In an aspect, provided herein are low density materials, including shell-based materials, with three-dimensional architectures formed, in part, via self-assembly processes. Shell-based materials of some embodiments exhibit a combination of ultralow density (e.g., ≤100 mg cmand optionally ≤10 100 mg cm) and non-periodic architectures characterized by low defect densities and geometries avoiding stress concentrations. Low density shell based materials of some embodiments have architectures characterized by small curvatures and lack of straight edges providing enhance mechanical response. In some embodiments, for example, the present low density materials, including shell-based materials, providing a combination target mechanical properties including high stiffness-to-density ratios, mechanical resilience and tolerance for deformation.

Self-assembly of shell-based architected materials

In an aspect, a method for making a metal-containing material comprises steps of: forming a metal-containing hydrogel from an aqueous precursor mixture using a photopolymerization; wherein the aqueous precursor mixture comprises water, one or more aqueous photosensitive binders, and one or more aqueous metal salts; and thermally treating the metal-containing hydrogel to form the metal-containing material; wherein the metal-containing hydrogel is exposed to a thermal-treatment atmosphere during the step of thermally treating; wherein a composition of the metal-containing material is at least partially determined by a composition of the thermal-treatment atmosphere during the thermally treating step.

3D printing of metal containing structures

This disclosure is directed to structured compositions, including DNA-functionalized scaffolds, for drug capture, and methods and devices for sequestering chemotherapeutics from physiological fluids using the functionalized scaffolds.
