title = "Two-dimensional freeform optical trapping by surface plasmon enhancement and patterned excitation",
abstract = "In this study, a two-dimensional (2D) freeform optical trapping system based on evanescent wave excitation has been developed. The 2D optical trapping system with surface plasmon (SP) enhancement and patterned excitation via digital micromirror device (DMD) which can provide a strong and freeform intensity distribution on the metal surface. Through a gold film with a thickness of 45 nm in the near infrared region, the SP approach with 40-fold electric field enhancement can enhance the intensity distribution on the metal surface. Unlike a fixed gold pattern film fabricated at a glass surface, the freeform SP-enhanced optical trapping technique is more convenient and efficient for biomedical applications.",
