Bioplastics are derived from renewable carbon sources and/or are degradable at their end-of-life stage, thereby providing a potential solution to plastics pollution. However, lengthy and expensive testing and certification processes, as well as greenwashing and public misconceptions currently hinder the widespread usage and adequate disposal of bioplastics.

Nanoparticles can be systemically injected into the body for cancer diagnosis and treatment. Active transport mechanisms may enable nanoparticles to enter the tumour through active endothelial transport processes, retain in the tumour owing to interactions with tumour components, and exit the tumour through lymphatic vessels. See Luan N.M. Nguyen et al.

Single-cell RNA sequencing techniques and analysis methods can help improve our understanding of tissue injury responses and inform the design of new regenerative biomaterials and therapeutics. See Anna Ruta et al.

The motions of the heart are regulated by electrophysiological signals, which can be monitored and altered by bioelectronic devices for the diagnosis and treatment of cardiovascular diseases. In particular, soft bioelectronic devices, composed of deformable and conductive materials, can be implanted or designed as wearable devices to enable conformal contact with heart tissue or the skin for real-time and precise diagnosis and treatment.
