A novel protein recognition platform is developed using aptamer‐linked polythiophene nanowires. As the aptamer functionalized poly (3‐methylthiophene) nanowire is treated by the specific protein, resonance Raman and photoluminescence signals are simultaneously enhanced. Statistical analyses deliver the capability of a single conjugated polymer nanowire with phase‐transition characteristics in response to selectivity and concentration.
