Abstract
Inflammatory bowel disease (IBD) is a chronic and recurrent inflammatory disease that affects the gastrointestinal tract. The major hurdles impeding IBD treatment are the low targeting efficiency and short retention time of drugs in IBD sites. Nanoparticles with specific shapes have demonstrated the ability to improve mucus retention and cellular uptake. Herein, mesoporous silica nanoparticles (MSNs) with various morphologies were used to deliver budesonide (BUD) for the treatment of IBD. The therapeutic efficacy is strongly dependent on their shapes. The system comprises different shapes of MSNs as carriers for budesonide (BUD), along with Eudragit S100 as the enteric release shell. The encapsulation of Eudragit S100 not only improved the stability of MSNs-BUD in the gastrointestinal tract but also conferred pH-responsive drug release properties. Then, MSNs efficiently deliver BUD to the colon site, and the special shape of MSNs plays a critical role in enhancing their permeability and retention in the mucus layer. Among them, dendritic MSNs (MSND) effectively reduced myeloperoxidase (MPO) activity and levels of inflammatory cytokines in the colon due to long retention time and rapid release in IBD sites, thereby enhancing the therapeutic efficacy against colitis. Given the special shapes of MSNs and pH-responsivity of Eudragit S100, BUD loaded in the voids of MSND (E@MSNs-BUD) could penetrate the mucous layer and be accurately delivered to the colon with minor side effects. This system is expected to complement current treatment strategies for the IBD.

Abstract
Nowadays, cardiovascular and cerebrovascular diseases caused by venous thromboembolism become main causes of mortality around the world. The current thrombolytic strategies in clinics are confined primarily due to poor penetration of nanoplatforms, limited thrombolytic efficiency, and extremely-low imaging accuracy. Herein, a novel nanomotor (NM) is engineered by combining iron oxide/perfluorohexane (PFH)/urokinase (UK) into liposome nanovesicle, which exhibits near-infrared/ultrasound (NIR/US) triggered transformation, achieves non-invasive vein thrombolysis, and realizes multimodal imaging diagnosis altogether. Interestingly, a three-step propelled cascade thrombolytic therapy is revealed from such intelligent NM. First, the NM is effectively herded at the thrombus site under guidance of a magnetic field. Afterwards, stimulations of NIR/US propel phase transition of PFH, which intensifies penetration of the NM toward deep thrombus dependent on cavitation effect. Ultimately, UK is released from the collapsed NM and achieves pharmaceutical thrombolysis in a synergistic way. After an intravenous injection of NM in vivo, the whole thrombolytic process is monitored in real-time through multimodal photoacoustic, ultrasonic, and color Doppler ultrasonic imagings. Overall, such advanced nanoplatform provides a brand-new strategy for time-critical vein thrombolytic therapy through efficient thrombolysis and multimodal imaging diagnosis.

Abstract
Peptides exhibit lower affinity and a shorter half-life in the body than antibodies. Conversely, peptides demonstrate higher efficiency in tissue penetration and cell internalization than antibodies. Regardless of the pros and cons of peptides, they have been used as tumor-homing ligands for delivering carriers (such as nanoparticles, extracellular vesicles, and cells) and cargoes (such as cytotoxic peptides and radioisotopes) to tumors. Additionally, tumor-homing peptides have been conjugated with cargoes such as small-molecule or chemotherapeutic drugs via linkers to synthesize peptide-drug conjugates. In addition, peptides selectively bind to cell surface receptors and proteins, such as immune checkpoints, receptor kinases, and hormone receptors, subsequently blocking their biological activity or serving as hormone analogs. Furthermore, peptides internalized into cells bind to intracellular proteins and interfere with protein-protein interactions. Thus, peptides demonstrate great application potential as multifunctional players in cancer therapy.

Bioeng Transl Med 2023; 8:e10405.

Abstract
Ionic liquids (ILs) attract more and more interests in improving drug transport across membrane, including transdermal, nasal, and oral delivery. However, some drawbacks of ILs impede the application in oral drug delivery, such as rapid precipitation of poorly soluble drugs in stomach. This study aimed to employ enteric mesoporous silica nanoparticles (MSNs) to load ILs to overcome the shortcomings faced in oral administration. The choline sorbate ILs (SCILs) were synthesized by choline bicarbonate and sorbic acid and then adsorbed in mesopores of MSNs after dissolving cyclosporin A (CyA). MSNs loading SCILs and CyA were coated by Eudragit® L100 to form enteric nanoparticles. The in vitro release study showed that the CyA and SCILs released only 10% for 2 h in simulated gastric fluids but more than 90% in simulated intestinal fluid. In addition, SCILs and CyA were able to release from MSNs synchronously. After oral administration, enteric MSNs loading SCILs were capable of improving oral absorption of CyA significantly and the oral bioavailability of CyA was similar with that of oral Neoral®. In addition, the oral absorption of enteric MSNs was higher than that of nonenteric MSNs, which showed that enteric coating was necessary to ILs in oral delivery. These findings revealed great potential of translation of ILs to be enteric nanoparticles for facilitating oral absorption of CyA. It is predictable this delivery system is promising to be a platform for delivering poorly water-soluble drugs and even biologics orally.

