Sensor for Advanced Breath-analysis Technology

Caption: This image shows a new type of sensor for an advanced breath-analysis technology that rapidly diagnoses patients by detecting "biomarkers" in a person's respiration in real time. Researchers used a template made of micron-size polymer particles and coated them with much smaller metal oxide nanoparticles. Using nanoparticle-coated microparticles instead of a flat surface allows researchers to increase the porosity of the sensor films, increasing the "active sensing surface area" to improve sensitivity.
