The adhesive, made from nanoparticles of hydroxyapatite, glues both synthetic hydrogels and mouse soft tissue, providing a promising alternative to organic materials currently in use for clinical applications.
Materials scientists and engineers are reporting success in developing a new material that promises to help ensure that microelectromechanical systems can continue to meet the demands of the next technological frontier.
Researchers designed 'two-faced' spherical particles to perform the task. One face is made with magnesium, which reacts with water to produce hydrogen bubbles to propel the microbots. The other face is made out of alternating iron and gold layers topped by silver nanoparticles.
Scientists are investigating how to tailor drug therapies using exosomes - nanoscale sacs full of biomarkers like lipids, proteins and nucleic acids found in bodily fluids - that can be used to achieve a noninvasive 'liquid biopsy'.
