Abstract
Vaccines have become one of the most effective strategies to deal with various infectious diseases and chronic noninfectious diseases, such as SARS virus, Novel Coronavirus, cancer, etc. However, recent studies have found that the neutralizing antibody titers induced by vaccines would drop to half level or even lower after vaccination. In this study, we designed a novel small-sized positively charged nanofiber-1 (PEI-CNF-1) as a vaccine carrier, which can induce a high long-term humoral immune response by controlled release of antigen. Further studies showed that PEI-CNF-1 could significantly induce the release of immune response factor IL-1βand bone marrow-derived cell (BMDC) maturation. Moreover, compare to other cellulose nanofibers (CNFs), PEI-CNF-1 combined antigen (ovalbumin, OVA) induced and maintained the highest and longest antibody titers after vaccination. Interestingly, the antibody titers have no significant difference between at 21 and 90 d. Mechanically, we found that PEI-NCF-1 not only could control the slow-release of antigen, but also could be more easily swallowed by macrophages and metabolized by the bodies, thus presenting antigen more effectively. In conclusion, we believe that PEI-CNF-1 have a very high application prospect in inducing long-term humoral immune response, so as to achieve efficient prevention effect to epidemic viruses.

Abstract
HYPOTHESIS Iron oxide and other ferrite nanoparticles have not yet found widespread application in the medical field since the translation process faces several big hurdles. The incomplete knowledge of the interactions between nanoparticles and living organisms is an unfavorable factor. This complex subject should be made simpler by synthesizing magnetic nanoparticles with good physical (relaxivity) and chemical (colloidal stability, anti-fouling) properties and no biological activity (no immune-related effects, minimal internalization, fast clearance). Such an innocent scaffold is the main aim of the present paper. We systematically searched for it within the class of small-to-medium size ferrite nanoparticles coated by small (zwitter)ionic ligands. Once established, it can be functionalized to achieve targeting, drug delivery, etc. and the observed biological effects will be traced back to the functional molecules only, as the nanosized scaffold is innocent. EXPERIMENTS We synthesized nine types of magnetic nanoparticles by systematic variation of core composition, size, coating. We investigated their physico-chemical properties and interaction with serum proteins, phagocytic microglial cells, and a human model of inflammation and studied their biodistribution and clearance in healthy mice. The nanoparticles have good magnetic properties and their surface charge is determined by the preferential adsorption of anions. All nanoparticle types can be considered as immunologically safe, an indispensable pre-requisite for medical applications in humans. All but one type display low internalization by microglial BV2 cells, a process strongly affected by the nanoparticle size. Both small (3 nm) and medium size (11 nm) zwitterionic nanoparticles are in part captured by the mononuclear phagocyte system (liver and spleen) and in part rapidly (≈1 h) excreted through the urinary system of mice. FINDINGS The latter result questions the universality of the accepted size threshold for the renal clearance of nanoparticles (5.5 nm). We suggest that it depends on the nature of the circulating particles. Renal filterability of medium-size magnetic nanoparticles is appealing because they share with small nanoparticles the decreased accumulation-related toxicity while performing better as magnetic diagnostic/therapeutic agents thanks to their larger magnetic moment. In conclusion, many of our nanoparticle types are a bio-compatible innocent scaffold with unexpectedly favorable clearance.

Abstract
The existence of challenging diseases such as cancers, HIV and Zika requires developing new vaccines that can generate tunable and robust immune responses against the diseases. Biomaterials-based techniques have been broadly explored for designing vaccines that can produce controllable and potent immunity. Among the existing biomaterials-based strategies, the layer-by-layer (LbL) assembly technique is remarkably attractive in vaccine design due to its unique features such as programmed and versatile cargo loading, cargo protection, co-delivery, juxtaposing of immune signals, etc. In this work, we reviewed the existing LbL-based vaccine design techniques for translational applications. Specifically, we discussed nanovaccines constructed by coating polyelectrolyte multilayers (PEMs) on nanoparticles, microcapsule vaccines assembled from PEMs, polyplex/complex vaccines condensed from charged materials and microneedle vaccines deposited with PEMs, highlighting the employment of these techniques to promote immunity against diseases ranging from cancers to infectious and autoimmune diseases (i.e., HIV, influenza, multiple sclerosis, etc.). Additionally, the review specifically emphasized using LbL-based vaccine technologies for tuning the cellular and molecular pathways, demonstrating the unique advantages presented by these vaccination strategies. These studies showed the versatility and potency of using LbL-based techniques for designing the next generation of biomaterials vaccines for translational purposes.

Vaccine 2019; 37:1503-1515.

