“…54 Similarly, the large interparticle distance of 3D PCs is realized by the self-assembly of monodisperse nanoparticles into an ordered structure in the colloidal solution mixed with the polymer precursor, followed by polymerization to stabilize the nonclose packed structure. When excess a concentration threshold (e.g., 8% (vt)in the work of Huang et al 55 and 12 wt % reported by Hong et al 56 ), nanoparticles can spontaneously self-assemble into an ordered structure due to the repulsive interparticle interaction caused by a sufficient charge 57 and solvation layer 58 on the nanoparticle surface. Compared with the face-centered-cubic 3D close packed counterpart which provides 26% volume fraction of voids, 59 the nonclose packed colloidal PC template leaves a much larger space for the filling of soft materials.…”

The sensitivity of colorimetric photonic crystal (PC) sensors have been significantly improved with the advancement of deformable structural color materials, structures design, sensing signal analysis methods, and fabrication strategies. In this perspective, the strategies toward high-sensitivity colorimetric PC sensors are discussed, from the perspectives of molecular design, single sensor construction, and multisensor assembly, which include incorporation of flexible polymer chains, construction of strong sensor−analyte interactions, incorporation of more soft materials, construction of stimuli-angle/orientation relationship, design of colorimetric sensors in series, and assembly of colorimetric PC sensors in parallel. Based on these strategies, progress of high-sensitivity colorimetric PC sensors in recent years is summarized, in terms of mechano-sensors and chemo-/biosensors. Specifically, PC based optical-electrical dual-signal sensing devices are included. Finally, the future development and challenges of high-sensitivity colorimetric PC sensors are presented, in regards to deformable properties, optical properties, analysis methods, and fabrication strategies.

“…recently 4D printed bilayer hydrogel‐based nonclose‐packed colloidal photonic crystals (NCPCs) (PNIPAm and PAAm NCPCs) via DLP. [ 75 ] As illustrated in Figure a‐i,ii, the PNIPAm‐based NCPCs shrank under heating due to the release of water. As the temperature increased, the 4D‐printed biomimetic flower gradually changed from the open state to the closed state accompanied by a blue‐shift of the structural color (Figure 6a‐iii).…”

Inspired by shape-morphing organisms in nature, researchers have developed various hydrogels with stimuli-responsive swelling, shrinking, bending, folding, origami, rolling, twisting, or locomotion. These smart hydrogels are usually created by patterning or 4D printing. The shape morphing of hydrogels allows the fabrication of helixing, twisting, and rolling microstructures, all of which are hard to reproduce directly by ordinary techniques. More importantly, under external stimuli (e.g., solvent, humidity, temperature, light, pH, and electric/magnetic fields), many hydrogels exhibit recoverable shape morphing and thus find promising applications in grippers, sensors, valves, soft robotics, etc. Since shape morphing determines the functions of hydrogels in a great number of cases, herein, recent advances of stimuli-responsive hydrogels are summarized, with their types, shape-morphing mechanisms, fabrication methods, shape-morphing modes, and extensive applications covered. The conclusion and perspectives are also presented to guide the design and fabrication of functional hydrogels.

Silk fibroin, regenerated from Bombyx mori, has shown considerable promise as a printable, aqueous-based ink using a bioinspired salt-bath system in our previous work. Here, we further developed and characterized silk fibroin inks that exhibit concentration-dependent fluorescence spectra at the molecular level. These insights supported extrusion-based 3D printing using concentrated silk fibroin solutions as printing inks. 3D monolithic proteinaceous structures with high aspect ratios were successfully printed using these approaches, including cantilevers only supported at one end. This work provides further insight and broadens the utility of 3D printing with silk fibroin inks for the microfabrication of proteinaceous structures.
