Quick summary
- Researchers from Waseda University, Kyoto University, and Yamaguchi University Hospital have developed MXene-coated contact lenses with superior optical and electromagnetic radiation (EMR) shielding properties.
- MXenes are 2D transition metal carbides/nitrides known for EMR shielding. Innovations overcome their previous limitations such as poor adhesion and oxidation susceptibility.
- The fabrication method involves a wet-transfer approach using acetone to coat MXene films onto commercial soft contact lenses. This ensures high scalability,adhesion,and prevents oxidation.
- Key results: >80% visible light transmission, strong conductivity, dehydration protection, biocompatibility (>90% cell viability), and up to 93% shielding efficiency against high-frequency EMR.
- Tests on porcine eyes revealed effective absorption of electromagnetic energy when exposed to microwaves-protecting the eyes by dissipating heat energy rather than allowing direct heating.
- This innovation not only ensures eye health but opens avenues for integrating advanced nanomaterials in wearables, medical devices, implants, and bioelectronics.
