With recent advancements in technology, the Internet of Things and wireless devices are in high demand. However, these innovations also raise concerns about prolonged exposure to electromagnetic radiation (EMR), which may pose potential risks to eye health.
MXenes, a class of two-dimensional transition metal carbides/nitrides, have shown promise in shielding against EMR. However, their poor adhesion and susceptibility to oxidation have limited their applications.
In a recent breakthrough, researchers led by Professor Takeo Miyake from the Graduate School of Information Production and Systems, Waseda University, Japan, have developed stable MXene-coated contact lenses with remarkable optical and EMR shielding properties.
Their novel fabrication method ensures optimum adhesion and prevents oxidation of the MXene coating, overcoming previous limitations.
The study was a collaborative effort between Waseda University, Kyoto University, and Yamaguchi University Hospital, bringing together expertise in nanofabrication, 2D materials, and ophthalmology to ensure eye safety.
The findings are published in the journal Small Science.
