Summary: Developing protective materials with intelligent and stimuli-responsive properties is essential for safety purposes. However, combining contradictory properties into a single polymer is challenging. In this study, a strain-hardening supramolecular polyurethane nanocomposite (SPN) with high mechanical strength and unique impact protection properties is synthesized by incorporating quadruple hydrogen bonds (H-bonds), disulfide bonds, and modified silica nanoparticles into polyurethane elastomer. This SPN material exhibits high energy absorption efficiency and impact protection properties through the dynamic break and re-form characteristic of quadruple H-bonds and the stress dissipation behavior of nanoparticles.

Summary: Starch with active hydroxyl groups has become a popular choice for gel preparation in recent years. However, current starch-based gels often have unsatisfactory mechanical properties, self-healing properties, self-adhesion properties, and low-temperature resistance. In this study, a multiple network structure of amylopectin-carboxymethyl cellulose-polyacrylamide (ACP) gel was prepared, and tannic acid (TA) was used to enhance its performance. The ACP gel demonstrated high elongation at break, strength, self-healing performance, self-adhesion behavior, extraordinary low-temperature resistance, and self-extinguishing ability. It also showed potential in various applications such as sensor devices and temperature monitoring.

Summary: In this study, a successful construction of zwitterionic copolymers (poly (sulfobetaine methacrylate-co-butyl acrylate) (pSB) coating on the surface of a hydroxylated titanium sheet using surface-initiated atom transfer radical polymerization (SI-ATRP) was achieved. The successful preparation of the coating was confirmed by X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FT-IR), and water contact angle (WCA) analysis. The swelling effect caused by the antipolyelectrolyte effect was observed in vitro, and the coating promoted the proliferation and osteogenesis of MC3T3-E1. Therefore, this study provides a new strategy for designing multifunctional biomaterials for implant surface modifications.

Summary: Utilizing an umpolung strategy, a rare electrochemical cross-coupling reaction between electron-deficient methylarenes and aldehydes was achieved. By paired electrolysis, electron-deficient benzylic radicals and ketyl radicals were generated and then underwent radical recombination governed by polarity matching and persistent-radical effect (PRE), resulting in functionalized alcohols that are difficult to obtain with other methods. This protocol offers catalyst and external redox agent-free conditions and a formal 100% atom economy. Mechanistic studies support the radical-radical cross-coupling pathway.

Summary: CRISPR/Cas9 is a powerful tool for gene editing, but it is challenging to screen modified cells. This study developed two novel traffic light screening reporters, PMG-SSA and PMG-HDR, to measure nuclease activity and select genetically modified cells. The reporters can be self-repaired, resulting in a functional selection cassette that can be used for screening. The results showed improved enrichment efficiencies for gene knockout and knock-in cells. These surrogate reporters advance CRISPR/Cas9-mediated editing in mammalian cells.
