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 µm in diameter within fluidic environments for biochemical, biological, and biomedical applications.
