LMU researchers have developed a modular strategy to easily adapt biosensors for various applications, potentially accelerating the development of new diagnostic tools for research. The sensor’s design utilizes a DNA origami scaffold with fluorescent dyes that change in response to conformational changes, providing clearer and more precise signals compared to systems with smaller changes. The origami scaffold can be modified with docking sites for different biomolecular targets, allowing for deliberate adaptation and optimization through additional binding sites or stabilizing DNA strands. The flexibility of the system allows for specific control of sensitivity without altering biomolecular interactions, creating a major advantage for the sensor.
The origami scaffold’s design enables multiple molecular interactions between the target molecule and sensor to be queried simultaneously, leading to interesting cooperative effects that can enhance sensor sensitivity. This feature allows for the sensor’s sensitivity to be specifically controlled without affecting the strength of the target molecule’s binding to its binding site. The researchers aim to further optimize the sensor for biomedical and other applications, potentially developing sensors that can monitor various parameters and release active agents under specific conditions. The versatility and adaptability of the sensor make it a promising tool for a wide range of applications in research and diagnostics.
