Abstract
Quinine is a promising natural product building block for polymer-based nucleic acid delivery vehicles as its structure enables DNA binding through both intercalation and electrostatic interactions. However, studies exploring the potential of quinine-based polymers for nucleic acid delivery applications (transfection) are limited. In this work, we used a hydroquinine-functionalized monomer, HQ, with 2-hydroxyethyl acrylate to create a family of seven polymers (HQ-X, X = mole percentage of HQ), with mole percentages of HQ ranging from 12 to 100%. We developed a flow cytometer-based assay for studying the polymer-pDNA complexes (polyplex particles) directly and demonstrate that polymer composition and monomer structure influence polyplex characteristics such as the pDNA loading and the extent of adsorption of serum proteins on polyplex particles. Biological delivery experiments revealed that maximum transgene expression, outperforming commercial controls, was achieved with HQ-25 and HQ-35 as these two variants sustained gene expression over 96 h. HQ-44, HQ-60, and HQ-100 were not successful in inducing transgene expression, despite being able to deliver pDNA into the cells, highlighting that the release of pDNA is likely the bottleneck in transfection for polymers with higher HQ content. Using confocal imaging, we quantified the extent of colocalization between pDNA and lysosomes, proving the remarkable endosomal escape capabilities of the HQ-X polymers. Overall, this study demonstrates the advantages of HQ-X polymers as well as provides guiding principles for improving the monomer structure and polymer composition, supporting the development of the next generation of polymer-based nucleic acid delivery vehicles harnessing the power of natural products.

Abstract
Nuclear targeted delivery has great potential in improving the efficiency of non-viral carrier mediated genome editing. However, direct and efficient delivery of CRISPR/Cas9 plasmid into the nucleus remains a challenge. In this study, a nuclear targeted gene delivery platform based on fluorescent carbon quantum dots (CQDs) was developed. Polyethylenimine (PEI) and polyethylene glycol (PEG) synergistically passivated the surface of CQDs, providing an excitation-independent green-emitting fluorescent CQDs-PEI-PEG conjugate (CQDs-PP) with an ultra-small size and positive surface charge. Here we show that CQDs-PP could bind CRISPR/Cas9 plasmid to form a nano-complex by electrostatic attraction, which can bypass lysosomes and enter the nucleus by passive diffusion, and thereby improve the transfection efficiency. Also, CQDs-PP could deliver CRISPR/Cas9 plasmid into HeLa cells, resulting in the insertion/deletion mutation of the target EFHD1 gene. More importantly, CQDs-PP exhibited a considerably higher gene editing efficiency as well as comparable or lower cytotoxicity relative to Lipo2000 and PEI-passivated CQDs-PEI (CQDs-P). Thus, the nuclear-targeted CQDs-PP is expected to constitute an efficient CRISPR/Cas9 delivery carrier in vitro with imaging-trackable ability.

Abstract
Creating a well-defined nanostructure through de-oxyribo nucleic acid (DNA)-nanotechnology, and specifically the development of metal/inorganic semiconductor junctions on DNA-assembled nanostructures, is an emerging research area. Herein, we investigate the electrical properties of biomolecule DNA-template based one-dimensional nanowires (NWs)-CdS/Au and without-template based nanoparticles (NPs)-CdS/Au devices grown on the Indium Tin Oxide (ITO) glass substrates. More importantly, the NWs-CdS/Au device displays a dramatic augmentation of current flow and also a striking change in threshold voltage (~55 mV) in comparison to NPs (~190 mV) and reported bulk-CdS/Au (~680 mV) devices. Albeit the manifestation of non-linear/asymmetric current-voltage (I-V) characteristic establishes the CdS/Au junction as Schottky device, but captivatingly, the large ideality factor of about 24 found in NWs-CdS/Au device could be due to the DNA-assembled based organic process CdS-semiconductor. Capacitance-voltage (C-V) measurements of the NWs-CdS/Au divulge a remarkable hump-like feature at lower frequency owing to the frequency dispersion effect. In contrast, the effect appears to be enfeebled with increasing frequency. We conjecture that the density of surface/interface traps materialises at the interface of nanostructures-CdS/metal-Au results in the changes in underlying electrical properties. The observation of significant differences in the electrical properties of DNA-assembled NWs-based Schottky junctions could possibly be helpful for the fabrication of more sophisticated and higher multispecificity biosensors for medical applications.

