Cell-based in vitro blood-brain barrier model can rapidly evaluate nanoparticles' brain permeability in association with particle size and surface modification. Int J Mol Sci 2014; 15:1812-25.

Abstract
The possibility of nanoparticle (NP) uptake to the human central nervous system is a major concern. Recent reports showed that in animal models, nanoparticles (NPs) passed through the blood–brain barrier (BBB). For the safe use of NPs, it is imperative to evaluate the permeability of NPs through the BBB. Here we used a commercially available in vitro BBB model to evaluate the permeability of NPs for a rapid, easy and reproducible assay. The model is reconstructed by culturing both primary rat brain endothelial cells and pericytes to support the tight junctions of endothelial cells. We used the permeability coefficient (Papp) to determine the permeability of NPs. The size dependency results, using fluorescent silica NPs (30, 100, and 400 nm), revealed that the Papp for the 30 nm NPs was higher than those of the larger silica. The surface charge dependency results using Qdots® (amino-, carboxyl-, and PEGylated-Qdots), showed that more amino-Qdots passed through the model than the other Qdots. Usage of serum-containing buffer in the model resulted in an overall reduction of permeability. In conclusion, although additional developments are desired to elucidate the NPs transportation, we showed that the BBB model could be useful as a tool to test the permeability of nanoparticles.

Abstract
Silicon quantum dots (Si-QDs) have great potential for biomedical applications, including their use as biological fluorescent markers and carriers for drug delivery systems. Biologically inert Si-QDs are less toxic than conventional cadmium-based QDs, and can modify the surface of the Si-QD with covalent bond. We synthesized water-soluble alminoprofen-conjugated Si-QDs (Ap-Si). Alminoprofen is a non-steroid anti-inflammatory drug (NSAID) used as an analgesic for rheumatism. Our results showed that the "silicon drug" is less toxic than the control Si-QD and the original drug. These phenomena indicate that the condensed surface integration of ligand/receptor-type drugs might reduce the adverse interaction between the cells and drug molecules. In addition, the medicinal effect of the Si-QDs (i.e., the inhibition of COX-2 enzyme) was maintained compared to that of the original drug. The same drug effect is related to the integration ratio of original drugs, which might control the binding interaction between COX-2 and the silicon drug. We conclude that drug conjugation with biocompatible Si-QDs is a potential method for functional pharmaceutical drug development.

Abstract
Quantum Dots (QDs) are a new class of semiconductor nanoparticulate luminophores, which are actively researched for novel applications in biology and nanomedicine. In this review, the recent progress in the design and applications of QD labels for in vitro and in vivo imaging of cells is presented. Surface chemical engineering of hydrophobic QDs is required to render them water soluble and biocompatible. Further surface modification and attachment of bioactive molecules to the surface of QDs, such as peptides, aptamers, or antibodies are intensively explored for targeted imaging of living cells, and disease states in animals. Specially designed surface coatings can drastically decrease nonspecific interactions between QDs and cells, minimize degradation of QDs under in vivo physiological conditions, reduce the cytotoxicity of QDs, and prolong circulation lifetimes in animals. New generations of QD probes are also promising for imaging cellular processes at the single-molecule level. Ultimately, QDs as components of complex therapeutic nanosystems are poised to contribute significantly to the field of personalized medicine.

Abstract
To develop novel gene delivery carriers, aminated polysorbate 80 (P80-NH(2)) was synthesized with strong positively charged properties through the introduction of three amine groups. The resulting P80-NH(2) and DNA polyplex exhibited superb condensation abilities due to the high densities of positively charged amines groups. Size and surface charge of polyplex were shown to be well suited for cellular internalization. In addition, the P80-NH(2) /DNA polyplex demonstrated acceptable transfection efficiency in HeLa cells and was nontoxic relative to the conventional 25-kDa polyethyleneimine system.

Abstract
With the development of nanotechnology, nanometer-sized products smaller than several 100 nm have been applied for all areas of science and technology. The nanometer-sized products, including carbon nanotubes, fullerene derivatives, and nanocrystals made of various materials, are widely employed as novel tools in various fields, not only in material engineering, electronics, plastics, automobile, aviation, and aerospace industries, but also even in cellular biology, molecular biology, and basic and clinical medical fields. In particular, nanocrystal quantum dots (QDs) have been widely used in biological and medical studies because of their far brighter photoemission and photostability. The physical and chemical properties of QDs have been circumstantially investigated, but little is known about the potential harmful effects of QDs on human health. In addition to the physical and chemical properties of the QDs, their toxicity and biological behavior are generally regulated by three other conditions: (1) the QD core material itself, (2) the surface modifications of the QD, and (3) the external environmental condition of the QDs. We herein report on the in vitro and in vivo toxicity and biological behavior of nanocrystals such as QDs. Accumulating evidence suggests that the QD-capping material, rather than the core metalloid complex, is responsible for the majority of their toxicity and biological activity. For example, molecules covered with a toxic agent showed cytotoxicity, whereas QDs conjugated with biomolecules retained the biological effects of the conjugate.

