Abstract Herein, a borophene/zinc oxide (BZ) nanocomposite is synthesized through straightforward one‐step solvothermal process, avoiding the need for any rigorous reducing agent. The BZ nanocomposites are introduced into semi‐interpenetrating polymer networks to form hydrogels via in situ UV triggered free radical gelation during three‐dimensional (3D) microextrusion printing. exhibit mechanical robustness, high compressibility, pH sensitivity, and microporosity. diffusion behavior of hydrogel shows combination swelling molecular chain relaxation based on its water uptake kinetics. Hydrogels tested environments over multiple cycles ensure structural integrity. rheological assessment proves their elasticity. uniaxial properties support toughness zero permanent set resulting elastomeric soft matrix. cyclic compression test up 100 has negligible data deviations calculating moduli (≈24 kPa). non‐toxic found be effective bactericidal materials both Gram‐positive Gram‐negative bacteria. demonstrates pH‐responsive time‐dependent payload release behavior, suggesting potential as matrix drug carrier biomedical research. To best authors knowledge, this first report BZ‐based biomaterial with antibacterial serving an excellent controlled delivery device.

Abstract Flexible sensors based on MXene-polymer composites are highly prospective for next-generation wearable electronics used in human–machine interfaces. One of the motivating factors behind progress flexible is steady arrival new conductive materials. MXenes, a family 2D nanomaterials, have been drawing attention since last decade due to their high electronic conductivity, processability, mechanical robustness and chemical tunability. In this review, we encompass fabrication MXene-based polymeric nanocomposites, structure–property relationship, applications sensor domain. Moreover, our discussion not only limited design, mechanism, various modes sensing platform, but also future perspective market throughout world. With article, intend fortify bond between matrices MXenes thus promoting swift advancement MXene-sensors technologies.

Hydrogels have a significant impact on the fields of biological study and medical diagnosis. They are becoming more useful in bioanalytical biosensing applications. The intriguing new nanomaterials quantum dots-hydrogel composites gained lot interest because their unmatched biocompatibility tolerable biodegradability, which opens up wide range possible Focusing synthesis techniques, this review describes current developments composites, such as hydrogel gelation dots (QDs) solution, inserting prepared QDs into hydrogels after gelation, generating situ inside preformed gel, cross-linking through QDs. Biomedical applications bioimaging specifically examined, then inherent problems design optimisation, biocompatibility, bimodal applications, well potential future development, discussed.

Superparamagnetic nanoparticle-arrested hydrogel matrices have immense significance in smart soft biomaterials. Herein, we report the synthesis of superparamagnetic nanoparticle-loaded magneto-responsive tough elastomeric hydrogels for dual-responsive drug delivery. In first phase work, carried out room-temperature amine-functionalized iron oxide nanoparticles (IONPs), and second demonstrated that IONPs could act as a toughening agent well viscosity modifier poly(acrylic acid-co-hydroxyethyl methacrylate) copolymer hydrogels. The was tested by Fourier transformed infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), continuous-wave-electron paramagnetic resonance (CW-EPR). Moreover, affect its gelation time elasticity significantly, which also evaluated from rheological behavior. compressive mechanical strength (∼120 kPa), elasticity, recovery to original shape (zero permanent set), water uptake, thixotropic behavior under dynamic stress hybrid supported robustness swelled state. release showed dual parameter dependency (IONPs cross-linker) responsiveness against both pH static magnetic field. delayed network rupturing, delivery nature, noncytotoxic human live cells promote this an ideal alternative remotely controlled vehicle.

Abstract Cephalopods use stretchy skin and dynamic color‐tuning organs for visual communication camouflage. Inspired by these natural mechanisms, a fluorescent biomaterial deformation‐induced illumination optical is proposed. This the first report of 3D printed soft biomaterials infused with carbon dots hydrothermally derived from chitosan benzalkonium chloride. These exhibit comprehensive array properties, including significant uniaxial stretching, near‐instantaneous response to tactile stimuli pH, UV resistance, antibacterial, antioxidant, noncytotoxicity, highlighting their potential as mechano‐optical materials biomedical applications. The hydrogel's durability evaluated cyclic folding, rolling, twisting tests ensure its integrity good signal‐to‐noise ratio. diffusion mechanism determined water imbibition kinetics, network parameters, time‐dependent breathing. Overcoming common limitations short lifespans complex manufacturing processes in existing hybrids, this work demonstrates straightforward method produce durable, energy‐independent, hydrogel. Combined investigations, molecular modeling used understand interactions hydrogel components.
