Abstract
Mesoporous silica nanoparticles have been broadly applied as drug delivery systems owing to their exquisite features, such as excellent textural properties or biocompatibility. However, there are various biological barriers that prevent their proper translation into the clinic, including: (1) lack of selectivity toward tumor tissues, (2) lack of selectivity for tumoral cells and (3) endosomal sequestration of the particles upon internalization. In addition, their open porous structure may lead to premature drug release, consequently affecting healthy tissues and decreasing the efficacy of the treatment. First, this review will provide a comprehensive and systematic overview of the different approximations that have been implemented into mesoporous silica nanoparticles to overcome each of such biological barriers. Afterward, the potential premature and non-specific drug release from these mesoporous nanocarriers will be addressed by introducing the concept of stimuli-responsive gatekeepers, which endow the particles with on-demand and localized drug delivery.

Abstract
Bacterial infections are the main cause of chronic infections and even mortality. In fact, due to extensive use of antibiotics and, then, emergence of antibiotic resistance, treatment of such infections by conventional antibiotics has become a major concern worldwide. One of the promising strategies to treat infection diseases is the use of nanomaterials. Among them, mesoporous silica materials (MSMs) have attracted burgeoning attention due to high surface area, tunable pore/particle size, and easy surface functionalization. This review discusses how one can exploit capacities of MSMs to design and fabricate multifunctional/controllable drug delivery systems (DDSs) to combat bacterial infections. At first, the emergency of bacterial and biofilm resistance toward conventional antimicrobials is described and then how nanoparticles exert their toxic effects upon pathogenic cells is discussed. Next, the main aspects of MSMs (e.g., physicochemical properties, multifunctionality, and biosafety) which one should consider in the design of MSM-based DDSs against bacterial infections are introduced. Finally, a comprehensive analysis of all the papers published dealing with the use of MSMs for delivery of antibacterial chemicals (antimicrobial agents functionalized/adsorbed on mesoporous silica (MS), MS-loaded with antimicrobial agents, gated MS-loaded with antimicrobial agents, MS with metal-based nanoparticles, and MS-loaded with metal ions) is provided.

Abstract
Designing a smart nanotheranostic system has recently attracted tremendous attention and is highly desirable for realizing targeted cancer therapy and early diagnosis. Herein we report the fabrication of smart nanotheranostic system using multiresponsive gatekeeping protocol of mesoporous silica nanoparticles (MSN). Acid, oxidative stress and redox sensitive manganese oxide (MnO x) coated superparamagnetic iron oxide nanoparticle (SPION) were employed as nanolids to regulate the camptothecin drug release from the channels of mesoporous silica and achieve responsive dual-mode MRI contrast. The nonvehicle showed high magnetization and T2 contrast in magnetic resonance imaging (MRI) due to the significant density of SPION onto the surface of MSN, and at the same time the MnO x shell degradation release Mn2+ which enhanced the T1MRI visualization. The efficacy of responsive drug delivery system was investigated on pancreatic cancer cells and tumor-bearing mice, and results reinforced that MnO x-SPION@MSN@CPT nonvehicle is efficacious against cancer cells. We envision that our unique and multiresponsive nanoplatform may find applications in effective delivering of imaging and therapeutic agents to wide range of diseases besides cancer.

Abstract
In the last two decades, zinc oxide (ZnO) semiconductor Quantum dots (QDs) have been shown to have fantastic luminescent properties, which together with their low-cost, low-toxicity and biocompatibility have turned these nanomaterials into one of the main candidates for bio-imaging. The discovery of other desirable traits such as their ability to produce destructive reactive oxygen species (ROS), high catalytic efficiency, strong adsorption capability and high isoelectric point, also make them promising nanomaterials for therapeutic and diagnostic functions. Herein, we review the recent progress on the use of ZnO based nanoplatforms in drug delivery and theranostic in several diseases such as bacterial infection and cancer.

Abstract
The use of a robust optical signaling probe with a high signal-to-noise ratio is important in the development of immunoassays. Lanthanide chelates are a promising material for this purpose, which provide time-resolved luminescence (TRL) due to their large Stokes shift and long luminescence lifetime. From this, they have attracted considerable interest in the in vitro diagnostics field. However, the direct use of lanthanide chelates is limited because their luminescent signal can be easily affected by various quenchers. To overcome this drawback, strategies that rely on the entrapment of lanthanide chelates inside nanoparticles, thereby enabling the protection of the lanthanide chelate from water, have been reported. However, the poor stability of the lanthanide-entrapped nanoparticles results in a significant fluctuation in TRL signal intensity, and this still remains a challenging issue. To address this, we have developed a Lanthanide chelate-Encapsulated Silica Nano Particle (LESNP) as a new immunosensing probe. In this approach, the lanthanide chelate is covalently crosslinked within the silane monomer during the silica nanoparticle formation. The resulting LESNP is physically stable and retains TRL properties of the parent lanthanide chelate. Using the probe, a highly sensitive, sandwich-based TRL immunoassay for the cardiac troponin I was conducted, exhibiting a limit of detection of 48 pg/mL. On the basis of the features of the LESNP such as TRL signaling capability, stability, and the ease of biofunctionalization, we expect that the LESNP can be widely applied in the development of TRL-based immunosensing.