Abstract
Polymeric vehicles that efficiently package and controllably release nucleic acids enable the development of safer and more efficacious strategies in genetic and polynucleotide therapies. Developing delivery platforms that endogenously monitor the molecular interactions, which facilitate binding and release of nucleic acids in cells, would aid in the rational design of more effective vectors for clinical applications. Here, we report the facile synthesis of a copolymer containing quinine and 2-hydroxyethyl acrylate that effectively compacts plasmid DNA (pDNA) through electrostatic binding and intercalation. This polymer system poly(quinine-co-HEA) packages pDNA and shows exceptional cellular internalization, transgene expression, and low cytotoxicity compared to commercial controls for several human cell lines, including HeLa, HEK 293T, K562, and keratinocytes (N/TERTs). Using quinine as an endogenous reporter for pDNA intercalation, Raman imaging revealed that proteins inside cells facilitate the unpackaging of polymer-DNA complexes (polyplexes) and the release of their cargo. Our work showcases the ability of this quinine copolymer reporter to not only facilitate effective gene delivery but also enable diagnostic monitoring of polymer-pDNA binding interactions on the molecular scale via Raman imaging. The use of Raman chemical imaging in the field of gene delivery yields unprecedented insight into the unpackaging behavior of polyplexes in cells and provides a methodology to assess and design more efficient delivery vehicles for gene-based therapies.

Abstract
Non-viral gene delivery systems have great potential for safe and efficient gene therapy, while inefficient cellular and nuclear uptake remain as the major hurdles. Novel approaches are needed to enhance the transfection efficiency of non-viral vectors. In accordance with this need, the objective of this study was to construct a non-viral vector that could achieve gene delivery without using additional lipid-based transfection agent. We aimed to impart self-delivery property to a non-viral vector by using the cell and nucleus penetrating properties of YopM proteins from the three Yersinia spp. (Y. pestis, Y. enterocolotica and Y. pseudotuberculosis). Plasmid DNA (pDNA) encoding green fluorescent protein (GFP) was labeled with quantum dots (QDs) via peptide-nucleic acid (PNA) recognition site. Recombinant YopM protein was then attached to the conjugate via a second PNA recognition site. The YopM ̶ QDs ̶ pDNA conjugate was transfected into HeLa cells without using additional transfection reagent. All three conjugates produced GFP fluorescence, indicating that the plasmid was successfully delivered to the nucleus. As control, naked pDNA was transfected into the cells by using a commercial transfection reagent. The Y. pseudotuberculosis YopM-functionalized conjugate achieved the highest GFP expression, compared to other two YopM proteins and the transfection reagent. To the best of our knowledge, YopM protein was used for the first time in a non-viral gene delivery vector.

Abstract
As the focus has shifted from traditional killed or live, attenuated vaccines toward subunit vaccines, improvements in vaccine safety have been confronted with low immunogenicity of protein antigens. This issue has been addressed by synthesizing and designing a wide variety of antigen carriers and adjuvants, such as Toll-like receptor agonists (e.g., MPLA, CpG). Studies have focused on optimizing adjuvants for improved cellular trafficking, cytosolic availability, and improved antigen presentation. In this work, we describe the design of novel amphiphilic pentablock copolymer (PBC) adjuvants that exhibit high biocompatibility and reversible pH- and temperature-sensitive micelle formation. We demonstrate improved humoral immunity in mice in response to single-dose immunization with PBC micelle adjuvants compared with soluble antigen alone. With the motive of exploring the mechanism of action of these PBC micelles, we studied intracellular trafficking of these PBC micelles with a model antigen and demonstrated that the PBC micelles associate with the antigen and enhance its cytosolic delivery to antigen-presenting cells. We posit that these PBC micelles operate via immune-enhancing mechanisms that are different from that of traditional Toll-like receptor activating adjuvants. The metabolic profile of antigen-presenting cells stimulated with traditional adjuvants and the PBC micelles also suggests distinct mechanisms of action. A key finding from this study is the low production of nitric oxide and reactive oxygen species by antigen-presenting cells when stimulated by PBC micelle adjuvants in sharp contrast to TLR adjuvants. Together, these studies provide a basis for rationally developing novel vaccine adjuvants that are safe, that induce low inflammation, and that can efficiently deliver antigen to the cytosol.

Abstract
This paper reports dual enhanced electrochemiluminescence (ECL) of CdS quantum dot (QD)-decorated aminated Au@SiO2 core/shell (Au@SiO2-NH2/CdS) superstructures. A maximum ECL emission of the Au@SiO2-NH2/CdS superstructures (Au core, ca. 55 nm) with a silica shell of 38 nm was 35-fold stronger than that of the counterparts (containing neither Au cores nor amino groups) with H2O2 as a coreactant. The fold of ECL enhancement is the largest, and the optical path of maximum ECL enhancement is the longest reported so far. The larger the Au cores in the superstructures, the stronger the ECL emission of CdS QDs was. Two types of ECL enhancement mechanisms were clearly proposed for the dual enhanced ECL of the Au@SiO2-NH2/CdS superstructures. One was the electromagnetic field enhancement induced by localized surface plasmon resonance of Au cores, and the other was the chemical enhancement from amino groups modified on the silica surface involved in the ECL process in the assistance of H2O2. It is the first time to put forward the new concept of chemical enhanced ECL that was directly related to the participation of other chemicals, which caused a decrease in the difference in the redox potential between emitters and coreactants for the increase of their redox currents. The constructed ECL platform was demonstrated to have promising applications in highly sensitive detection of glutathione (GSH), and the response mechanism of GSH was also explored.

