Additive manufacturing is a manufacturing technology used to form structures layer by layer. Micro-level additive manufacturing has been used in many different areas. However, this kind of technology still has much room for development at the nano-level. A new additive nanomanufacturing approach named opto-thermalmechanical nanoprinting (OTM-NP) is introduced. The OPM-NP allows us to selectively release a nanoparticle from a donor substrate and transfer it to a receiver substrate. The receiver substrate is placed a few micrometers above the donor substrate and there is no limitation on the type of substrate used in this technology. In this project, the following three experiments are conducted to demonstrate the capability of the OTM-NP: (1) we studied the releasing probabilities of different sizes of gold nanoparticles (GNP) on different donor substrates. (2) we demonstrated transfer of GNPs to a capillary tube tip and a liquid surface. (3) we demonstrated the transfer of GNPs to an optical fiber tip. The optical fiber tips with GNPs on manufactured on its surface are used for enhanced sensing of R6G molecules. We demonstrated that the optical fiber tips with GNPs on it can enhances the Raman signal of R6G molecules by 21 times compared to that without the GNPs. The amount of Raman enhancement on the fiber tip depends on the number of GNPs that are manufactured on its surface and can be precisely controlled by using the OTM-NP method. The OTM-NP method can be potentially used in other areas where the number of nanoparticles on a surface has to be precisely controlled.