Abstract
Semiconductor quantum dots (QDs) coated with thioalkyl acid ligands are often used as probes and reporters for nucleic acid sensing, or protein sensing using aptamers, and are also potential vectors for gene delivery. In such applications, the interactions that potentially lead to the adsorption of oligonucleotides onto the surface of colloidal QDs are an important consideration. To explore such interactions, fluorescence resonance energy transfer (FRET) between QDs and oligonucleotides labeled with a fluorescent dye was used to identify and characterize a set of conditions that favor strong adsorption on 3-mercaptopropionic acid (MPA)-coated CdSe/ZnS QDs. Adsorption curves and competitive binding experiments were used to determine that the order of affinity for nucleobase adsorption was dC>dA≥dG≫dT. The length of the oligonucleotide sequence was also important, with an 80-mer sequence adsorbing more strongly than its 20-mer analog. Adsorption decreased with increasing pH and corresponded to the ionization of the carboxylic acid groups of the MPA ligands. Increased ionic strength partially offsets ligand ionization and increased the extent of adsorption. The interaction between QDs and oligonucleotides was labile, with increases in adsorption at lower concentrations of oligonucleotide and with an increasing number of oligonucleotides per QD. The results were consistent with a hydrogen-bonding model for adsorption, where neutral thioalkyl acid ligands interact favorably with nucleobases and ionized ligands resist adsorption.

Abstract
Bioconjugated nanomaterials offer endless opportunities to advance both nanobiotechnology and biomedical technology. In this regard, semiconductor nanoparticles, also called quantum dots, are of particular interest for multimodal, multifunctional and multiplexed imaging of biomolecules, cells, tissues and animals. The unique optical properties, such as size-dependent tunable absorption and emission in the visible and NIR regions, narrow emission and broad absorption bands, high photoluminescence quantum yields, large one- and multi-photon absorption cross-sections, and exceptional photostability are the advantages of quantum dots. Multimodal imaging probes are developed by interfacing the unique optical properties of quantum dots with magnetic or radioactive materials. Besides, crystalline structure of quantum dots adds scope for high-contrast X-ray and TEM imaging. Yet another unique feature of a quantum dot is its spacious and flexible surface which is promising to integrate multiple ligands and antibodies and construct multi-functional probes for bioimaging. In this critical review, we will summarize recent advancements in the preparation of biocompatible quantum dots, bioconjugation of quantum dots, and applications of quantum dots and their bioconjugates for targeted and nonspecific imaging of extracellular and intracellular proteins, organelles and functions (181 references).

Abstract
Fluorescent nanocrystal quantum dots (QDs) are widely used as novel tools in various biological fields including cellular biology, molecular biology, and even in basic and clinical medical fields, due to their far brighter photoemission and photostability. Although many amounts of biological studies, including in vivo experiments, were circumstantially investigated, there is no informative report that investigates whether the QDs affect the mammalian immune system. This study investigated the immune response and biological behavior of QDs in vitro and in vivo. The immune response to QDs by both lymphocytes and kinds of macrophages in vitro and in vivo was investigated. Co-culture of QDs with immune cells showed that apparently normal production of cytokines and chemokines in both mouse CD4+ lymphocytes and peritoneal F4/80+ macrophages (PM phi). In addition, the bionanocomplex of QDs with enhanced-green-fluorescent-protein (eGFP)-encoding nucleotides successfully induced the expression of eGFP protein by PM phi. However, direct injection of QD+nucleotides bionanocomplex aqueous solution into the peritoneal cavity of mice resulted in the inflammation with the infiltration of inflammatory cells into the peritoneal cavity. Furthermore, QD+nucleotides bionanocomplex (but not QD bionanocomplex without nucleotides), induced the production of both proinflammatory cytokines and chemokines by PM phi in vitro. These results indicated that QDs covered with nucleotides caused the peritoneal inflammation in vivo via activation of PM phi and probably nonimmune cells. Taken together, these data indicated that QDs affect the proliferation of immune cells, but not in immune response including cytokine production. We propose here that all nanotechnology researchers should confirm the biological responses of their nanoscale products, because the biological response against nanoscale products can be occurred by not only in immune cells but also other nonimmune cells.