Abstract
Introduction Smart theranostic nanosystems own a favorable potential to improve internalization within tumor while avoiding nonspecific interaction with normal tissues. However, development of this type of theranostic nanosystems is still a challenge. Methods In this study, we developed the iodine-131 (131I)-labeled multifunctional polyethylenimine (PEI)/doxorubicin (DOX) complexes with pH-controlled cellular uptake property for enhanced single-photon emission computed tomography (SPECT) imaging and chemo/radiotherapy of tumors. Alkoxyphenyl acylsulfonamide (APAS), a typical functional group that could achieve improved cellular uptake of its modified nanoparticles, was utilized to conjugate onto the functional PEI pre-modified with polyethylene glycol (PEG) with terminal groups of monomethyl ether and N-hydroxysuccinimide (mPEG-NHS), PEG with terminal groups of maleimide and succinimidyl valerate (MAL-PEG-SVA) through sulfydryl of APAS and MAL moiety of MAL-PEG-SVA. This was followed by conjugation with 3-(4’-hydroxyphenyl)propionic acid-OSu (HPAO), acetylating leftover amines of PEI, complexing DOX and labeling 131I to generate the theranostic nanosystems. Results The synthesized theranostic nanosystems exhibit favorable water solubility and stability. Every functional PEI can complex approximately 12.4 DOX, which could sustainably release of DOX following a pH-dependent manner. Remarkably, due to the surface modification of APAS, the constructed theranostic nanosystems own the capacity to achieve pH-responsive charge conversion and further lead to improved cellular uptake in cancer cells under slightly acidic condition. Above all, based on the coexistence of DOX and radioactive 131I in the single nanosystem, the synthesized nanohybrid system could afford enhanced SPECT imaging and chemo/radioactive combination therapy of cancer cells in vitro and xenografted tumor model in vivo. Discussion The developed smart nanohybrid system provides a novel strategy to improve the tumor theranostic efficiency and may be applied for different types of cancer.

Abstract
Novel theranostic nanosystems demonstrate great potential to achieve timely diagnosis and effective therapy at the same time. However, due to the relatively low accumulation of theranostic nanosystems at the tumor site, the theranostic efficiency is limited. In this study, a novel theranostic nanosystem with a pH-responsive charge conversion property was constructed to improve the cellular uptake towards cancer cells for enhanced single photon emission computed tomography (SPECT)/computed tomography (CT) dual mode imaging and radiotherapy of tumors. In detail, polyethylenimine (PEI) was utilized as a nanoplatform to link with polyethylene glycol (PEG) monomethyl ether with one end of N-hydroxylsuccinimide (mPEG-NHS), PEG with ends of maleimide and succinimidyl valerate (MAL-PEG-SVA), alkoxyphenyl acylsulfonamide (APAS), 3-(4'-hydroxyphenyl)propionic acid-OSu (HPAO), and fluorescein isothiocyanate (FI), successively. The formed functionalized PEI was then utilized to entrap gold nanoparticles, acetylate the remaining amines of PEI and label with radioactive iodine-131 (131I) to build theranostic nanosystems. The result demonstrated that the theranostic nanosystem has a 3.8 nm Au core and showed excellent colloidal stability. On account of the charge conversion property of APAS, the APAS linked PEI entrapped gold nanoparticles could switch from neutral to positive in a slightly acidic microenvironment, which induced improved cellular uptake. Above all, after 131I labeling, the generated theranostic nanosystem could achieve enhanced SPECT/CT dual mode imaging and radiotherapy of cancer cells in vitro and a xenograft tumor model in vivo. The constructed APAS-linked PEI nanosystem has great potential to be used as a model for SPECT/CT imaging and radiotherapy of various types of cancer.

Abstract
Gadolinium-doped nanoparticles (NPs) are regarded as promising luminescent probes. In this report, we studied details of toxicity mechanism of low doses of NaGdF4-based fluorescent nanoparticles in activated RAW264.7, J774A.1 macrophages. These cell lines were specifically sensitive to the treatment with nanoparticles. Using nanoparticles of three different sizes, but with a uniform zeta potential (about −11 mV), we observed rapid uptake of NPs by the cells, resulting in the increased lysosomal compartment and subsequent superoxide induction along with a decrease in mitochondrial potential, indicating the impairment of mitochondrial homeostasis. At the molecular level, this led to upregulation of proapoptotic Bax and downregulation of anti-apoptotic Bcl-2, which triggered the apoptosis with phosphatidylserine externalization, caspase-3 activation and DNA fragmentation. We provide a time frame of the toxicity process by presenting data from different time points. These effects were present regardless of the size of nanoparticles. Moreover, despite the stability of NaGdF4 nanoparticles at low pH, we identified cell acidification as an essential prerequisite of cytotoxic reaction using acidification inhibitors (NH4Cl or Bafilomycin A1). Therefore, approaching the evaluation of the biocompatibility of such materials, one should keep in mind that toxicity could be revealed only in specific cells. On the other hand, designing gadolinium-doped NPs with increased resistance to harsh conditions of activated macrophage phagolysosomes should prevent NP decomposition, concurrent gadolinium release, and thus the elimination of its toxicity.

