Abstract
Two azobenzene α-cyclodextrin based nanovalves are designed, synthesized and assembled on mesoporous silica nanoparticles. Under aqueous conditions, the cyclodextrin cap is tightly bound to the azobenzene moiety and capable of holding back loaded cargo molecules. Upon irradiation with a near-UV light laser, trans to cis-photoisomerization of azobenzene initiates a dethreading process, which causes the cyclodextrin cap to unbind followed by the release of cargo. The addition of a bulky stopper to the end of the stalk allows this design to be reversible; complete dethreading of cyclodextrin as a result of unbinding with azobenzene is prevented as a consequence of steric interference. As a result, thermal relaxation of cis- to trans-azobenzene allows for the rebinding of cyclodextrin and resealing of the nanopores, a process which entraps the remaining cargo. Two stalks were designed with different lengths and tested with alizarin red S and propidium iodide. No cargo release was observed prior to light irradiation, and the system was capable of multiuse. On/off control was also demonstrated by monitoring the release of cargo when the light stimulus was applied and removed, respectively.

Abstract
Novel DNA-gated mesoporous silica nanoparticle (MSN) vehicles functionalized with disulfide-linked acridinamine intercalators are constructed for multi-responsive controlled release. The DNA-gated MSN vehicles release cargo encapsulated in the MSN pores under different stimuli, including disulfide reducing agents, elevated temperature, and deoxyribonuclease I (DNase I), for codelivery of drugs and DNA/genes in different forms. Furthermore, the cascade release of encapsulated and intercalative drugs is controlled by AND logic gates in combination of dual stimuli. The ingeniously designed DNA-gated MSN vehicles integrates multiple responses and AND logic gate operations into a single smart nanodevice not only for codelivery of drugs and DNA/genes but also for cascade release of two drugs and has promising biological applications to meet diverse requirements of controlled release.

Abstract
AbstractFunctionalized mesoporous MCM-41 silica was subjected to adsorption and release studies of encapsulated guest molecules of three chosen dyes. These mesoporous systems were composed of three different capping reagents introduced by grafting method on the silica surface to control the release of dye molecules at two different pH values. The amounts of dyes adsorbed on the silica surface were measured using ultraviolet-visible (UV-VIS) spectrophotometry. The efficiency of grafting was calculated on the basis of differential thermal analysis (TG) results and elemental analysis. The release profiles were determined for all obtained systems using USP Dissolution Apparatus 2. Adsorption of the two azo dyes used was the most efficient after the positively charged functionalization and lower after functionalization with neutral and negatively charged capping reagents, while the phthalocyanine dye adsorption was almost functionalization-independent. Grafting efficiency was the highest for neutral capping reagent and much lower for electrically charged molecules of other reagents. Release studies showed clearly that desorption was pH-dependent for azo dyes and pH independent for Alcian Blue. The adsorption and release seem to be connected with the electrical charge of all constituents of these systems. Results obtained can be used for further analysis of different electrically charged molecules.

Abstract
Helical propulsion is at the heart of locomotion strategies utilized by various natural and artificial swimmers. We used experimental observations and a numerical model to study the various fluctuation mechanisms that determine the performance of an externally driven helical propeller as the size of the helix is reduced. From causality analysis, an overwhelming effect of orientational noise at low length scales is observed, which strongly affects the average velocity and direction of motion of a propeller. For length scales smaller than a few micrometers in aqueous media, the operational frequency for the propulsion system would have to increase as the inverse cube of the size, which can be the limiting factor for a helical propeller to achieve locomotion in the desired direction.

