Abstract Tumor immunotherapy exerts its anti-tumor effects by stimulating and enhancing immune responses of the body. It has become another important modality therapy with significant clinical efficacy advantages compared to chemotherapy, radiotherapy targeted therapy. Although various kinds tumor immunotherapeutic drugs have emerged, challenges faced in delivery these drugs, such as poor permeability low cell uptake rate, had prevented their widespread application. Recently, nanomaterials emerged a means for treatment different diseases due targeting properties, biocompatibility functionalities. Moreover, possess characteristics that overcome defects traditional immunotherapy, large drug loading capacity, precise easy modification, thus leading wide application immunotherapy. There are two main classes novel nanoparticles mentioned this review: organic (polymeric nanomaterials, liposomes lipid nanoparticles) inorganic (non-metallic metallic nanomaterials). Besides, fabrication method nanoparticles, Nanoemulsions, was also introduced. In summary, review article mainly discussed research progress based on past few years offers theoretical basis exploring strategies future.

Abstract Architected hydrogels are widely used in biomedicine, soft robots, and flexible electronics while still possess big challenges strong toughness, shape modeling. Here, inspired with the universal hydrogen bonding interactions biological systems, a strain‐induced microphase separation path toward achieving printable, tough supramolecular polymer by bond engineering is developed. Specifically, it subtly designs fabricates poly (N‐acryloylsemicarbazide‐co‐acrylic acid) high energy phase conversion induced reconstruction. The resultant exhibited unique behavior, resulting excellent toughness with, for example, an ultimate stress of 9.1 ± 0.3 MPa, strain levels 1020 126%, 33.7 6.6 MJ m −3 , fracture 171.1 34.3 kJ −2 . More importantly, engineered dynamic memory character, i.e fixing at low temperature recovery after heating. As proof concept, tailored hydrogel stents readily manufactured 3D printing, which showed good biocompatibility, load‐bearing drug elution, being beneficial biomedical applications.

Overexpression of classically activated macrophages (M1) subtypes and assessed reactive oxygen species (ROS) levels are often observed in patients with ulcerative colitis. At present, the treatment system these two problems has yet to be established. Here, chemotherapy drug curcumin (CCM) is decorated Prussian blue analogs a straightforward cost-saving manner. Modified CCM can released inflammatory tissue (acidic environment), eventually causing M1 transform into M2 inhibiting pro-inflammatory factors. Co(III) Fe(II) have abundant valence variations, lower REDOX potential CCM-CoFe PBA enables ROS clearance through multi-nanomase activity. In addition, effectively alleviated symptoms UC mice induced by DSS inhibited progression disease. Therefore, present material may used as new therapeutic agent for UC.

Oral administration is a widespread and convenient drug delivery approach. However, oral can be affected by the complex digestive tract environment, including irregular tissue morphology, presence of enzymes, mucus mucosal barriers, spatiotemporal variance in physiological parameters. These obstacles prevent many therapeutics. To overcome these challenges, devices designed with bioinspired compositions, structures or functions to make more drugs available for administration. Various have been developed harnessing biological materials living microorganisms, imitating functions. In this Review, we discuss design modification devices, examining engineering strategies target specific tissues applications. We highlight how key bottlenecks addressed through designs, concluding an outlook on remaining challenges towards clinical translation devices. commonly used strategy deliver harsh environment prevents negatively affect efficacy. This Review discusses microorganisms into that associated delivery.

Pills are a cornerstone of medicine but can be challenging to swallow. While liquid formulations easier ingest, they lack the capacity localize therapeutics with excipients nor act as controlled release devices. Here we describe drug based on in situ-forming tough (LIFT) hydrogels that bridge advantages solid and dosage forms. LIFT form directly stomach through sequential ingestion crosslinker solution calcium dithiol crosslinkers, followed by drug-containing polymer alginate four-arm poly(ethylene glycol)-maleimide. We show robustly stomachs live rats pigs, mechanically tough, biocompatible safely cleared after 24 h. deliver total dose comparable unencapsulated manner, protect encapsulated therapeutic enzymes bacteria from gastric acid-mediated deactivation.
