Abstract
Hollow structures have demonstrated great potential in drug delivery owing to their privileged structure, such as high surface-to-volume ratio, low density, large cavities, and hierarchical pores. In this review, we provide a comprehensive overview of hollow structured materials applied in targeting recognition, smart response, and drug release, and we have addressed the possible chemical factors and reactions in these three processes. The advantages of hollow nanostructures are summarized as follows: hollow cavity contributes to large loading capacity; a tailored structure helps controllable drug release; variable compounds adapt to flexible application; surface modification facilitates smart responsive release. Especially, because the multiple physical barriers and chemical interactions can be induced by multishells, hollow multishelled structure is considered as a promising material with unique loading and releasing properties. Finally, we conclude this review with some perspectives on the future research and development of the hollow structures as drug carriers.

Abstract
Over the past few decades, rapid advances of nucleic acid nanotechnology always drive the development of nanoassemblies with programmable design, powerful functionality, excellent biocompatibility and outstanding biosafety. Nowadays, nucleic acid-based self-assembling nanocarriers (NASNs) play an increasingly greater role in the research and development in biomedical studies, particularly in drug delivery, release and targeting. In this review, NASNs are systematically summarized the strategies cooperated with their broad applications in drug delivery. We first discuss the self-assembling methods of nanocarriers comprised of DNA, RNA and composite materials, and summarize various categories of targeting media, including aptamers, small molecule ligands and proteins. Furthermore, drug release strategies by smart-responding multiple kinds of stimuli are explained, and various applications of NASNs in drug delivery are discussed, including protein drugs, nucleic acid drugs, small molecule drugs and nanodrugs. Lastly, we propose limitations and potential of NASNs in the future development, and expect that NASNs enable facilitate the development of new-generation drug vectors to assist in solving the growing demands on disease diagnosis and therapy or other biomedicine-related applications in the real world.

Abstract
With the advent of nanotechnology, various modes of traditional treatment strategies have been transformed extensively owing to the advantageous morphological, physiochemical, and functional attributes of nano-sized materials, which are of particular interest in diverse biomedical applications, such as diagnostics, sensing, imaging, and drug delivery. Despite their success in delivering therapeutic agents, several traditional nanocarriers often end up with deprived selectivity and undesired therapeutic outcome, which significantly limit their clinical applicability. Further advancements in terms of improved selectivity to exhibit desired therapeutic outcome toward ablating cancer cells have been predominantly made focusing on the precise entry of nanoparticles into tumor cells via targeting ligands, and subsequent delivery of therapeutic cargo in response to specific biological or external stimuli. However, there is enough room intracellularly, where diverse small-sized nanomaterials can accumulate and significantly exert potentially specific mechanisms of antitumor effects toward activation of precise cancer cell death pathways that can be explored. In this review, we aim to summarize the intracellular pathways of nanoparticles, highlighting the principles and state of their destructive effects in the subcellular structures as well as the current limitations of conventional therapeutic approaches. Next, we give an overview of subcellular performances and the fate of internalized nanoparticles under various organelle circumstances, particularly endosome or lysosome, mitochondria, nucleus, endoplasmic reticulum, and Golgi apparatus, by comprehensively emphasizing the unique mechanisms with a series of interesting reports. Moreover, intracellular transformation of the internalized nanoparticles, prominent outcome and potential affluence of these interdependent subcellular components in cancer therapy are emphasized. Finally, we conclude with perspectives with a focus on the contemporary challenges in their clinical applicability.

Abstract
DNA hydrogels, which take advantage of the unique properties of functional DNA motifs, such as specific molecular recognition, programmable and high-precision assembly, multifunctionality, and excellent biocompatibility, have attracted increasing research interest in the past two decades in diverse fields, especially in biosensing and biomedical applications. The responsiveness of smart DNA hydrogels to external stimuli by changing their swelling volume, crosslinking density, and optical or mechanical properties has facilitated the development of DNA-hydrogel-based in vitro biosensing systems and actuators. Furthermore, reducing the sizes of DNA hydrogels to the micro- and nanoscale leads to better responsiveness and delivery capacity, thereby making them excellent candidates for rapid detection, in vivo real-time sensing, and drug release applications. Here, the recent progress in the development of smart DNA hydrogels and DNA microgels for biosensing and biomedical applications is summarized, and the current challenges as well as future prospects are also discussed.

