摘要：

We explore a simple, inexpensive approach to large particle manipulation using diode laser bar optical trapping. This method overcomes limitations that prevent conventional point laser traps from effectively directing large particles. Expanding a previously developed line optical trap model into larger particle regimes, we verify and examine the advantages and limitations of diode laser bar trapping for manipulating particles greater than 100 mu m in diameter within fluidic environments for biochemical, biological, and biomedical applications.
