Combining the precision of CRISPR’s DNA searching ability with the speed and scalability of electronics, we have developed an ‘electronic DNA search engine’, called a CRISPR–Chip, which not only enables DNA detection without amplification, but also showcases the untapped potential of merging molecular biology with nanomaterial electronics. Here, we discuss highlights and challenges on the journey from the initial idea to the commercialization of the CRISPR–Chip.

The current drug development pipeline is time-consuming, costly and inefficient. To better model interactions between pharmaceuticals and human physiology and, thus, increase the likelihood of drug success in clinical trials, the effect of pharmacokinetic drug profiles on cellular behaviour should be tested early in drug development.

An article in Nature Communications reports the development of cultured meat with organoleptic properties by regulating the differentiation of stem cells to produce muscle and fat blocks.

An article in Nature Communications reports a battery-free, self-powered pacemaker for long-time treatment of arrhythmia.

An article in Nature Biotechnology reports flexible kirigami-based electronics that allow the non-invasive and long-term recording of electrical activity in neural organoids.

The mechanisms of nanoparticle delivery to solid tumours guide the engineering of nanoparticles for cancer applications. This Review discusses two contrasting nanoparticle delivery mechanisms, the enhanced permeability and retention effect and the active transport and retention principle, and their implications for the design of cancer nanomedicines.

Controlling blood circulation, biodistribution and tissue accessibility of nanomedicines is key to their clinical translation. In this Review, bioengineering strategies to overcome gatekeeping barriers and promote the targeting, safety and efficacy of nanomedicines are discussed.

Metabolic engineering allows the design of microorganisms for the bioproduction of specific metabolites, such as value-added chemicals. This Review discusses autonomous dynamic regulation approaches, including metabolite-specific transcriptional regulation and non-specific systems using environmental factors, quorum sensing and growth-phase regulation.

Vaccination and immune-regulation strategies are crucial for the prevention and treatment of respiratory infectious diseases. This Review discusses the design and optimization of nanomedicines for vaccines and immunotherapeutics for respiratory infectious diseases.

Fluid protein condensates are utilized as precursors in the production of high-performance biological fibres, adhesives and composites. This Review outlines the key role of condensates in the formation of several well-studied biological materials and highlights bioengineered materials with biomedical applications that draw inspiration from these archetypes.