Abstract
Capsules with a shell made out of nanoparticles, so-called colloidosomes, are very interesting for controlled encapsulation and release because of their selectively permeable shell, their mechanical stability, and the possibility to make them from many materials. Here, we report the creation of complex colloidosomes that can release encapsulated cargo on-demand in single or multiple release events. Unprecedented on-demand, multiple release is achieved by incorporating functional nanoparticles within the colloidosome hollow core. The entrapped nanoparticles enable pH-triggered release by either swelling to rupture the capsule shell in one single event or desorbing on-demand cargo molecules initially adsorbed on their surface. Implementation of such mechanisms in capsules with magnetically responsive shells enabled the creation of colloidosomes exhibiting unique spatiotemporal control of cargo release.

Abstract
The incorporation of silica nanoparticles into drug delivery vehicles, and other nanotech platforms, has experienced rapid and significant growth over the past decade. However, as these nanoparticle-based systems become more and more complex, the methods used to analyze these systems have evolved at a comparatively much slower pace, resulting in the need for researchers to expand their toolbox and devise new strategies to characterize these materials. This article describes how X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) were recently employed in the analysis of two separate drug delivery systems which contain organic compounds covalently attached to the surfaces of silica nanoparticles. These techniques provided a deluge of qualitative and quantitative information about these drug delivery systems, and have several clear advantages over more common characterization procedures such as Fourier transform infrared spectroscopy (FT-IR) and solid state nuclear magnetic resonance (SSNMR). Thus, XPS and ToF-SIMS should be an integral component of the standard characterization protocol for any nanoparticle-based assemblies-particularly silica-based drug delivery systems-as this field of research continues to develop.

Abstract
The preparation of a DNA rotaxane consisting of a circular nucleic acid interlocked, through hybridization, on a nucleic acid axle and stoppered by two 10-nm-sized Au nanoparticles (NPs) is described. By the tethering of 5-nm- or 15-nm-sized Au NPs on the ring, the supramolecular structure of the rotaxane is confirmed. Using nucleic acids as "fuels" and "anti-fuels", the cyclic and reversible transition of the rotaxane ring across two states is demonstrated. By the functionalization of the ring with fluorophore-modified nucleic acids in different orientations, the transitions of the rings between the sites are followed by fluorescence quenching or surface-enhanced fluorescence. The experimental results are supported by theoretical modeling.

Although cargo size plays an important role in cargo loading, cargo charge-type does not appear to have any significant influence on the amount of cargo loading or its release. These findings open up the possibility of using pillar[n]arene and its derivatives for the formation of robust and dynamic nanosystems that are capable of performing useful functions.

Abstract
Polymeric micelles (∼10 nm) have been prepared from the amphiphilic oligomer comprising oligomeric polystyrene as the hydrophobic inner core and half of EDTA (-N(CH₂COOH)₂) as the hydrophilic outermost shell. After chelating cisplatin with -N(CH₂COOH)₂ in water, polymeric micelles containing Pt on the spherical surface have been easily obtained. Since the chelate group is introduced into the amphiphilic oligomer as the terminal group by a RAFT agent, the chelation of cisplatin with PS(COOH)₂ is almost stoichiometric. The drug carrier based on PS(COOH)₂ showed a high loading efficiency (>70%) towards cisplatin. The release of the therapeutic Pt from the cisplatin-loaded composites (PS(COOH)₂-Pt) triggered under weak acidic conditions resulted in good Pt-release and accumulation in tumor cells. Both in vitro and in vivo, the chelated cisplatin inhibited Sk-Br3 cancer more effectively than the intact cisplatin does. Furthermore, neither PS(COOH)₂ nor PS(COOH)₂-Pt showed obvious systematic toxicity.

