Our new paper titled "Ultra-Flexible Giant Magnetoresistance Biosensors for Lab-on-A-Needle Biosensing" is published in Advanced Materials Interfaces.
In this paper, flexible GMR biosensor arrays were fabricated with a two-step backside thinning approach. A lab-on-a-needle sensing platform was developed by attaching the ultra-flexible GMR sensors to the tip of a glass needle with a radius of 1 mm. Despite the tight bending curvature, the detection of OSCA-8 cells was performed successfully.
