Sonodynamic therapy (SDT) represents a promising approach for cancer treatment. Compared to photodynamic therapy, SDT offers increased penetration depth and higher precision. However, the practical application of is constrained by low water solubility, poor tumor specificity, metabolic susceptibility most sonosensitizers. Recent research has explored use piezoelectric materials as sonosensitizers in treatment inhibition bacterial growth. Upon ultrasound excitation, separation electron-hole (e--h+) pairs occurs within material. By improving crystal structure material or incorporating other nanoparticles prevent rapid recombination e--h+ pairs, accumulates charges conduction band valence band, achieving redox potential O2/·O2 -. This enables serve sonosensitizer, leading concept termed Sono-Piezo Dynamic Therapy (SPDT). review aims define SPDT, provide systematic overview historical development SDT, elucidate mechanisms which act Importantly, various will be discussed terms their feasibility, advantages, disadvantages sonosensitizers, offering new perspectives identifying

Biophysical and clinical medical studies have confirmed that biological tissue lesions trauma are related to the damage of an intrinsic electret (i.e., endogenous electric field), such as wound healing, embryonic development, occurrence various diseases, immune regulation, regeneration, cancer metastasis. As exogenous electrical signals, conductivity, piezoelectricity, ferroelectricity, pyroelectricity, bioelectroactives can regulate field, thus controlling function cells promoting repair regeneration tissues. Materials, once polarized, harness their inherent polarized static fields generate field through direct stimulation or indirect interactions facilitated by physical friction, ultrasound, mechanical stimulation. The interaction with microenvironment allows for regulation compensation signals in damaged microenvironments, leading repair. technique shows great promise applications regeneration.

Chitosan (CHT) is a known piezoelectric biomacromolecule; however, its usage limited due to rapid degradation in an aqueous system. Herein, we prepared CHT film via solvent casting method and cross-linked alkaline solution. Sodium hydroxide facilitated deprotonation, leading increased intramolecular hydrogen bonding mechanical properties. The remained intact for 30 days environments. A systematic study revealed gradual increase the output voltage from 0.9 1.8 V under external force (1-16 N). In addition, showed remarkable antibacterial anti-inflammatory activities ultrasound stimulation inhibition of inflammatory cytokines. films also displayed enhanced cellular proliferation ∼5-fold faster migration NIH3T3 cells US stimulation.

Abstract Structural diversity of biomolecules leads to various supramolecular organizations and asymmetric architectures self‐assemblies with significant piezoelectric response. However, the piezoelectricity biomolecular has not been fully explored relationship between structures remains poorly understood, which hinders development biomaterials. Herein, for first time, vitamin‐based power generation is systematically explored. X‐ray diffraction studies revealed that vitamin molecules can self‐assemble into different structures, exhibited tunable coefficients ranging from 3.8 42.8 pC N −1 by density functional theory (DFT) calculations. Notably, B 7 D‐biotin (D‐BIO) superior due low crystal symmetry high polarization arrangements. The D‐BIO assemblies‐based nanogenerator (PENG) produced output voltages ≈0.8 V under a mechanical force 47 N, showing durability after 5400 pressing‐releasing cycles stability at least three months. PENG‐based wearable sensor successfully detected bending motions human limbs. Furthermore, insole converted biomechanical energy stable electrical upon foot movement, illuminating 12 light‐emitting diodes (LEDs). This work fills knowledge gaps in self‐assemblies, providing paradigms realizing high‐performance biomaterials through engineering.

Abstract Piezoelectric materials offer great promise due to their ability generate electric fields under mechanical stress, producing surface charges that drive otherwise kinetically sluggish redox reactions. The strained surfaces of these provide a unique advantage in controlling product selectivity and enabling reaction pathways are unattainable with conventional methods. This perspective highlights advancements, challenges, the future potential piezoelectric synthetic organic chemistry, focus on designing optimized for piezocatalyzed synthesis. Piezocatalysis is industrially relevant because its operational simplicity, mild, gram scale synthesis reusable catalysts, minimal solvent use, air tolerant conditions. It involves cycles facilitate one electron events without requiring light exposure or electrical bias. Despite significant progress, many fundamental aspects yet be fully understood. One example correlation between piezoelectricity catalytic activity, which not always linear, as demonstrated by comparison tetragonal cubic BaTiO₃. While BaTiO₃ piezoelectric, it shows excellent activity certain reactions such arylation, dicarbonylation, cyclization mechanochemical conditions comparable Considering all aspects, this aims stimulate discussion advance promising field right direction.

Abstract Periodontitis is an increasingly prevalent oral inflammatory disease, whose treatment faces potent challenges because of recurrent bacterial infections, excessive reactive oxygen species (ROS) production, as well unrelenting inflammation‐induced alveolar bone resorption during the pathological process. Herein, we present rational design and construction a multifunctional hydrogel platform composed quaternized chitosan/oxidized dextran (QCS/OD) component with high bactericidal activity immunomodulatory carbonized polymer dots from resveratrol (RSV‐CPDs) for periodontitis treatment. Such RSV‐CPDs@QCS/OD (RCQD) hydrogels exhibit characteristics including shape adaptability, self‐healing properties, pH‐responsibility, enabling it to adapt irregularly shaped periodontal tissues, degrade gradually in mildly acidic microenvironment periodontitis, release RSV‐CPDs controlled manner. Significantly, RCQD can effectively suppress proliferation bacteria alleviate oxidative stress, relieve inflammation via activating Nrf2/NF‐κB signaling pathway, ultimately fostering favorable environment regeneration both soft hard tissue. Overall, this study highlights great potential treating by addressing practical needs tissue regeneration.