Abstract
Thrombosis, a critical event in blood vessels, not only is associated with myocardial infarction and stroke, but also accounts for considerable morbidity and mortality. Thrombolytic drugs are usually applied to the treatment of acute myocardial infarction, acute cerebral infarction and pulmonary embolism. However, thrombolytic drugs show limited efficacy in clinical practice because of the short half-life in plasma and systemic side effects. In this study, the cyclic RGD (cRGD) functionalized liposomes were prepared to encapsulate urokinase, a cheap and widely used thrombolytic drug in clinic and better thrombolysis efficacy was achieved. The flow cytometry analysis showed that the cRGD liposomes could bind to the activated platelets while not to the resting platelets. In vitro release study revealed that the release percentage reached plateau in about 5 h with 60% urokinase being released from liposomes. Results from the in vitro thrombolysis experiments demonstrated a good thrombolysis potential of the cRGD urokinase liposomes. The in vivo thrombolysis study demonstrated that the cRGD liposomes could significantly reduce the dose of urokinase by 75% while achieving the equivalent thrombolysis effect as the free urokinase in mouse mesenteric thrombosis model. In conclusion, the cRGD liposomes encapsulating urokinase hold great promise in clinic for better thrombolytic efficacy. STATEMENT OF SIGNIFICANCE In this paper, the cRGD liposomes were prepared to encapsulate urokinase for targeted thrombolysis therapy. The cRGD liposomes could specifically bind to the activated platelets and could stably and continuously release its loaded urokinase. The mouse mesenteric thrombosis model was established to evaluate the thrombolysis effect of the cRGD urokinase liposomes. The results demonstrated that the cRGD liposomes could improve the thrombolytic efficacy by almost 4-fold over free urokinase. In conclusion, the cRGD liposomes encapsulating urokinase had great potential for the clinical treatment of thrombosis.

Abstract
Integration of nanotechnology and biomedicine has offered great opportunities for the development of nanoscaled therapeutic platforms. Amongst various nanocarriers, mesoporous silica nanoparticles (MSNs) is one of the most developed and promising inorganic materials-based drug delivery system for clinical translations due to their simple composition and nanoporous structure. MSNs possess unique structural features, for example, well-defined morphology, large surface areas, uniform size, controllable structure, flexible pore volume, tunable pore sizes, extraordinarily high loading efficiency, and excellent biocompatibility. Progress in structure control and functionalization may endow MSNs with functionalities that enable medical applications of these integrated nanoparticles such as molecularly targeted drug delivery, multicomponent synergistic therapy, in vivo imaging and therapeutic capability, on-demand/stimuli-responsive drug release, etc. In this chapter, the authors overview MSNs' characteristics and the scientific efforts developed till date involving drug delivery and biomedical applications.

Abstract
Temperature-dependent zeolite synthesis has revealed a unique surface morphology, surface area and pore size which influence the immobilization of urease on gold electrode supports for biosensor fabrication. XRD characterization has identified zeolite X (Na) at all crystallization temperatures tested. However, N2 adsorption and desorption results showed a pore size and pore volume of zeolite X (Na) 60 °C, zeolite X (Na) 70 °C and zeolite X (Na) 90 °C to range from 1.92 nm to 2.45 nm and 0.012 cm3/g to 0.061 cm3/g, respectively, with no significant differences. The specific surface area of zeolite X (Na) at 60, 70 and 90 °C was 64 m2/g, 67 m2/g and 113 m2/g, respectively. The pore size, specific surface area and pore volumes of zeolite X (Na) 80 °C and zeolite X (Na) 100 °C were dramatically increased to 4.21 nm, 295 m2/g, 0.762 cm3/g and 4.92 nm, 389 m2/g, 0.837 cm3/g, in that order. The analytical performance of adsorbed urease on zeolite X (Na) surface was also investigated using cyclic voltammetry measurements, and the results showed distinct cathodic and anodic peaks by zeolite X (Na) 80 °C and zeolite X (Na) 100 °C. These zeolites’ molar conductance was measured as a function of urea concentration and gave an average polynomial regression fit of 0.948. The findings in this study suggest that certain physicochemical properties, such as crystallization temperature and pH, are critical parameters for improving the morphological properties of zeolites synthesized from natural sources for various biomedical applications.
