed the process of formation of an ionic and proteic bio-camouflage surrounding Ti dioxide (anatase) nanoparticles that facilitates their internalization by bone cells. The in situ understanding of the mechanisms of the formation of the bio-camouflage of anatase nanoparticles may contribute to the definition of strategies aimed at the manipulation of these NPs for bone regenerative purposes.

Abstract
At present, bioferrofluids are employed as powerful multifunctional tools for biomedical applications such as drug delivery, among others. The present study explores the cellular response evoked when bile-acid platinum derivatives are conjugated with bioferrofluids by testing the biological activity in osteosarcoma (MG-63) and T-cell leukemia (Jurkat) cells. The aim of this work is to evaluate the biocompatibility of a bile-acid platinum derivative conjugated with multi-functional polymer coated bioferrofluids by observing the effects on the protein expression profiles and in intracellular pathways of nanoparticle-stimulated cells. To this end, a mass spectrometry-based approach termed SILAC has been applied to determine in a high-throughput manner the key proteins involved in the cellular response process (including specific quantitatively identified proteins related to the vesicular transport, cellular structure, cell cycle, biosynthetic process, apoptosis and regulation of the cell cycle). Finally, biocompatibility was evaluated and validated by conventional strategies also (such as flow cytometry, MTT, etc.).

Abstract
The range of possible nanostructures is so large and continuously growing, that collating and unifying the knowledge connected to them, including their biological activity, is a major challenge. Here we discuss a concept that is based on the connection of microscopic features of the nanomaterials to their biological impacts. We also consider what would be necessary to identify the features that control their biological interactions, and make them resemble each other in a biological context.

Abstract
The use of nanocarriers in biology and medicine is complicated by the current need to understand how nanoparticles interact in complex biological surroundings. When nanocarriers come into contact with serum, proteins immediately adsorb onto their surface, forming a protein corona which defines their biological identity. Although the composition of the protein corona has been widely determined by proteomics, its morphology still remains unclear. In this study we show for the first time the morphology of the protein corona using transmission electron microscopy. We are able to demonstrate that the protein corona is not, as commonly supposed, a dense, layered shell coating the nanoparticle, but an undefined, loose network of proteins. Additionally, we are now able to visualize and discriminate between the soft and hard corona using centrifugation-based separation techniques together with proteomic characterization. The protein composition of the ∼15 nm hard corona strongly depends on the surface chemistry of the respective nanomaterial, thus further affecting cellular uptake and intracellular trafficking. Large diameter protein corona resulting from pre-incubation with soft corona or Apo-A1 inhibits cellular uptake, confirming the stealth-effect mechanism. In summary, the knowledge on protein corona formation, composition and morphology is essential to design therapeutic effective nanoparticle systems.

Abstract
Research on nanoparticles has evolved into a major topic in chemistry. Concerning biomedical research, nanoparticles have decisively entered the field, creating the area of nanomedicine where nanoparticles are used for drug delivery, imaging, and tumor targeting. Besides these functions, scientists have addressed the specific ways in which nanoparticles interact with biomolecules, with proteins being the most prominent example. Depending on their size, shape, charge, and surface functionality, specifically designed nanoparticles can interact with proteins in a defined way. Proteins have typical dimensions of 5-20 nm. Ultrasmall nanoparticles (size about 1-2 nm) can address specific epitopes on the surface of a protein, for example, an active center of an enzyme. Medium-sized nanoparticles (size about 5 nm) can interact with proteins on a 1:1 basis. Large nanoparticles (above 20 nm) are big in comparison to many proteins and therefore are at the borderline to a two-dimensional surface onto which a protein will adsorb. This can still lead to irreversible structural changes in a protein and a subsequent loss of function. However, as most cells readily take up nanoparticles of almost any size, it is easily possible to use nanoparticles as transporters for proteins into a cell, for example, to address an internal receptor. Much work has been dedicated to this approach, but it is constrained by two processes that can only be observed in living cells or organisms. First, nanoparticles are usually taken up by endocytosis and are delivered into an intracellular endosome. After fusion with a lysosome, a degradation or denaturation of the protein cargo by the acidic environment or by proteases may occur before it can enter the cytoplasm. Second, nanoparticles are rapidly coated with proteins upon contact with biological media like blood. This so-called protein corona influences the contact with other proteins, cells, or tissue and may prevent the desired interaction. Essentially, these effects cannot be understood in purely chemical approaches but require biological environments and systems because the underlying processes are simply too complicated to be modeled in nonbiological systems. The area of nanoparticle-protein interactions strongly relies on different approaches: Synthetic chemistry is involved to prepare, stabilize, and functionalize nanoparticles. High-end analytical chemistry is required to understand the nature of a nanoparticle surface and the steps of its interaction with proteins. Concepts from supramolecular chemistry help to understand the complex noncovalent interactions between the surfaces of proteins and nanoparticles. Protein chemistry and biophysical chemistry are required to understand the behavior of a protein in contact with a nanoparticle. Finally, all chemical concepts must live up to the "biological reality", first in cell culture experiments in vitro and finally in animal or human experiments in vivo, to open new therapies in the 21st century. This interdisciplinary approach makes the field highly exciting but also highly demanding for chemists who, however, have to learn to understand the language of other areas.

