Volatile organic compound (VOC) detection is critical for controlling industrial and commercial emissions, environmental monitoring, and public health.
Simple, portable, rapid, and low-cost VOC sensing platforms can provide the benefits of on-site and real-time monitoring anytime and anywhere.
In particular, equipment-free and power-free detection by the naked eye would be among the most practical and useful approaches for field use.
In this work, we create a novel paper-based cantilever sensor array for simple and rapid naked-eye VOC detection without any power source, electronics, or readout equipment.
