In a study recently published in the journal ACS Nano, published by American Chemical Society, researchers from Kanazawa University, Kanazawa, Japan, collaborating with University of Washington, Seattle, USA, used frequency modulated atomic force microscopy to reveal the molecular architecture of a genetically designed peptide and its self-organization that forms single-molecule thick crystals on atomically flat graphite surfaces, that offer a potential platform for hybrid technologies such as bioelectronics, biosensors, and protein arrays.

Researchers from The Institute of Scientific and Industrial Research (SANKEN) at Osaka University and collaborating partners prepared hierarchical hydrogels and moldings that consisted of anisotropic, ecofriendly cellulose nanofibers. By simply tailoring the applied voltage during fabrication, complex architectures—such as microneedles and multilayer hydrogels—were easy to prepare. The results of this work will reduce the need for petroleum-based plastics, and in so doing minimize a long-standing source of environmentally persistent waste.

Face masks have become an important tool in fighting against the COVID-19 pandemic. However, improper use or disposal of masks may lead to "secondary transmission". A research team from City University of Hong Kong (CityU) has successfully produced graphene masks with an anti-bacterial efficiency of 80%, which can be enhanced to almost 100% with exposure to sunlight for around 10 minutes. Initial tests also showed very promising results in the deactivation of two species of coronaviruses. The graphene masks are easily produced at low cost, and can help to resolve the problems of sourcing raw materials and disposing of non-biodegradable masks.
