Abstract
Stimuli-responsive nano-assemblies from amphiphilic macromolecules could undergo controlled structural transformations and generate diverse macroscopic phenomenon under stimuli. Due to the controllable responsiveness, they have been applied for broad material and biomedical applications, such as biologics delivery, sensing, imaging, and catalysis. Understanding the mechanisms of the assembly-disassembly processes and structural determinants behind the responsive properties is fundamentally important for designing the next generation of nano-assemblies with programmable responsiveness. In this review, we focus on structural determinants of assemblies from amphiphilic macromolecules and their macromolecular level alterations under stimuli, such as the disruption of hydrophilic-lipophilic balance (HLB), depolymerization, decrosslinking, and changes of molecular packing in assemblies, which eventually lead to a series of macroscopic phenomenon for practical purposes. Applications of stimuli-responsive nano-assemblies in delivery, sensing and imaging were also summarized based on their structural features. We expect this review could provide readers an overview of the structural considerations in the design and applications of nanoassemblies and incentivize more explorations in stimuli-responsive soft matters.

Abstract
Cell-penetrating peptides (CPPs), developed for more than 30 years, are still being extensively studied due to their excellent delivery performance. Compared with other delivery vehicles, CPPs hold promise for delivering different types of drugs. Here, we review the development process of CPPs and summarize the composition and classification of the CPP-based delivery systems, cellular uptake mechanisms, influencing factors, and biological barriers. We also summarize the optimization routes of CPP-based macromolecular drug delivery from stability and targeting perspectives. Strategies for enhanced endosomal escape, which prolong its half-life in blood, improved targeting efficiency and stimuli-responsive design are comprehensively summarized for CPP-based macromolecule delivery. Finally, after concluding the clinical trials of CPP-based drug delivery systems, we extracted the necessary conditions for a successful CPP-based delivery system. This review provides the latest framework for the CPP-based delivery of macromolecular drugs and summarizes the optimized strategies to improve delivery efficiency.

Abstract
A bioresponsive polymeric nanocarrier for drug delivery is able to alter its physical and physicochemical properties in response to a variety of biological signals and pathological changes, and can exert its therapeutic efficacy within a confined space. These nanosystems can optimize the biodistribution and subcellular location of therapeutics by exploiting the differences in biochemical properties between tumors and normal tissues. Moreover, bioresponsive polymer-based nanosystems could be rationally designed as precision therapeutic platforms by optimizing the combination of responsive elements and therapeutic components according to the patient-specific disease type and stage. In this review, recent advances in smart bioresponsive polymeric nanosystems for cancer chemotherapy and immunotherapy will be summarized. We mainly discuss three categories, including acidity-sensitive, redox-responsive, and enzyme-triggered polymeric nanosystems. The important issues regarding clinical translation such as reproducibility, manufacture, and probable toxicity, are also commented.

Abstract
Coating nanosized anticancer drug delivery systems (DDSs) with poly(ethylene glycol) (PEG), the so-called PEGylation, has been proven an effective method to enhance hydrophilicity, aqueous dispersivity, and stability of DDSs. What is more, as PEG has the lowest level of protein absorption of any known polymer, PEGylation can reduce the clearance of DDSs by the mononuclear phagocyte system (MPS) and prolong their blood circulation time in vivo. However, the “stealthy” characteristic of PEG also diminishes the uptake of DDSs by cancer cells, which may reduce drug utilization. Therefore, dynamic protection strategies have been widely researched in the past years. Coating DDSs with PEG through dynamic covalent or noncovalent bonds that are stable in blood and normal tissues, but can be broken in the tumor microenvironment (TME), can achieve a DePEGylation-based “tumor-triggered” targeting or intracellular drug release, which can effectively improve the utilization of drugs and reduce their side effects. In this review, the stimuli and methods of “tumor-triggered” targeting or intracellular drug release, based on DePEGylation, are summarized. Additionally, the targeting and intracellular controlled release behaviors of the DDSs are briefly introduced.