Abstract
We previously developed an highly efficacious combination adjuvant comprised of innate defense regulator (IDR)-1002 peptide, poly(I:C) and polyphosphazene (TriAdj). Here we aimed to design and test the in vivo efficacy of a mucoadhesive nasal formulation of this adjuvant. To determine the physical properties of the formulation, the effect of addition of each individual component was characterised by gel electrophoresis and fluorescence quenching using rhodamine-poly(I:C). Cationic liposomes comprised of didodecyl dimethylammonium bromide (DDAB), dioleoyl phosphatidylethanolamine (DOPE) (50:50 or 75:25 mol:mol) and DDAB, L-α-phosphatidylcholine (egg PC) and DOPE (40:50:10 mol:mol:mol) were prepared by the thin-film extrusion method. The liposomes and TriAdj were combined by simple mixing. The formed complex (L-TriAdj) was characterized by dynamic light scattering, zeta potential, and mucin interactions. We found that IDR-1002 peptide, polyphosphazene and poly(I:C) self-assembled in solution forming an anionic complex. Exposure of RAW267.4 mouse macrophage cells to TriAdj alone vs. L-TriAdj indicated that DDAB/DOPE (50:50) and DDAB/EPC/cholesterol (40:50:10) complexation reduced TriAdj toxicity. Next, TriAdj-containing cationic liposomes were prepared at several molar ratios to determine optimal size, stability and desired positive charge. Transmission electron microscopy showed rearrangement of lipid structures on binding of liposomes to TriAdj and to mucin. Stable particles (<200 nm over 24 h) showed mucin binding of DDAB/DOPE + TriAdj was greater than DDAB/EPC/DOPE + TriAdj. To verify in vivo efficacy, mice were administered the DDAB/DOPE + TriAdj complex intranasally with ovalbumin as the antigen, and the immunogenic response was measured by ELISA (serum IgG1, IgG2a, IgA) and ELISpot assays (splenocyte IL-5, IFN-γ). Mice administered adjuvant showed a significantly greater immune response with L-TriAdj than TriAdj alone, with a dose-response proportionate to the triple adjuvant content, and an overall balanced Th1/Th2 immune response representing both systemic and mucosal immunity.

Abstract
In this study, Mussel-inspired polydopamine (PDA) nanospheres were synthesized via spontaneous oxidative polymerization of dopamine hydrochloride (dopa-HCl) in a deionized water-alcohol mixed solvent at room temperature and atmospheric air, under alkaline condition. Field-emission scanning electron microscopy (FE-SEM) demonstrated production of sphere-like shape with a smooth surface and tunable size, while monodispersity increased by utilizing isopropanol instead of ethanol owing to lower Ra values based on Hansen solubility parameter (HSP) theory. Dropwise addition of monomer played an undeniable role in the fabrication of uniform and smaller spheres. The difference of the charge repulsion of constructs in the range of pH led to different dispersive behavior in a variety of solvents, exhibiting versatile applications. The presence of active functional groups on the surface of PDA spheres made them an appropriate option for PDA-assisted biomimetic mineralization of hydroxyapatite (HA), which is the result of the interaction between abundant catecholamine moieties in PDA and Ca+2 ions in simulated body fluid. Bio-adhesive nature of PDA in water and the presence of amino and hydroxyl functional groups support desirable L929 mouse fibroblast cell spreading. The viability of >90% fibroblast cells proved the biocompatibility of polymerized structure. All the achievements indicated that PDA nanospheres provide a biocompatible and bioactive template for green synthesizing hydroxyapatite and the innovative basis for further tissue engineering applications.

Abstract
Poly(ethylene glycol) (PEG), which is considered as a gold standard for surface modification of nanoparticles in biomedical applications, has been reported to encounter the accelerated blood clearance (ABC) phenomenon after repeated administration. Herein, as an ideal substitute for PEG, a zwitterionic peptide sequence of alternating negatively charged glutamic acid (E) and positively charged lysine (K) was designed as a good candidate for surface modification of nanoparticles without the ABC phenomenon in vivo. PEG-protected gold nanoparticles (AuNP-PEG) suffered from a serious ABC phenomenon with very fast blood clearance after repeated injection. Meanwhile, the plasma IgM and IgG levels were significantly increased after the repeated injection of AuNP-PEG. However, zwitterionic stealth peptide-protected gold nanoparticles (AuNP-EK10) could avoid the activation of the ABC phenomenon. The increase of IgM and IgG levels was not observed after the repeated injection of AuNP-EK10. More interestingly, compared to AuNP-PEG, more AuNP-EK10 could be accumulated in tumor tissues after repeated injection of the nanoparticles to tumor-bearing nude mice, which might be especially important for the design of drug nanocarriers in cancer therapy.

Abstract
Surgical resection is recognized as a mainstay in the therapy of malignant brain tumors. In clinical practice, however, surgeons face great challenges in identifying the tumor boundaries due to the infiltrating and heterogeneous nature of neoplastic tissues. Contrast-enhanced magnetic resonance imaging (MRI) is extensively used for defining the brain tumor in clinic. Disappointingly, the commercially available (MR) contrast agents show the transient circulation lifetime and poor blood-brain barrier (BBB) permeability, which seriously hamper their abilities in tumor visualization. In this work, red fluorescent carbonized polymer dots (CPDs) were systematically investigated with respect to their BBB-penetration ability. In summary, CPDs possess long excitation/emission wavelengths, low toxicity, high photostability, and excellent biocompatibility. CPDs exhibit high internalization in glioma cells in time- and dose-dependent procedures, and internalized CPDs locate mainly in endolysosomal structures. In vitro and in vivo studies confirmed the BBB permeability of CPDs, contributing to the early stage diagnosis of brain disorders and the noninvasive visualization of the brain tumor without compromised BBB. Furthermore, owing to the high tumor to normal tissue ratio of CPDs under ex vivo conditions, our nanoprobe holds the promise to guide brain-tumor resection by real-time fluorescence imaging during surgery.
