oscillations<\/a> and effects on metal surfaces. More specifically, the team use surface-enhanced Raman spectroscopy (SERS) plasmonic sensors. This boosts detection capabilities, enabling measurements at ultralow concentrations of biomarkers.<\/p>\nThe study challenges the status quo, proving, as Prof. Xiu Liang says, that water and sensors do not have to be adversaries.<\/p>\n
\u201cIn wearable sensing, hydration is no longer a failure mode \u2014 it becomes the signal.\u201d<\/p>\n
Liang says their design and approach are novel in several ways. They are the first researchers to pack electrical and chemical sensing capabilities into one single layer. Furthermore, their hydration-triggered design solves two problems, because the absorption of sweat also aids adhesion of the device to wet skin.<\/p>\n
Liang says that, unlike most wearable materials research, they did not take a trial-and-error approach. Instead, they performed simulations to predict the amount of water silk fibroin would absorb. To their surprise, the predicted value was unusually close to their experimental value. The team say this gave them confidence they were on target before developing devices.<\/p>\n
Translation into clinical practice<\/p>\n
The researchers have developed a device that harnesses sweat, but what can sweat tell us about how the body is functioning?<\/p>\n
\u201cSweat is full of uric acid, urea, lactate, even biomarkers for neurodegenerative diseases. It offers a rich chemical record of the body status, yet this valuable signal is largely discarded in current clinical practice,\u201d explains Liang.<\/p>\n
This is just the beginning, and further optimization is needed to ensure long-term usability of the e-skin. After that, the team say focus will turn to manufacturing scalability. With low-cost raw materials readily available, the main anticipated issue is batch to batch variability during production. They also acknowledge that multi-centre studies are needed to understand any variability in device measurements across diets, ethnicities, and climates.<\/p>\n
Liang says another hurdle will be obtaining regulatory approval for the device, especially if it is one day offered as a replacement for blood testing.<\/p>\n
Despite these challenges, the team are hopeful moving forward and future studies plan to measure \u03b1-synuclein, a biomarker of neurodegenerative diseases as Liang explains: \u201cFor the 5-10 year horizon, we aim to address the key question raised in our paper\u2019s outlook: can we screen for Parkinson\u2019s disease years before symptoms emerge, by tracking \u03b1-synuclein in sweat? Sweat \u03b1-synuclein is already a well-studied biomarker. If continuous and non-invasive detection can be achieved, we hope to identify at-risk patients five to ten years earlier than current methods.\u201d<\/p>\n
With applicationsfor point-of-care diagnostics and the possibility of integrating other functionalities, Liang believes it\u2019s possible their device could one day be distributed worldwide.<\/p>\n
\u201cWe envision this future scenario: ten years from now, a rural village doctor carries a box of these patches. One is applied to an elderly resident living alone. The next day the township clinic sees that elderly\u2019s ECG and uric-acid curve from the night before, and the doctor tells the family to use less high-purine foods such as organ meats, seafood, rich broths, and arrange a follow-up visit. Low materials cost, scalable production and no bulky equipment required:\u00a0 that is, I think, one of the tangible ways for materials science to advance health equity.\u201d<\/p>\n