Abstract
Herein, we report a ligand-reversible-shielding strategy based on the mutual shielding of dual ligands tethered to the surface of nanoparticles. To exemplify this concept, phenylboronic acid-functionalized poly(ethylene glycol)- b-poly(ε-caprolactone) (PBA-PEG-PCL) and galactose-functionalized diblock polymer (Gal-PEG-PCL) were mixed to form dual-ligand micelles (PBA/Gal). PBA and Gal residues could form a complex at pH 7.4 and mutually shield their targeting function. At pH 6.8, the binding affinity between PBA and Gal weakened, and PBA preferred to bind with the sialic acid residues on the tumor cell surface rather than to Gal on the micellar surface; furthermore, the unbound Gal recovered its targeting ability toward the asialoglycoprotein receptor. When the pH decreased from 7.4 to 6.8, enzyme-linked immunosorbent assays exhibited that the percentage of exposed Gal on the micellar surface increased 1.9-fold, and flow cytometry showed that HepG2 cellular uptake increased 4.3-fold. More importantly, this process was reversible, confirming the reversible shielding and deshielding of dual ligands. With the encapsulation of a photosensitizer, zinc phthalocyanine (ZnPc), the reversible-shielding micelles showed a 48% improvement in the half-life ( t1/2) in blood circulation, a 54% decrease in liver capture, a 40% increase in tumor accumulation, and a 10.3% improvement in the tumor inhibition rate compared to the Gal-coated irreversible micelles. This dual-ligand mutual-shielding strategy provides a new perspective on reversible tumor targeting.

Abstract
We previously proved the superiority of the ligand reversible shielding strategy based on the pH-responsive self-assembly/disassembly of gold nanoparticles through computed tomography imaging in vivo. Herein, the practicality of this strategy in tumor therapy was investigated by a ligand reversible shielding system based on a temperature-responsive polymer. The ligand biotin, cisplatin-loaded chain poly(acrylic acid)-Pt, and the shielding segment thermo-sensitive poly(N-isopropylacrylamide-co-acrylamide) (P(NIPAAm-co-AAm)) were co-modified onto the surface of gold nanostars. In the blood circulation (37 °C), the ligand was shielded by the extension of P(NIPAAm-co-AAm), whose lower critical solution temperature (LCST) is approximately 39 °C. After the nanoparticles accumulate at the tumor site by the enhanced permeability and retention (EPR) effect, the heat generated from gold nanostars upon near-infrared light irradiation would trigger the contraction of P(NIPAAm-co-AAm), thus deshielding the ligand for enhanced tumor cellular uptake. Owing to the reversible extension-contraction transformation change of P(NIPAAm-co-AAm), the reversible shielding effect on the ligand could be accomplished even if the nanoparticles return to the blood circulation. The results indicated that the system could extend blood circulation (1.6-fold at 24 h), reduce immune system clearance (28% lower), and enhance tumor accumulation (37% higher) effectively compared with the irreversible ligand shielding system by analysis of platinum. This strategy showed significantly superior tumor inhibition (11% higher) than the irreversible system. All these results make clear that the ligand reversible shielding strategy is effective and offers important references for the design of nanomaterials for improving tumor accumulation. STATEMENT OF SIGNIFICANCE: Herein, the practicality of the ligand reversible shielding strategy in tumor therapy was investigated. The ligand biotin, cisplatin loaded chain poly(acrylic acid)-Pt and the shielding segment thermo-sensitive poly(N-isopropylacrylamide-co-acrylamide) (P(NIPAAm-co-AAm) which LCST is about 39 °C) were co-modified onto the surface of gold nanostars. This well-designed NPs could shield target ligand in blood circulation (37 °C) and deshield it at tumor site (40-41 °C) reversibly. The results indicated that the system could extend blood circulation (1.6-fold at 24 h), reduce immune system clearance (28% lower) and enhance tumor accumulation (37% higher) effectively compared with the irreversible ligand shielding system by analysis of platinum. Significantly, the strategy showed superior tumor inhibition than the irreversible system (11% higher).

