XPANCEO, a deep tech firm creating the subsequent technology of computing by way of its first good contact lenses, in collaboration with Nobel laureate Konstantin S. Novoselov (College of Manchester, Nationwide College of Singapore), has developed an progressive technique for producing biocompatible, clear, ultrathin gold movies with no space restriction. With superior electrical conductivity, these movies pave the way in which 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 of inconceivable as a consequence of steel island formation throughout deposition. Conventional chemical synthesis strategies, resembling these behind Goldene, additionally failed to supply giant, steady gold movies, limiting their areas to 0.000001 mm2. In distinction, XPANCEO’s graphene-inspired strategy, developed alongside Prof. Novoselov, overcomes these challenges by enabling movies as skinny as 3.5 nm utilizing a high-vacuum deposition system — a normal useful resource in analysis laboratories.
“Two-dimensional supplies are not confined to theoretical analysis, they’re now changing into a part of real-world expertise. This technique permits the scalable manufacturing of gold movies exceeding 1 m2, leveraging roll-to-roll switch methods much like these utilized in graphene manufacturing, which have been refined over the previous 15 years. Suitable with present microelectronics processes, it permits for environment friendly, cost-effective manufacturing. Now, two-dimensional gold expertise will probably be accessible in any analysis laboratory, unlocking new potentialities in electronics,” says Professor Sir Konstantin Novoselov, Nobel Laureate for the invention of graphene’s distinctive properties.
One other benefit is that the movies could be transferred to just about any substrate, from organic tissues to microchips. The switch course of, much 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 adversarial reactions. Because of this, they are perfect for use in superior medical applied sciences, together with neural implants like Neuralink’s mind chips.
“This breakthrough has potential purposes in versatile optoelectronics, together with foldable shows, e-paper, and wearable tech, reworking client units like smartphones, tablets, and TVs, whereas additionally paving the way in which for completely new classes of expertise, resembling good contact lenses. In our lab, we’re already working with clear gold movies simply 0.5 nm thick—equal to a couple atomic layers—which holds promise for each cutting-edge applied sciences and elementary physics analysis, ” says Dr. Valentyn Volkov, co-founder and CTO of XPANCEO, an internationally famend skilled within the area of nanophotonics and superior supplies.
The distinctive electrical conductivity and transparency of those movies are key to advancing good contact lens expertise with XR imaginative and prescient, well being monitoring and content-surfing options. The incorporation of those ultrathin movies is crucial, as they permit the mandatory digital parts to be embedded seamlessly into the lens construction, sustaining the thinness of present medical lenses whereas enhancing each performance and luxury.