Abstract
Delivering and releasing anticancer agents directly to their subcellular targets of action in a controlled manner are almost the ultimate goal of pharmacology, but it is challenging. In recent decades, plenty of efforts have been made to send drugs to tumor tissue or even specifically to cancer cells; however, at the subcellular scale, cancer cells have multiple cunning ways to hinder drugs from reaching their final action targets. Here, we demonstrate a strategy to bypass the last defense of cancer drug resistance by contolling the drug transportation and release at subcellular scale. We developed a platform based on ultrasound-degradable mesoporous nanosilicon, which allows drug delivery towards, ultrasound controlled drug release into the cell nucleus. This strategy altered the drug distribution within cells and remarkably enhanced the drug accumulation ratio at the action target, i.e. nucleus. In vitro and in vivo studies proved that this strategy reduced the drug dosage by an order of magnitude, prolonged drug retention and amplified therapeutic efficacy in tumor-bearing mice. These results offer new insights into bypassing cancer drug resistance through transport and release drugs directly to their action targets in a controlled manner.

Abstract
Here, we demonstrated a pH-responsive nanocluster based on ZnO quantum dots (QDs) and investigated its potential in drug delivery with tumor-specific accumulation. The nanoclusters were composed of small single ZnO QDs by cross-linking dicarboxyl-terminated poly(ethylene glycol) (PEG), showing high stability and biocompatibility in physiological fluids. The clustered ZnO QDs were capable of loading a large quantity of doxorubicin (DOX) via complexation and covalent interactions. After cellular uptake, the drug was efficiently released because the carrier was completely dissolved; the metal-drug complex was disassembled in response to decreasing pH in the endosomes within tumor cells. Moreover, the viability of cancer cells was significantly decreased because the ZnO QDs exhibited cytotoxicity postdissolution and preferentially killed cancerous cells compared to normal cells. Furthermore, this pH-responsive PEG-cZnO QDs cluster system may be capable of tumor homing while circulating in the blood via the enhanced permeability and retention (EPR) effect.

Abstract
Background One of the main problems in B cell lymphoma treatment is severe adverse effects and low therapeutic efficacy resulting from systemic chemotherapy. A pH-sensitive controlled drug release system based on mesoporous silica nanoparticles was constructed for targeted drug delivery to tumor cells to reduce systemic toxicity and improve the therapeutic efficacy. Methods In this study, the doxorubicin (DOX) was filled into the mesopores of the functional MSNs (DMSNs). Furthermore, rituximab was introduced as the targeted motif of functional DMSNs using an avidin-biotin bridging method to evaluate the targetability to tumor cells. Then, the cell viability and apoptosis efficiency after treatment with rituximab-conjugated DMSNs (RDMSNs) were estimated by using CCK-8 assay and flow cytometry, respectively. Additionally, the research in vivo was performed to evaluate the enhanced antitumor efficacy and the minimal toxic side effects of RDMSNs. Also, TUNEL staining assay was employed to explore the mechanism of antitumor effects of RDMSNs. Results This targeted drug delivery system exhibited low premature drug release at a physiological pH and efficient pH-responsive intracellular release under weakly acidic conditions. The in vitro tests confirmed that targeted RDMSNs could selectively adhere to the surface of lymphoma B cells via specific binding with the CD20 antigen and be internalized into CD20 positive Raji cells but few CD20 negative Jurkat cells, which leads to increased cytotoxicity and apoptosis of the DOX in Raji cells due to the release of the entrapped DOX with high efficiency in the slightly acidic intracellular microenvironment. Furthermore, the in vivo investigations confirmed that RDMSNs could efficiently deliver DOX to lymphoma B cells by pH stimuli, thus inducing cell apoptosis and inhibiting tumor growth, while with minimal toxic side effects. Conclusions This targeted and pH-sensitive controlled drug delivery system has the potential for promising application to enhance the therapeutic index and reduce the side effects of B cell lymphoma therapy.

Abstract
The application of nanotechnology to medicine constitutes a major field of research nowadays. In particular, the use of mesoporous silica and carbon nanoparticles has attracted the attention of numerous researchers due to their unique properties, especially when applied to cancer treatment. Many strategies based on stimuli-responsive nanocarriers have been developed to control the drug release and avoid premature release. Here, we focus on the use of the subtle changes of pH between healthy and diseased areas along the body to trigger the release of the cargo. In this review, different approximations of pH-responsive systems are considered: those based on the use of the host-guest interactions between the nanocarriers and the drugs, those based on the hydrolysis of acid-labile bonds and those based on supramolecular structures acting as pore capping agents.

