Bio-based plastics offer the advantage of biodegradability over traditional petroleum-based plastics, enabling natural reintegration into the environment and positioning them as a more sustainable alternative. DNA, as a natural biopolymer, exhibits excellent biocompatibility and degradability. However, the mechanical strength of currently biomass DNA-based materials is inferior to that of other bio-based and petroleum-based plastics. In this work, DNA plastics with a ″brick-and-mortar" structure were fabricated using DNA extracted from onions through bidirectional freezing, water vapor annealing, and compression densification. This biomimetic design significantly enhances the fracture toughness (∼1.5 MPa·m1/2) while possessing a high elastic modulus (∼560 MPa) of DNA plastic, making it superior or comparable to existing bio-based plastics and petroleum-based plastics, and thus positioning it as a potential structural material. Analysis of crack propagation behavior in DNA plastics reveals that their high toughness stems from a hierarchical ″brick-and-mortar″ structure operating across multiple length scales, facilitating a multiscale fracture process from macroscopic to molecular levels. Furthermore, these DNA plastics can be efficiently recycled in aqueous environments and fully biodegraded by enzymes, demonstrating strong environmental friendliness and significant potential for sustainable development. © 2025 The Authors.

Charge density wave (CDW) and their interplay with correlated and topological quantum states are at the forefront of condensed matter research. The 4Hb−TaS2 is a CDW ordered quantum heterostructure that is formed by alternative stacking of Mott insulating 1T-TaS2 and Ising superconducting 1H-TaS2. While the 13×13 and 3×3 CDWs have been respectively observed in the bulk 1T-TaS2 and 2H-TaS2, the CDWs and their pivotal role for unconventional superconductivity in the 4Hb−TaS2 remain unsolved. In this Letter, we reveal the two-dimensional (2D) 13×13 chiral CDW in the 1T layers and intraunit cell coupled 2D 2×2 CDW in the 1H and 1H' layers of 4Hb−TaS2. Our results establish 4Hb−TaS2 a 2.5D quantum heterostructure, where 2D quantum states emerge from 3D crystalline structure.