Abstract
A single nanodevice based on gold nanorods (NRs) coloaded with a photosensitizer, Chlorin e6 (Ce6), and a chemotherapeutic, Doxorubicin (Dox), on its endogenously formed human serum (HS) protein corona, i.e., NR-HS-Ce6-Dox was developed with the aim of performing multimodal cancer therapy: photodynamic (PDT), photothermal (PTT) and chemotherapy (CTX) simultaneously upon irradiation with a single 665 nm laser. Here, the excitation of NRs and Ce6 resulted in photothermal ablation (PTT), and production of reactive oxygen species (ROS) to kill Cal 27 oral squamous cell carcinoma (OSCC) cells by oxidative stress (PDT) respectively, while the laser-triggered release of Dox intercalated into the DNA of cancer cells to result in DNA damage and cell death (CTX). High laser-triggered Dox release efficiency of 71.5% and strong plasmonic enhancement of ROS production by Ce6 (4.8-fold increase compared to free Ce6) was observed. Uptake of both Ce6 and Dox by Cal 27 cells was greatly enhanced, with 3.3 and 52 times higher intracellular Dox and Ce6 fluorescence observed, respectively, 6 h after dosing with NR-HS-Ce6-Dox compared to free drugs. The simultaneous trimodal therapy achieved a near complete eradication of cancer cells (98.7% cell death) with an extremely low dose of 15 pM NR-HS-Ce6-Dox loaded with just 1.26 nM Ce6 and 12.5 nM Dox due to strong synergistic enhancement in cancer cell kill compared to individual therapies performed separately. No dark toxicities were observed. These drug concentrations were far lower than any previously reported in vitro, thus eliminating any potential systemic toxicity of these agents.

Abstract
In order to direct nanocarriers to their targets efficiently, we have to understand the interactions occurring at the nano-bio interface between nanocarriers and human proteins, which forms the layer called the corona. However, experiments aiming to identify and quantify the proteins in the corona, especially critical steps in the separation of nanoparticles from biological media may affect the corona composition. Here, we used nano-LC MS/MS to compare the protein corona contents obtained after using two different separation methods. We showed that applying centrifugation versus magnetization to isolate nanoparticles surrounded by a corona resulted in protein loss and a reshuffling of their respective abundances.

Abstract
Nanoparticles (NPs) in contact with biological fluids experience changes in surface chemistry that can impact their biodistribution and downstream physiological impact. One such change involves the formation of a protein corona (PC) on the surface of NPs. Here we present a foundational study on PC formation following the incubation of polyvinylpyrrolidone-coated AgNPs (PVP-AgNPs, 50 nm) in the plasma of smallmouth bass (Micropterus dolomieu). PC formation increases with exposure time and is also affected by gender, with AgNPs incubated in male plasma having slightly thinner PCs and less negative zeta potentials than those incubated in female plasma. Proteomic analysis also revealed gender-specific differences in PC composition: in particular, egg-specific proteins (vitellogenin (VTG) and zona pellucida (ZP) were identified only in PCs derived from female plasma, raising the possibility of their roles in AgNP-related reproductive toxicity by promoting their accumulation in developing oocytes.

Abstract
In this Perspective, we describe current challenges and recent advances in efficient delivery and targeting of nanoparticles in vivo. We discuss cancer therapy, nanoparticle-biomolecule interactions, nanoparticle trafficking in cells, and triggers and responses to nanoparticle-cell interactions. No matter which functionalization strategy to target cancer is chosen, passive or active targeting, more than 99% of the nanoparticles administered in vivo end up in the mononuclear phagocytic system, mainly sequestered by macrophages. Comprehensive studies, such as the one reported by MacParland et al. in this issue of ACS Nano, will help to close the gap between nanotechnology-based drug-delivery solutions and advanced medicinal products.
