Carbon nanotubes, with their unique properties, could make electrical conductors of unprecedented performance, which could revolutionize energy transport globally. Is it feasible to produce macroscopic conductors from nanoscale structures? This Feature Article presents both the most recent results of a highly promising research program in this area and the key challenges that need to be overcome.

A novel application range of graphene hydrogel in wound dressing is exploited. The hydrogels are composed of Ag–graphene composite, AA, and BIS. When the mass ratio of Ag to graphene is 5:1, the hydrogel (Ag5G1) shows strong antibacterial activity, large swelling ratio, excellent biocompatibility, and good extensibility, and it can significantly accelerate the healing rate of artificial wounds in rats.

A novel amorphous-indium-gallium-zinc-oxide-based application with stable switching characteristics under negative bias illumination is shown. Metallic nanohole-based plasmonic filters are used for tuning the spectrum of the ambient light source, and the photosensitivity of the a-IGZO-TFT is investigated within a selectively controlled spectral range. The suggested thin-film transistors show greatly improved stability even in a negative bias illumination stress environment.
- Vapor Phase Metal-Assisted Chemical Etching of Silicon

To overcome non-uniformity and microporous silicon generation seen in traditional liquid-phase metal-assisted chemical etching, vapor-phase metal-assisted chemical etching (VP-MaCE) is used instead. The etch rate is evaluated as a function of catalyst, time, and substrate temperature.
- Polylactide-block-Polypeptide-block-Polylactide Copolymer Nanoparticles with Tunable Cleavage and Controlled Drug Release

Triblock copolymer nanoparticle with tunable drug release. Nanocarriers based on PLLA-b-peptide-b-PLLA copolymers prove to have exceptional material properties for controlled drug release in response to MMP-2-dependent peptide cleavage. Comparison specimens demonstrate the tunable bioactivity of these nanocarriers based on polymer constitution. As MMP-2 is selectively overexpressed in tumor tissues, this is a promising system for solid tumor cancer therapy.
