Nanoscale biophysics is the study of the physical principles governing biological processes occurring on a nanometre scale, typically on an atomic or molecular level. It also encompasses the development of nanotechnologies designed specifically for biophysical investigations.
Temporal blockade of the mononuclear phagocyte system is an approach to enhance the therapeutic efficiency of nanocarrier drug-delivery systems but the broad applicability is hindered by the complexity of optimisation and management of potential side effects. Here, the authors review the development of this technique and show its efficiency using meta-analysis of the published data and discuss essential features for its successful translation to clinic.
NCOMMS-23-44446C Vivid structural colours in butterflies are caused by photonic nanostructures scattering light, however insight into the development of such structures in vivo remains scarce. Here the authors show that actin plays a vital and direct templating role during structural colour formation in butterfly scales, providing ridge patterning mechanisms that are likely universal across lepidoptera.
A DNA-based nanorobotic arm connected to a base plate through a flexible joint can be used to store and release mechanical energy. The joint acts as a torsion spring that is wound up by rotating the arm using external electric fields and is released using a high-frequency electrical pulse.
Sequencing of proteins is a technically difficult task that typically requires digestion into short peptides before detection and identification. We developed a digestion-free method to chemically unfold and ‘scan’ full-length proteins through a nanopore, producing electrical fingerprints unique to individual protein molecules that are useful in their identification.
A paper in Nature Physics shows how the collective chiral motion of malaria single-cell organisms in mosquito saliva is driven by their physical properties
A paper in Science Advances shows how the transition of bacteria cells from collective active swarms to biofilms is driven by both biological and physical mechanisms.