Abstract
The blood-brain barrier (BBB) and low targeting are major obstacles for the treatment of gliomas. Accordingly, overcoming the BBB and enhancing the targeting of drugs to the glioma area are key to achieving a good therapeutic effect. Here, we have developed the mesoporous ruthenium nanosystem RBT@MRN-SS-Tf/Apt with dual targeting function. Transferrin (Tf) and aptamer AS1411 (Apt) are grafted on the surfaces of mesoporous ruthenium nanoparticles (MRN) with high loading capacity. This is achieved via redox-cleavable disulfide bonds, serving as both a capping agent and a targeting ligand, enabling the effective penetration of the blood-brain barrier and targeting the glioma. In addition, RBT@MRN-SS-Tf/Apt can specifically kill glioma cells in vitro and in vivo. Moreover, anti-tumor drugs [Ru(bpy)2(tip)]2+ (RBT) will produce reactive oxygen species and induce apoptosis of tumor cells under laser irradiation, providing photodynamic therapy (PDT) for the treatment of gliomas, and further prolonging the median survival period. The study shows that this chemical photodynamic therapy nanosystem can be used as an efficient and powerful synergistic system for the treatment of brain tumors and other brain diseases of the central nervous system. STATEMENT OF SIGNIFICANCE: In order to overcome the blood-brain barrier and low targeting, and enhance the anti-glioma activities of nanodrugs. We have developed RBT@MRN-SS-Tf/Apt with dual targeting function. It is achieved release drug via redox-cleavable disulfide bonds, and enable the effective penetration of the blood-brain barrier and targeting the glioma. Moreover, anti-tumor drugs RBT will produce reactive oxygen species and induce apoptosis of tumor cells under laser irradiation, providing photodynamic therapy (PDT) for the treatment of gliomas, and further prolonging the median survival period. Therefore, this chemical photodynamic therapy nanosystem can be used as an efficient and powerful synergistic system for the treatment of brain tumors and other brain diseases of the central nervous system.

Abstract
Combined chemo-photothermal therapy is attracting increasing attention in the treatment of cancers. In this work, PEGylated mesoporous SiO2-coated gold nanostars (GNS@mSiO2-PEG) were synthesised without using the cytotoxic surfactant cetyltrimethylammonium bromide as the template. Mesoporous nanostructures were obtained by poly(vinylpyrrolidone) protection of the outer silica shell and NaOH etching of the inner shell. GNS@mSiO2-PEG exhibited good dispersity in medium and excellent photothermal effects. Loading capacity for the anticancer drug doxorubicin (DOX) was ∼17.9%, and the drug release profile was pH- and light-responsive. In vitro studies revealed that the as-prepared nanocomposites featured good biocompatibility. Furthermore, the nanocomposites were readily internalised by cancer cells, and a combined chemo-photothermal therapy assay revealed that DOX-loaded GNS@mSiO2-PEG have a higher therapeutic efficiency than individual therapies, demonstrating suitable synergistic effects.

Abstract
Negatively charged surface-modified drug delivery systems are promising for in vivo applications as they have more tendency to accumulate in tumor tissues. However, the inefficient cell uptake of these systems restricts their final therapeutic performance. Here, we have fabricated a receptor-mediated surface charge inversion nanoparticle made of undecylenic acid modified, thermally hydrocarbonized porous silicon (UnTHCPSi) nanoparticles core and sequentially modified with polyethylenimine (PEI), methotrexate (MTX), and DNA aptamer AS1411 (herein termed as UnTHCPSi-PEI-MTX@AS1411) for enhancing the cell uptake of nucleolin-positive cells. The efficient interaction of AS1411 and the relevant receptor nucleolin caused the disintegration of the negative-charged AS1411 surface. The subsequent surface charge inversion and exposure of the active targeting ligand, MTX, enhanced the cell uptake of the nanoparticles. On the basis of this synergistic effect, the UnTHCPSi-PEI-MTX@AS1411 (hydrodynamic diameter is 242 nm) were efficiently internalized by nucleolin-positive MDA-MB-231 breast cancer cells, with an efficiency around 5.8 times higher than that of nucleolin-negative cells (NIH 3T3 fibroblasts). The receptor competition assay demonstrated that the major mechanism (more than one-half) of the internalized nanoparticles in MDA-MB-231 cells was due to the receptor-mediated surface charge inversion process. Finally, after loading of sorafenib, the nanosystem showed efficient performance for combination therapy with an inhibition ratio of 35.6%.