Abstract
Synthesis of class II hybrid silica materials requires the formation of covalent linkage between organic moieties and inorganic frameworks. The requirement that organosilylating agents be present to provide the organic part limits the synthesis of functional inorganic oxides, however, due to the water sensitivity and challenges concerning purification of the silylating agents. Synthesis of hybrid materials with stable molecules such as simple alcohols, rather than with these difficult silylating agents, may therefore provide a path to unprecedented functionality. Herein, we report the novel functionalization of silica with organic alcohols for the first time. Instead of using hydrolyzable organosilylating agents, we used stable organic alcohols with a Zn(II) catalyst to modify the surface of a recently discovered highly reactive macro-mesoporous hydrogen silsesquioxane (HSQ, HSiO1.5) monolith, which was then treated with water with the catalyst to form surface-functionalized silica. These materials were comprehensively characterized with FT-IR, Raman, solid-state NMR, fluorescence spectroscopy, thermal analysis, elemental analysis, scanning electron microscopy, and nitrogen adsorption-desorption measurements. The results obtained from these measurements reveal facile immobilization of organic moieties by dehydrogenative addition onto surface silane (Si-H) at room temperature with high loading and good tolerance of functional groups. The organic moieties can also be retrieved from the monoliths for recycling and reuse, which enables cost-effective and ecological use of the introduced catalytic/reactive surface functionality. Preservation of the reactivity of as-immobilized organic alcohols has been confirmed, moreover, by successfully performing copper-catalyzed azide-alkyne cycloaddition (CuAAC) "click" reactions on the immobilized silica surfaces.

Abstract
Encapsulation systems are urgently needed both as micrometer and sub-micrometer capsules for active chemicals' delivery, to encapsulate biological objects and capsules immobilized on surfaces for a wide variety of advanced applications. Methods for encapsulation, prolonged storage and controllable release are discussed in this review. Formation of stimuli responsive systems via layer-by-layer (LbL) assembly, as well as via mobile chemical bonding (hydrogen bonds, chemisorptions) and formation of special dynamic stoppers are presented. The most essential advances of the systems presented are multifunctionality and responsiveness to a multitude of stimuli - the possibility of formation of multi-modal systems. Specific examples of advanced applications - drug delivery, diagnostics, tissue engineering, lab-on-chip and organ-on-chip, bio-sensors, membranes, templates for synthesis, optical systems, and antifouling, self-healing materials and coatings - are provided. Finally, we try to outline emerging developments.

Abstract
Ruthenium(II) polypyridyl complexes have emerged both as promising probes of DNA structure and as anticancer agents because of their unique photophysical and cytotoxic properties. A key consideration in the administration of those therapeutic agents is the optimization of their chemical reactivities to allow facile attack on the target sites, yet avoid unwanted side effects. Here, we present a drug delivery platform technology, obtained by grafting the surface of mesoporous silica nanoparticles (MSNPs) with ruthenium(II) dipyridophenazine (dppz) complexes. This hybrid nanomaterial displays enhanced luminescent properties relative to that of the ruthenium(II) dppz complex in a homogeneous phase. Since the coordination between the ruthenium(II) complex and a monodentate ligand linked covalently to the nanoparticles can be cleaved under irradiation with visible light, the ruthenium complex can be released from the surface of the nanoparticles by selective substitution of this ligand with a water molecule. Indeed, the modified MSNPs undergo rapid cellular uptake, and after activation with light, the release of an aqua ruthenium(II) complex is observed. We have delivered, in combination, the ruthenium(II) complex and paclitaxel, loaded in the mesoporous structure, to breast cancer cells. This hybrid material represents a promising candidate as one of the so-called theranostic agents that possess both diagnostic and therapeutic functions.

Abstract
Efficient and safe drug delivery has always been a challenge in medicine. The use of nanotechnology, such as the development of nano drug delivery systems (DDS), has received great attention with high enthusiasm owing to the potential that nanocarriers can theoretically act as "magic bullets" and selectively target affected organs and cells while sparing normal tissues. The family of nano DDS includes conventional nano drug delivery materials such as lipids and polymers that have been scaled to the nanometer size range. With the rapid development of synthesis and characterization techniques for engineered nanomaterials, new DDS platforms have emerged, including inorganic based nanocarriers, such as mesoporous silica nanoparticles (MSNP). MSNP are able to act as a multifunctional delivery platform that is capable of delivering therapeutic elements to a variety of disease models (especially cancer) at cellular and in vivo levels. Furthermore, MSNP have shown to be exceptional delivery platforms capable of protectively packaging hydrophobic and hydrophilic drug molecules as well as other therapeutic elements for controlled on-demand delivery. In addition, MSNP have demonstrated the capability to image the delivery site for theranostic purposes. These functionalities have led to the development of MSNP as novel multifunctional nanocarriers, and therefore provide them with unique advantages compared to other nanocarriers.

