Researchers at California Institute of Technology have created core-shell nanoparticles that can be used to print biosensors for monitoring various biomarkers in bodily fluids. The new particles are highly versatile and can bind to multiple molecules, including amino acids, hormones, and drugs.
The breakthrough allows for the creation of portable sensors that can measure levels of substances such as vitamin C, tryptophan, and creatinine with high accuracy. These biomarkers are commonly used to monitor kidney function and patients with long COVID.
Using a single array of nanoparticles, researchers can create multiple sensors in one go, making it easier to mass-produce these devices. This technology has the potential to revolutionize disease diagnosis and treatment by providing rapid and portable diagnostic tools for various conditions.
