Abstract:
High-performance biosensors are crucial for elucidating the spatiotemporal regulatory roles and dynamics of membrane lipids, but there is a lack of improvement strategies for biosensors with low sensitivity and low-content substrates detection. Here we developed universal optogenetic strategies to improve a set of membrane biosensors by trapping them into specific region and further reducing the background signal, or by optically-controlled phase separation for membrane lipids detection and tracking. These improved biosensors were superior to typical tools and light simulation would enhance their detection performance and resolution, which might contribute to the design and optimization of other biosensors.
