A method for developing the spherical surface‐enhanced Raman scattering (SERS) fibre probe is presented cladded with the silver nanoparticles to detect the fluorochrome molecular. By controlling the diameter of the fibre ball, the excellent SERS enhancement effect has been achieved up to about 10 5 due to the plasmonic silver nanoparticles, the coated parylene‐C dielectric layer and the low‐energy loss in the spherical resonant cavity. Meanwhile, the repeatability and stability of the fibre probe have been explored by coating the parylene‐C with the error of 1%. It has proved an important superiority for potential commercial applications of this technique to detect the bio‐molecular with the advantages of high sensitivity, high stability and low cost.
