XPANCEO, a deep tech firm creating the following era of computing by its first sensible contact lenses, in collaboration with Nobel laureate Konstantin S. Novoselov (College of Manchester, Nationwide College of Singapore), has developed an modern technique for producing biocompatible, clear, ultrathin gold movies with no space restriction. With superior electrical conductivity, these movies pave the best way for next-generation versatile and clear electrodes, with promising purposes in versatile shows, digital paper, prolonged actuality units, digital tattoo, implantable and wearable electronics.

Traditionally, producing clear steady and conductive gold movies thinner than 10 nm was thought-about unattainable as a consequence of steel island formation throughout deposition. Conventional chemical synthesis strategies, equivalent to these behind Goldene, additionally failed to provide massive, steady gold movies, limiting their areas to 0.000001 mm2. In distinction, XPANCEO’s graphene-inspired method, developed alongside Prof. Novoselov, overcomes these challenges by enabling movies as skinny as 3.5 nm utilizing a high-vacuum deposition system — an ordinary useful resource in analysis laboratories.
“Two-dimensional materials are no longer confined to theoretical research, they are now becoming part of real-world technology. This method allows the scalable production of gold films exceeding 1 m2, leveraging roll-to-roll transfer techniques similar to those used in graphene manufacturing, which have been refined over the past 15 years. Compatible with current microelectronics processes, it allows for efficient, cost-effective production. Now, two-dimensional gold technology will be accessible in any research laboratory, unlocking new possibilities in electronics,” says Professor Sir Konstantin Novoselov, Nobel Laureate for the invention of graphene’s distinctive properties.
One other benefit is that the movies may be transferred to just about any substrate, from organic tissues to microchips. The switch course of, just like making use of a sticker, is environment friendly and adaptable, enabling placement on delicate surfaces with excessive precision. Their atomic-scale thickness, biocompatibility and chemical stability surpass conventional clear conductors like indium tin oxide, making them appropriate for mind and coronary heart implants, neural interfaces, and wearable medical sensors, considerably decreasing the dangers of scarring and hostile reactions. Consequently, they are perfect for use in superior medical applied sciences, together with neural implants like Neuralink’s mind chips.
“This breakthrough has potential applications in flexible optoelectronics, including foldable displays, e-paper, and wearable tech, transforming consumer devices like smartphones, tablets, and TVs, while also paving the way for entirely new categories of technology, such as smart contact lenses. In our lab, we’re already working with transparent gold films just 0.5 nm thick—equivalent to a few atomic layers—which holds promise for both cutting-edge technologies and fundamental physics research, ” says Dr. Valentyn Volkov, co-founder and CTO of XPANCEO, an internationally famend knowledgeable within the discipline of nanophotonics and superior supplies.
The distinctive electrical conductivity and transparency of those movies are key to advancing sensible contact lens expertise with XR imaginative and prescient, well being monitoring and content-surfing options. The incorporation of those ultrathin movies is important, as they permit the required digital elements to be embedded seamlessly into the lens construction, sustaining the thinness of present medical lenses whereas enhancing each performance and luxury.
