• allowed hot spots occurrence. Finally, the test with 4-mercaptophenylboronic acid showed excellent SERS performance of the flexible, horizontally oriented SiNWs in comparison with several other commercially available substrates. Keywords: flexible hot spots; horizontal silicon nanowires; 4

• -plated horizontally synthesized SiNWs with commercially available vertically aligned SiNWs for SERS applications utilizing 4-mercaptophenylboronic acid (4-MPBA) as a test molecule. To the best of our knowledge, flexible horizontally oriented SiNWs and the benefits of flexible hot spots for SERS have not

Afterwards, the ca. 3 × 3 mm2 squared samples were immersed in an ethanol solution of 4-mercaptophenylboronic acid (4-MPBA) for several hours. The morphology of the
