Femtosecond Laser Nanoprocessing and Bio-Applications

Abstract

The use of small particles has expanded the capability of ultrafast laser processing and provides precise processing in nanometer-scale space that overcomes the theoretical diffraction-limited spatial resolution. Recently precise laser processing is showing attractive developments in biomedical applications including drug delivery and cell stimulation. This review gives the fundamentals of laser processing by enhanced optical fields and its calculational studies. We also describe the recent progresses in bioapplications that use femtosecond lasers and small particles.
