Neuromodulation and brain–computer interfaces are rapidly evolving fields with distinct origins but with the shared goal of improving the lives of people with neurological and psychiatric disorders or injuries. Their increasing technological overlap provides new opportunities for collaborative work and rapid progress in neurotechnology.
Fats and oils are crucial dietary supplements for human health. However, animal fats and palm oil dominate the food industry, with concerns over health and the environment that call for the development of fat alternatives. The fat industry offers a vast market potential, with several startups pioneering new technical solutions and attracting venture capital interest.
Using nanoparticles featuring anisotropic characteristics is a promising approach to developing multifunctional platforms for drug delivery and theranostics. This Review discusses methods to generate anisotropy in nanosystems and strategies to control particle transport, targeting and interaction with cells to overcome biological barriers.
Bioplastics have yet to make an impact in addressing plastics pollution. Policy measures, innovation and public discourse are needed to address misconceptions, clarify labelling and ensure their effective end-of-life management.
An article in Communications Engineering reports a 3D real-time magnetic particle scanner suitable for brain imaging at the patient’s bedside in intensive care units.
Motion artefacts challenge the translational application of soft bioelectronics by distorting physiological monitoring. This Review introduces fundamental causes of motion artefacts and discusses various management strategies, including materials usage, bioelectronics design and algorithmic intervention.
The clinical translation of therapeutics on the basis of human gut microorganisms is hampered by our limited knowledge of how microbes survive and adapt to fluctuating conditions in the gut. The systematic exploration of gut microbiome survival strategies and trade-offs will thus enable the design of more efficient microbiome-based interventions.
Microfluidic 3D cell culture platforms may serve as tools for the modelling of human tissues. This Review discusses the design, standardization and automation of such systems for non-clinical drug evaluation and investigation of disease.
What does global health equity mean? In bioengineering, ‘equity’ is often interpreted as global ‘access’ to technologies, thereby neglecting wider structural inequalities. Here we suggest that concepts of equity need to be expanded to incorporate principles of equitable representation and recognition within the innovation ecosystem.
Ultrasound is an emerging tool for tissue engineering with the distinct advantages of cytocompatibility and deep tissue penetration. This Review discusses the integration of ultrasound for cellular assembly and tissue maturation with tissue-engineering techniques to advance regenerative medicine.
Hydrogels are being explored and clinically applied for a variety of biomedical and clinical applications. This Review outlines a model-based modular hydrogel design framework that is application-driven and considers clinical translation early in the design process, emphasizing the importance of fundamental modelling and standardized design.
The application of nanoscale drug delivery systems by subcutaneous (SC) administration may circumvent disadvantages of other injections routes, such as intramuscular and intravenous administration. This Review discusses the design and clinical translation of nanoscale drug delivery systems for SC administration for the treatment of various conditions.
Micro- and nanorobots present a promising approach for navigating within the body and eliminating biofilm infections. Their motion can be remotely controlled by external fields and tracked by clinical imaging. They can mechanically disrupt the biofilm matrix and kill the dormant bacterial cells synergistically, thereby improving the effectiveness of biofilm eradication.
A long-standing nanoparticle delivery paradigm in cancer, that is, the enhanced permeability and retention effect, has been challenged, shifting the focus to active delivery mechanisms, which may provide a new mechanistic foundation for nanoparticle design.
The cryopreservation of biological samples is hindered by ice formation and the need to maintain samples under cryogenic conditions during storage and transportation. Silicification offers a simple method for preserving life within refractory, amorphous silicon dioxide, which is analogous to vitreous ice but does not melt and thereby avoids cold-chain issues.
Small-scale wireless soft robotic devices are promising tools for various medical applications. This Review outlines safety, navigation and functionality challenges, as well as the ethical and regulatory considerations that remain to be addressed for their clinical translation.
The Navion, a clinical-scale electromagnetic navigation system, is the result of over 20 years of development. Its motivation began in 2003 with the goal of controlling the motion of magnetic microrobots; however, its first clinical use is proving to be for guiding magnetic catheters, guidewires and endoscopes.
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.
