Concurrent induction of ferroptosis and apoptosis by enzyme catalysis represents a promising modality for cancer therapy. Inspired the structures DNA G-quadruplex/hemin DNAzyme, DNA-free guanosine-based polymer nanoreactor (HPG@hemin-GOx) is prepared as ferroptosis-apoptosis inducer one-step assembly phenylboronic acid-modified hyaluronic acid (HA-PBA), guanosine (G), hemin, glucose oxidase (GOx). HPG@hemin-GOx shows GOx, peroxidase (POD)-like, catalase (CAT)-like, glutathione (GPX)-like activities. The GOx activity can increase intracellular hydrogen peroxide (H

Self-healing, stretchable, and moldable hydrogels have a great potential application in tissue engineering soft robotics. Despite success reported hydrogels, it is still challenge to construct the with an ultrafast self-healing performance. Herein, composite (PBLH) self-healing, properties were successfully constructed by poly (vinyl alcohol) (PVA), borate (B), ε-poly-l-lysine (EPL), hyaluronic acid (HA) based on efficient one-pot method. Fourier transform infrared spectroscopy, X-ray diffraction, rheological measurements confirmed formation of dynamic network among PVA, B, EPL, HA through cross-linking bonds, electrostatic interaction, hydrogen bonding. Having fabricated structure, damage gap can heal within 1 min, presenting excellent ability. Simultaneously, be molded into various shapes, length stretched 15 times their original length. In addition, exhibited antibacterial property against Staphylococcus aureus (S. aureus) Escherichia coli (E. coli). Our results illustrated that not only retain advantages traditional but also possess outstanding stretchable properties, prospective candidate for constructing biomedical materials.

Donor–acceptor (D-A) conjugated polymers have large Stokes shifts, high photostability, and good biocompatibility thus are ideal for use as Raman probes in vivo. However, few D–A used imaging due to their weak signal intensity intrinsic fluorescence interference. Here, we developed a polymer probe (CDT-TT) containing alternating cyclopentadithiophene-thienothiophene units of tumor sentinel lymph nodes (SLNs). The CDT-TT shows strong at 1389 cm–1 without lipid background interference under 785 nm near-infrared light. Moreover, the loaded nanoparticles realized accurate cells tissues. In addition, high-resolution margin situ SLNs was acquired. Taken together, established method is effective detection tumors SLNs, which may shed new light on development clinical imaging.