Abstract
A new type of multifunctional quantum dot (QD)-polypeptide hybrid nanogel with targeted imaging and drug delivery properties has been developed by metal-affinity driven self-assembly between artificial polypeptides and CdSe-ZnS core-shell QDs. On the surface of QDs, a tunable sandwich-like microstructure consisting of two hydrophobic layers and one hydrophilic layer between them was verified by capillary electrophoresis, transmission electron microscopy, and dynamic light scattering measurements. Hydrophobic and hydrophilic drugs can be simultaneously loaded in a QD-polypeptide nanogel. In vitro drug release of drug-loaded QD-polypeptide nanogels varies strongly with temperature, pH, and competitors. A drug-loaded QD-polypeptide nanogel with an arginine-glycine-aspartic acid (RGD) motif exhibited efficient receptor-mediated endocytosis in αvβ3 overexpressing HeLa cells but not in the control MCF-7 cells as analyzed by confocal microscopy and flow cytometry. In contrast, non-targeted QD-polypeptide nanogels revealed minimal binding and uptake in HeLa cells. Compared with the original QDs, the QD-polypeptide nanogels showed lower in vitro cytotoxicity for both HeLa cells and NIH 3T3 cells. Furthermore, the cytotoxicity of the targeted QD-polypeptide nanogel was lower for normal NIH 3T3 cells than that for HeLa cancer cells. These results demonstrate that the integration of imaging and drug delivery functions in a single QD-polypeptide nanogel has the potential for application in cancer diagnosis, imaging, and therapy.

Abstract
Semiconductor quantum dots (QDs) or nanoparticles (NPs) exhibit very unusual physico-chemcial and optical properties. This review article introduces the applications of semiconductor nanomaterials (NMs) in fluorescence spectroscopy and matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for biomolecule analysis. Due to their unique physico-chemical and optical properties, semiconductors NMs have created many new platforms for investigating biomolecular structures and information in modern biology. These semiconductor NMs served as effective fluorescent probes for sensing proteins and cells and acted as affinity or concentrating probes for enriching peptides, proteins and bacteria proteins prior to MALDI-MS analysis.

Abstract
The control of the DNA condensation process is essential for compaction of DNA in chromatin, as well as for biological applications such as nonviral gene therapy. This review endeavours to reflect the progress of investigations on DNA condensation effects of nanostructure-based condensing agents (such as nanoparticles, nanotubes, cationic polymer and peptide agents) observed by using atomic force microscopy (AFM) and other techniques. The environmental effects on structural characteristics of nanostructure-induced DNA condensates are also discussed.

Abstract
Gene therapy is the modification of gene expression to treat a disease. However, efficient intracellular delivery and monitoring of gene therapeutic agents is an ongoing challenge. Use of theranostic agents with suitable targeted, controlled delivery and imaging modalities has the potential to greatly advance gene therapy. Inorganic nanoparticles including magnetic nanoparticles, gold nanoparticles, and quantum dots have been shown to be effective theranostic agents for the delivery and spatiotemporal tracking of oligonucleotides in vitro and even a few cases in vivo. Major concerns remain to be addressed including cytotoxicity, particularly of quantum dots; effective dosage of nanoparticles for optimal theranostic effect; development of real-time in vivo imaging; and further improvement of gene therapy efficacy.

Abstract
This paper proposes a novel methodology to improve noncollisional photochemical reactions such as Förster resonance energy transfer on solid surfaces. Since an excited guest molecule densely adsorbed on the solid surfaces is quenched by an unfavorable interaction between guests in general, the photochemical reactions such as electron and energy transfers tend to be inefficient compared to those in homogeneous systems. In this work, the mechanism of unfavorable quenching process of dyes on the clay surface as a typical solid surface for the photochemical energy transfer was systematically investigated by using a series of porphyrin derivatives. As a result, it was found that the quenching rate constants of excited guest dye determined by the time-resolved fluorescence measurements correlated well with the strengths of coulombic interaction between host and guest. The strong coulombic interaction should suppress the mobility and collision frequency of guests on the clay surface; thus, the collision of guest molecules was revealed as the origin of unfavorable quenching for photochemical reactions on the clay surface. According to this principle, we will be able to construct efficient photochemical reaction systems without any quenching process, such as efficient energy transfers toward an artificial light-harvesting system. In fact, we have already realized almost 100% energy transfer by the suppression of quenching process on the clay surface (e.g., J. Am. Chem. Soc.2011, 133, 14280-14286).

