However, the lack of reproducibility in Raman signals limits this technique in quantitative analyses. Herein, we propose a straightforward approach to perform quantitative SERS analyses in homogeneous aqueous environment by using a flexible SERS membrane to eliminate the limitations in solid state measurement. 聽The flexible SERS chip is composed of a transparent polymer membrane and well-patterned plasmonic nanodimers on its undersurface (figure 1). 聽The chip spreads and floats on aqueous solution, working as a real-time interface sensor to monitor the absorption and reaction dynamics in solution. 聽In our experiment, a quantitative SERS agreement with excellent relative standard deviation (< 10%) for Rhodamine 6G molecule is established with a detection limit down to 10<sup>-13</sup> M. 聽This robust and feasible approach significantly simplifies sample pretreatment procedures confronting practical applications, providing a universal platform for in-situ and real time monitoring of chemical reactions and elucidating reaction mechanisms.</p> </p> </div> <h2>Authors</h2> <ol> <li> <u>Qi Hao</u> (IFW Dresden) </li> <li> Libo Ma (IFW Dresden) </li> <li> Oliver G.