Abstract
Targeted delivery of chemotherapeutic drugs can improve their therapeutic efficiency by localizing their toxic effects at the diseased site. This is often achieved either by direct conjugation of drugs to antibodies targeting overexpressed receptors on cancer cells (antibody-drug conjugates/ADCs) or by conjugating antibodies to nanoparticles bearing drugs (antibody-nanoparticle conjugates/ANCs). Here, we report a platform for utilizing hinge cysteines on antigen-binding fragment (Fab') of an anti-CD4 antibody for site-specific conjugation to nanoparticles giving rise to anti-CD4 Fab'-nanoparticle conjugates (Fab'-NCs). We demonstrate a convenient route for obtaining functional anti-CD4 Fab' from full-length antibody and examine the targeted delivery efficiencies of anti-CD4 Fab'-NCs vs ANCs for selective delivery to CD4high mT-ALL cells. Our results indicate that higher avidity of full-length anti-CD4 antibody, i.e., protein alone translated to higher binding ability to CD4high mT-ALL cells in comparison with anti-CD4 Fab' alone. However, the targeted delivery efficiency of anti-CD4 Fab'-NCs was comparable to ANCs indicating that the avidity of Fab' is restored in a nanoparticle-conjugate format. Fab'-NCs are equally capable of achieving targeted drug delivery to CD4high T-cells as ANCs and are a versatile alternative to ANCs by offering site-selective modification strategy while retaining their advantages.

Abstract
Proteases have a fundamental role in maintaining physiological homeostasis, but their dysregulation results in severe activity imbalance and pathological conditions, including cancer onset, progression, invasion, and metastasis. This striking importance plus superior biological recognition and catalytic performance of proteases, combining with the excellent physicochemical characteristics of nanomaterials, results in enzyme-activated nano-drug delivery systems (nanoDDS) that perform theranostic functions in highly specific response to the tumor phenotype stimulus. In the tutorial review, the key advances of protease-responsive nanoDDS in the specific diagnosis and targeted treatment for malignancies are emphatically classified according to the effector biomolecule types, on the premise of summarizing the structure and function of each protease. Subsequently, the incomplete matching and recognition between enzyme and substrate, structural design complexity, volume production, and toxicological issues related to the nanocomposites are highlighted to clarify the direction of efforts in nanotheranostics. This will facilitate the promotion of nanotechnology in the management of malignant tumors.

Abstract
The emergence of nanomaterials for drug delivery provides the opportunity to avoid the side effects of systemic drug administration and injury caused by the removal of tumors, delivering great promise for future cancer treatments. However, the efficacy of current nano drugs is not significantly better than that of the original drug treatments. The important reason is that nano drugs enter the tumor vasculature, remaining close to the blood vessels and unable to enter the tumor tissue or tumor cells to complete the drug delivery process. The low efficiency of drug penetration into tumors has become a bottleneck restricting the development of nano-drugs. Herein, we present a systematic overview of recent advances on the design of nano-drug carriers in drug delivery systems for enhancing drug penetration into tumors. The review is organized into four sections: The drug penetration process in tumor tissue includes paracellular and transcellular transport, which is summarized first. Strategies that promote tumor penetration are then introduced, including methods of remodeling the tumor microenvironment, charge inversion, dimensional change, and surface modification of ligands which promote tissue penetration. Conclusion and the prospects for the future development of drug penetration are finally briefly illustrated. The review is intended to provide thoughts for effective treatment of cancer by summarizing strategies for promoting the endocytosis of nano drugs into tumor cells.

Abstract
Gene therapy provides a promising strategy for curing monogenetic disorders and complex diseases. However, there are challenges associated with the use of viral delivery vectors. The advent of nanomedicine represents a quantum leap in the application of gene therapy. Recent advances in stimulus-responsive nonviral nanocarriers indicate that they are efficient delivery systems for loading and unloading of therapeutic nucleic acids. Some nanocarriers are responsive to cues derived from the internal environment, such as changes in pH, redox potential, enzyme activity, reactive oxygen species, adenosine triphosphate, and hypoxia. Others are responsive to external stimulations, including temperature gradients, light irradiation, ultrasonic energy, and magnetic field. Multiple stimuli-responsive strategies have also been investigated recently for experimental gene therapy.

Abstract
The limited availability of nasopharyngeal carcinoma-related progression biomarker array kits that offer physicians comprehensive information is disadvantageous for monitoring cancer progression. To develop a biomarker array kit, systematic identification and differentiation of a large number of distinct molecular surface-enhanced Raman scattering (SERS) reporters with high spectral temporal resolution is a major challenge. To address this unmet need, we use the chemistry of metal carbonyls to construct a series of unique SERS reporters with the potential to provide logical and highly multiplex information during testing. In this study, we report that geometric control over metal carbonyls on nanotags can produce 14 distinct barcodes that can be decoded unambiguously using commercial Raman spectroscopy. These metal carbonyl nanobarcodes are tested on human blood samples and show strong sensitivity (0.07 ng/mL limit of detection, average CV of 6.1% and >92% degree of recovery) and multiplexing capabilities for MMPs.