Abstract
Quantum dots (QDs) coated with an albumin-derived copolymer shell exhibit significant photoresponsiveness to DNA loading and have great potential for investigating gene delivery processes. The QDs reported herein are positively charged, have attractive optical properties, and are noncytotoxic and notably stable in live cells. Their complex formation with plasmid DNA leads to proportionally decreased photoluminescence and efficient gene transfection is observed. Therefore, they are suitable for live-cell bioimaging and mechanistic studies of nonviral gene delivery. Fluorescence correlation spectroscopy is applied for the first time to investigate individual QDs diffusing in large endosomes inside living cells, and serves as a valuable tool to study the physical properties of QDs inside live cells. The data obtained in this study strongly support the notable stability of these QDs, even in cell endosomes.

Abstract
Nonviral delivery of nucleic acids is a potentially safe and viable therapeutic modality for inherited and acquired diseases. However, current systems have proven too inefficient for widespread clinical translation. The rational design of improved carriers depends on a quantitative, mechanistic understanding of the rate-limiting barriers to efficient intracellular delivery. Separation of the nucleic acid from the carrier is one of the barriers, which may be analyzed by Förster resonance energy transfer (FRET), a mechanism used to detect interactions between fluorescently labeled molecules. When applied to the molecular components of polymer or lipid-based nanocomplexes, FRET provides information on their complexation status, uptake, release and degradation. Recently, the design of FRET systems incorporating quantum dots as energy donors has led to improved signal stability, allowing prolonged measurements, as well as increased sensitivity, enabling direct detection and the potential for multiplexing. The union of quantum dots and FRET is providing new insights into the mechanisms of nonviral nucleic acid delivery through convergent characterization of delivery barriers, and has the potential to accelerate the design of improved carriers to realize the potential of nucleic acid therapeutics and gene medicine.

Abstract
Protection of genes against enzymatic degradation and overcoming of cellular barriers are critical for efficient gene delivery. The effectiveness of gene delivery by nonviral vectors depends mostly on the extent of DNA packaging or condensation. We show that Förster resonance energy transfer (FRET)-mediated photodecomposition of undesired acceptors in doubly labeled plasmid DNA (pDNA) and FRET recovery after acceptor photodecomposition (FRET-RAP) are effective methods for the detection of DNA condensation and decondensation. Our hypothesis is that undesired acceptors within the Förster distance of highly-photostable donors in precondensed DNA can be selectively photodecomposed by FRET. We investigate this hypothesis by the random labeling of pcDNA3.1-GL3 and pUC18DNA with quantum dots (QDs) as the energy donor and AlexaFluor594 or Cy5 as the acceptor. At first, the random labeling generates efficient FRET, also called intrinsic FRET, in precondensed DNA, which prevents us from decoding any changes in the FRET efficiency during DNA condensation. Next, we suppressed the intrinsic FRET by the FRET-mediated photodecomposition of acceptors within the Förster distance of QDs. Conversely, many acceptors kept intact beyond the Förster distance provide us with high FRET efficiency during the condensation of pDNA using protamine. Further, the FRET efficiency is significantly decreased during the decondensation of DNA using heparan sulfate and glutathione. The random labeling of DNA using excess acceptors around photostable donors followed by the FRET-mediated photodecomposition of undesired acceptors can be a promising method for not only the sensitive detection of DNA condensation by FRET but also the customization of biomolecular sensors.

Abstract
The nucleocytoplasmic partitioning of nanoparticles as a result of cell division is highly relevant to the field of nonviral gene delivery. We reviewed the literature on the intracellular distribution of cell organelles (the endosomal vesicles, Golgi apparatus, endoplasmic reticulum and nucleus), foreign macromolecules (dextrans and plasmid DNA) and inorganic nanoparticles (gold, quantum dot and iron oxide) during mitosis. For nonviral gene delivery particles (lipid- or polymer-based), indirect proof of nuclear entry during mitosis is provided. We also describe how retroviruses and latent DNA viruses take advantage of mitosis to transfer their viral genome and segregate their episomes into the host daughter nuclei. Based on this knowledge, we propose strategies to improve nonviral gene delivery in dividing cells with the ultimate goal of designing nonviral gene delivery systems that are as efficient as their viral counterparts but non-immunogenic, non-oncogenic and easy and inexpensive to prepare.