Abstract
The remarkable progress of nanotechnology and its application in biomedicine have greatly expanded the ranges and types of biomaterials from traditional organic material-based nanoparticles (NPs) to inorganic biomaterials or organic/inorganic hybrid nanocomposites due to the unprecedented advantages of the engineered inorganic material-based NPs. Colloidal mesoporous silica NPs (MSNs), one of the most representative and well-established inorganic materials, have been promoted into biology and medicine, and shifted from extensive in vitro research towards preliminary in vivo assays in small-animal disease models. In this comprehensive review, the recent progresses in chemical design and engineering of MSNs-based biomaterials for in vivo biomedical applications has been detailed and overviewed. Due to the intrinsic structural characteristics of elaborately designed MSNs such as large surface area, high pore volume and easy chemical functionalization, they have been extensively investigated for therapeutic, diagnostic and theranostic (concurrent diagnosis and therapy) purposes, especially in oncology. Systematic in vivo bio-safety evaluations of MSNs have revealed the evidences that the in vivo bio-behaviors of MSNs are strongly related to their preparation prodecures, particle sizes, geometries, surface chemistries, dosing parameters and even administration routes. In vivo pharmacokinetics and pharmacodynamics further demonstrated the effectiveness of MSNs as the passively and/or actively targeted drug delivery systems (DDSs) for cancer chemotherapy. Especially, the advance of nano-synthetic chemistry enables the production of composite MSNs for advanced in vivo therapeutic purposes such as gene delivery, stimuli-responsive drug release, photothermal therapy, photodynamic therapy, ultrasound therapy, or anti-bacteria in tissue engineering, or as the contrast agents for biological and diagnostic imaging. Additionally, the critical issues and potential challenges related to the chemical design/synthesis of MSNs-based "magic bullet" by advanced nano-synthetic chemistry and in vivo evaluation have been discussed to highlight the issues scientists face in promoting the translation of MSNs-based DDSs into clinical trials.

Abstract
MSNs have attracted increasing interest as drug carriers due to promising in vivo results in small-animal disease models, especially related to cancer therapy. In most cases small hydrophobic drugs have been used, but recent in vitro studies demonstrate that MSNs are highly interesting for gene delivery applications. This review covers recent advances related to the therapeutic use of mesoporous silica nanoparticles (MSNs) administered intravenously, intraperitoneally or locally. We also cover the use of MSNs in alternative modes of therapy such as photodynamic therapy and multidrug therapy. We further discuss the current understanding about the biodistribution and safety of MSNs. Finally, we critically discuss burning questions especially related to experimental design of in vivo studies in order to enable a fast transition to clinical trials of this promising drug delivery platform.

Abstract
This chapter describes the different strategies developed so far by the biomedical scientific community aimed at designing smart drug-delivery nanosystems whose features and functionality can be tailored attending to specific clinical needs. Among inorganic carriers, we outline recent advances in mesoporous silica nanoparticles (MSNPs) as multi-functional nanoplatforms to design smart drug-delivery devices. MSNPs can be modified by targeting moieties to deliver specifically the desired drugs into unhealthy cells. Polymeric coatings can be used to provide the system of “stealth” properties and/or stimuli-responsive drug-delivery capability. The synergistic combination of magnetic nanoparticles (mNPs) with MSNPs provides the system with an added value, the possibility of using hyperthermia treatment combined with chemotherapy to increase the antitumor capability of the system or even performing magnetic resonance imaging. MSNPs can be functionalized with molecular nanogates capping the pore outlets to prevent premature release of the cargo before reaching the target cells. The application of a given stimulus (pH change, light, magnetic field, redox potential, etc.) would promote the nanogate removal, thus triggering the drug release. The achievements derived from in vitro and in vivo experiments, which are encouraging the biomedical community to move the MSNPs platforms into clinical trials, are also reviewed.