Abstract
Even though various techniques have been developed thus far for targeted delivery of therapeutics, design and fabrication of cancer biomarker-triggered disintegrable nanogels, which are exclusively composed of nucleic acid macromolecules, are still challenging nowadays. Here, we describe for the first time our creation of intelligent DNA nanogels whose backbones are sorely disintegrable by flap endonuclease 1 (FEN1), an enzymatic biomarker that is highly overexpressed in most cancer cells but not in their normal counterparts. It is the catalytic actions of intracellular FEN1 on bifurcated DNA structures that lead to the cancer-specific disintegration of our DNA nanogels and controlled release of drugs in target cancer cells. Consequently, the brand-new strategies introduced in the current report could break new ground in designing drug carriers for eliminating unwanted side effects of chemotherapeutic agents and live-cell probes for cancer risk assessment, diagnosis, and prognosis.

Abstract
Understanding the cellular uptake mechanism of materials is of fundamental importance that would be beneficial for materials design with enhanced biological functions. Herein, we report the interplay of pharmacological and genetic approaches to minimize the possible misinterpretation on cellular uptake mechanism. A library of amphiphilic polymers was used as a model system to evaluate the reliability of such methodological interplay. To probe the cellular uptake of amphiphilic polymers, we utilized an orthogonal end-group labeling strategy to conjugate one fluorescent molecule on each polymer chain. The results from the methodological interplay with these labeled polymers revealed the off-target effects of dynasore, a well-known dynamin inhibitor. Instead of dynamin, actin was found to be an essential cellular component during the cellular uptake of these amphiphilic polymers. Our study demonstrates the importance of interplaying pharmacological and genetic approaches when evaluating the endocytic mechanism of functional materials, providing insights on understanding the cellular uptake of future therapeutic materials.

Abstract
For clinical application of therapeutic gene delivery, it is urgent to develop safe and in vivo efficient delivery systems. Nowadays, gene delivery carriers based on functional peptides have attracted much attention due to their excellent biocompatibility, biodegradability and biological multifunctionality. In the present study, a star-shaped integrated functional peptide, polyhedral oligomeric silsesquioxane (POSS-(C-G-NLS-G-TAT)16, abbreviated as PP1), was synthesized through "thiol-ene" click chemistry between the TAT-G-NLS-G-C multifunctional peptide sequence and inorganic octa-diallyl POSS. Cationic PP1 was mixed with the pZNF580 plasmid to obtain stable binary gene complexes (BCPs) with membrane penetrating and nucleus targeting functions. In order to improve BCPs' biocompatibility, cellular uptake, and endosome escape, they were further modified using an anionic polymer of PLL-g-CAGW21%-g-Acon (n = 47%, 57% and 64%) having an EC targeting ligand (CAGW peptide) and a charge reversal moiety (cis-aconitic amide) through electrostatic absorption to obtain ternary gene complexes (TCPs). By adjusting the weight ratio of PP1/pZNF580 plasmid/PLL-g-CAGW21%-g-Acon to 5/1/1.25, TCPs-1 with n = 47%, TCPs-2 with n = 57% and TCPs-3 with n = 64% exhibited a neutral zeta potential and suitable particle size; thus they were used for further biological evaluation. Compared with BCPs (5/1 weight ratio of PP1/pZNF580 plasmid), TCPs exhibited high hemocompatibility and cytocompatibility; more interestingly, they also showed significantly enhanced gene delivery efficiency. The TCP groups achieved perfect transfection effects in the proliferation and migration of human umbilical vein endothelial cells (HUVECs), and especially high neovascularization in vitro and in vivo. Our results demonstrated that the high graft ratio of cis-aconitic amide provided benefits of high biocompatibility and gene delivery efficiency, and the TCPs-3 group showed the optimized transfection efficiency among the three groups. Importantly, HUVECs transfected with TCPs-3 exhibited an outstanding ability to enhance angiogenesis in vivo. In brief, this multifunctional ternary gene system with the EC targeting ligand and membrane penetrating, charge reversal and nucleus targeting functions is a promising platform for the transfection of HUVECs, and may be useful for the treatment of cardiovascular diseases in clinical applications.

Abstract
Nanomedicine has generated significant interest as an alternative to conventional cancertherapy due to the ability for nanoparticles to tune cargo release. However, while nanoparticletechnology has promised significant benefit, there are still limited examples of nanoparticles inclinical practice. The low translational success of nanoparticle research is due to the series ofbiological roadblocks that nanoparticles must migrate to be effective, including blood and plasmainteractions, clearance, extravasation, and tumor penetration, through to cellular targeting,internalization, and endosomal escape. It is important to consider these roadblocks holistically inorder to design more effective delivery systems. This perspective will discuss how nanoparticlescan be designed to migrate each of these biological challenges and thus improve nanoparticledelivery systems in the future. In this review, we have limited the literature discussed to studiesinvestigating the impact of polymer nanoparticle structure or composition on therapeutic deliveryand associated advancements. The focus of this review is to highlight the impact of nanoparticlecharacteristics on the interaction with different biological barriers. More specific studies/reviewshave been referenced where possible.