Abstract
In this paper, we reported a ZnO quantum dots-based pH-responsive drug delivery platform for intracellular controlled release of drugs. Acid-decomposable, luminescent aminated ZnO quantum dots (QDs) were synthesized as nanocarriers with ultrasmall size (∼3 nm). The dicarboxyl-terminated poly(ethylene glycol) (PEG) had been introduced to NH2-ZnO QDs, which rendered it stable under physiological fluid. Moreover, a targeting ligand, hyaluronic acid (HA), was conjugated to ZnO QDs for specifically binding to the overexpressed glycoprotein CD44 by cancer cells. Doxorubicin (DOX) molecules were successfully loaded to PEG functionalized ZnO QDs via formation of metal-DOX complex and covalent interactions. The pH-sensitive ZnO QDs dissolved to Zn(2+) in acidic endosome/lysosome after uptake by cancer cells, which triggered dissociation of the metal-drug complex and a controlled DOX release. As result, a synergistic therapy was achieved due to incorporation of the antitumor effect of Zn(2+) and DOX.

Abstract
Stimuli-responsive carriers releasing multiple drugs have been researched for synergistic combinatorial cancer treatment with reduced side-effects. However, previously used drug carriers have limitations in encapsulating multiple drug components in a single carrier and releasing each drug independently. In this work, pH-sensitive, multimodulated, anisotropic drug carrier particles are synthesized using an acid-cleavable polymer and stop-flow lithography. The particles exhibit a faster drug release rate at the acidic pH of tumors than at physiological pH, demonstrating their potential for tumor-selective drug release. The drug release rate of the particles can be adjusted by controlling the monomer composition. To accomplish multimodulated drug release, multicompartmental particles are synthesized. The drug release profile of each compartment is programmed by tailoring the monomer composition. These pH-sensitive, multicompartmental particles are promising drug carriers enabling tumor-selective and multimodulated release of multiple drugs for synergistic combination cancer therapy.

Abstract
In this work, we employed dendrimerlike mesoporous silica nanoparticles with hierarchical pores (HPSNs) to fabricate drug delivery system bioimaging and targeted tumor therapy in vivo. N,N-phenylenebis(salicylideneimine)dicarboxylic acid (Salphdc) was used both as the gatekeeper of HPSNs via pH-responsive coordination bonds between -COOH of Salphdc and In(3+) ions and as a fluorescence imaging agent. Folic acid was then conjugated to Salphdc as the targeting unit. The results revealed that the system could deliver model drug DOX to the tumor site with high efficiency and then cause cell apoptosis and tumor growth inhibition. Moreover, the conjugated Salphdc was proved to be a promising fluorescence probe for tracing distribution of the system in vivo. The study affords a potential nanoconainer for cancer therapy and biological imaging.

Abstract
In this paper, a glucose and pH-responsive release system based on polymeric network capped mesoporous silica nanoparticles (MSN) has been presented. The poly(acrylic acid) (PAA) brush on MSN was obtained through the surface-initiated atom transfer radical polymerization (SI-ATRP) of t-butyl acrylate and the subsequent hydrolysis of the ester bond. Then the PAA was glycosylated with glucosamine to obtain P(AA-AGA). To block the pore of silica, the P(AA-AGA) chains were cross-linked through the formation of boronate esters between 4,4-(ethylenedicarbamoyl)phenylboronic acid (EPBA) and the hydroxyl groups of P(AA-AGA). The boronate esters disassociated in the presence of glucose or in acidic conditions, which lead to opening of the mesoporous channels and the release of loaded guest molecules. The rate of release could be tuned by varying the pH or the concentration of glucose in the environment. The combination of two stimuli exhibited an obvious enhanced release capacity in mild acidic conditions (pH 6.0).

Abstract
Horseradish peroxidase-immobilized magnetic mesoporous silica nanoparticles (MMSNs-HRP) have been synthesized by a NHS/EDC coupling between the amino groups of horseradish peroxidase (HRP) and the carboxyl groups on the MMSNs surface. It is found that the immobilized HRP on MMSNs still retain high activity and the MMSNs-HRP can eliminate the reactive oxygen species (ROS) in Chinese hamster ovary (CHO) cells induced by the addition of H2O2 aqueous solution. Further, the fluorescent MMSN-HRP-CD nanoparticles have been prepared by attaching biocompatible, fluorescent carbon dots (CDs) to MMSNs-HRP. We have also investigated the effect of an applied magnetic field on cellular uptake of MMSNs-HRP-CDs and found that the internalization of MMSNs-HRP-CDs by CHO cells could be enhanced within 2 hours under the magnetic field. This work provides us with a novel and efficient method to eliminate ROS in living cells by using HRP-immobilized nanoparticles.
