These multiple traps serve as a means for an effective trapping of large number of air-born absorbing particles. Confinement of up to a few thousand particles in air with a single beam has been achieved. The ability to capture light-absorbing particles suspended in gases by optical means opens up rich and diverse practical opportunities, including development of photonic shielding/fencing for environmental protection in nanotechnology industry and new methods of touch-free air transport of particles and small containers, which may hold dangerous substances, or viruses and living cells.Keywords: Air transport; Bottle beams; Coherent laser field; Dangerous substances; Living cell; Micro-traps; Multiple particles; Multiple traps; Nanotechnology industry; Opticaltrapping; Single beam; Small containers; Speckle field; Speckle patterns; Bottles; Envir Bottle beam; Environmental protection in nanotechnology industry; Optical trapping in air; Speckle field201010.1117/12.8547692016-02-24