Abstract
Blending molecular and supramolecular advances with materials science has resulted in recent years in the development of new organic-inorganic hybrid materials displaying innovative functionalities. One appealing concept in this field is the development of gated nanodevices. These materials are prepared by grafting molecular or supramolecular caps onto the external surface of mesoporous inorganic scaffolds loaded with a particular cargo. The caps or "gates" can then be opened and the cargo delivered at will upon the application of a given stimulus. In this Account, we report some of the recent advances we have made in designing such materials for drug delivery and as new chromo-fluorogenic probes. For controlled release applications, we have prepared capped hybrid mesoporous supports capable of being selectively opened by applying certain physical and chemical stimuli. We report examples of gated materials opened by changes in pH (using polyamines as caps), light (employing spiropyran derivatives or gold nanoparticles), and temperature (using selected paraffins). We also report gated materials opened by enzymes that cleave capping molecules based on lactose, hydrolyzed starch, and peptides. The use of enzymes is especially appealing because molecular caps built of enzyme-specific sequences made of peptides or other cleavable molecules could allow on-command delivery of drugs and biomolecules in specialized contexts. In the second part of the manuscript, we revisit the possibility of using hybrid gated nanomaterials as sensory systems. In such systems, when target analytes interact with the cap, their presence triggers the transport of a dye from pores to the solution, resulting in a chromo-fluorogenic signal that allows their detection. Two approaches are possible. In the first one, pores remain open and the dye can diffuse into the solution, until the presence of a target analyte binds to receptors in the caps and closes the gate. In the second approach, the caps are closed and the presence of a target analyte induces pore opening and dye delivery. One of the most interesting properties of these sensory hybrid materials is their inherent amplification features, because few target analyte molecules can modulate the transport of a significant amount of dye molecules within the porous network. We describe such systems for the recognition and sensing of anionic (ATP, long-chain carboxylates, anionic surfactants, borate, and oligonucleotides), cationic (methylmercury), and neutral (nerve agent simulants and sulfathiazole) species.

Abstract
A nanogate composed of two iminodiacetic acid (IDA) molecules and a metal ion latch was designed, synthesized, and assembled on mesoporous silica nanoparticles. This gating mechanism is capable of storing and releasing metal ions and molecules trapped in the pores. Pore openings derivatized with IDA can be latched shut by forming a bis-IDA chelate complex with a metal ion. This system was tested by loading with Hoechst 33342 as the probe cargo molecule, and latching with cobalt, nickel, or calcium metal ions. No cargo release was observed in a neutral aqueous environment, but both cargoes were delivered after acid stimulation and/or the addition of a competitively binding ligand.

Abstract
The pursuit to achieve miniaturization has tantalized researchers across the fields of chemistry, physics, biology, materials science and engineering for over half a century because of its many alluring potential applications. As alternatives to traditional "top-down" manufacturing, "bottom-up" approaches, originating from the (supra)molecular level, have enabled researchers to develop switches which can be manipulated on surfaces at nanoscale dimensions with deft precision using simple external triggers. Once on surfaces, these organic switches have been shown to modulate both the physical and chemical surface properties. In this Progress Report, we shed light on recent advances made in our laboratories towards integrated systems using all-organic switches on a variety of substrates. Design concepts are revealed, as well as the overall impact of all-organic switches on the properties of their substrates, while emphasizing the considerable promise and formidable challenges these advanced composite materials pose when it comes to conferring function on them.