Abstract
The current limitations in the use of nanocarriers to treat constantly evolving diseases call for the design of novel and smarter drug delivery systems (DDS). Nanogels (NGs) are three-dimensional crosslinked polymers with dimensions on the nanoscale and with a great potential for use in the biomedical field. Particular interest focuses on their application as DDS to minimize severe toxic effects and increase the therapeutic index of drugs. They have recently gained attention, since they can include responsive modalities within their structure, which enable them to excerpt a therapeutic function on demand. Their bigger sizes and controlled architecture and functionality, when compared to non-crosslinked polymers, make them particularly interesting to explore novel modalities to cross biological barriers. The present review summarizes the most significant developments of NGs as smart carriers, with focus on smart modalities to cross biological barriers such as cellular membrane, tumor stroma, mucose, skin, and blood brain barrier. We discuss the properties of each barrier and highlight the importance that the NG design has on their capability to overcome them and deliver the cargo at the site of action.

Abstract
Poly(ethylene glycol) (PEG)-based nanogels are attractive for biomedical applications due to their biocompatibility, versatile end group chemistry, and ability to sterically shield encapsulated drug molecules. The characteristics of a hydrogel network govern the encapsulation and efficient delivery of drug molecules for a target application. A molecular-level description of network topology can complement experimental investigations to understand its effects on the structural properties of these nanogels. In this work, atomistic molecular simulations of heterogeneous, nonideal PEG-diacrylate (PEGDA) nanogels are presented. The effects of cross-linking density and topological features on the structural properties of PEGDA nanogels were studied. The average functionality was controlled to systematically study the effect of cross-linking density on the radius of gyration, shape, and mesh size of the nanogels. For a given average functionality, the impact of distinct network topologies on the structural properties was also studied. The aspect ratios, based on the gyration tensor, were calculated to characterize the shapes of these nanogels for different topologies. Nanogel structures with higher cross-linking densities showed a globular shape, while structures with lower cross-linking density showed shape anisotropy. The distribution and connectivity of the cross-linked junctions played a key role in determining the size and shape anisotropy of PEGDA nanogels; the number of unreacted chain ends and their connectivity directly affected the anisotropy. The mesh size, denoted by the limiting "free volume element" present in the nanogel samples, does not show a significant change with increasing average functionality. This work provides insight into the structural properties of heterogeneous hydrogels that aid the design of nonideal nanogel networks for a targeted drug delivery application.

Abstract
To maximize drug targeting to solid tumors, cancer nanomedicines with prolonged circulation times are required. To this end, poly(ethylene glycol) (PEG) has been widely used as a steric shield of nanomedicine surfaces to minimize serum protein absorption (opsonisation) and subsequent recognition and clearance by cells of the mononuclear phagocyte system (MPS). However, PEG also inhibits interactions of nanomedicines with target cancer cells, limiting the effective drug dose that can be reached within the target tumor. To overcome this dilemma, nanomedicines with stimuli-responsive cleavable PEG functionality have been developed. These benefit from both long circulation lifetimes en route to the targeted tumor as well as efficient drug delivery to target cancer cells. In this review, various stimuli-responsive strategies to dePEGylate nanomedicines within the tumor microenvironment will be critically reviewed.

Abstract
Owing to the complex and still not fully understood physiological environment, the development of traditional nanosized drug delivery systems is very challenging for precision cancer therapy. It is very difficult to control the in vivo distribution of nanoparticles after intravenous injection. The ideal drug nanocarriers should not only have stealth surface for prolonged circulation time but also possess enhanced cellular internalization in tumor sites. Unfortunately, the stealth surface and enhanced cellular uptake seem contradictory to each other. How to integrate the two opposite aspects into one system is a very herculean but meaningful task. As an alternative drug delivery strategy, chameleon-like drug delivery systems were developed to achieve long circulation time while maintaining enhanced cancer cell uptake. Such drug nanocarriers can "turn off" their internalization ability during circulation. However, the enhanced cellular uptake can be readily activated upon arriving at tumor tissues. In this way, stealth surface and enhanced uptake are of dialectical unity in drug delivery. In this review, we focus on the surface engineering of drug nanocarriers to obtain simultaneous stealth surfaces in circulation and enhanced uptake in tumors. The current strategies and ongoing developments, including programmed tumor-targeting strategies and some specific zwitterionic surfaces, will be discussed in detail.
