This article presents the manipulation and combustion of carbon-based micro particles (polystyrene, active carbon) by optical tweezers. Trap, ignition, and combustion of micro particles are well demonstrated. For polystyrene in water, polystyrene micro particles of 2.9 µm are trapped with increasing laser power. The polystyrene takes reaction and combusts as the laser power of 520 mW. For active carbon in air, both single active carbon and active carbon bundle can be trapped, dragged, oxidized, ignited, and combusted. The drag speed and burning rate of single active carbon of 7.0 µm are 103.7 µm/s and 14.0 µm/s as the minimum ignition power of 3.2 mW. Combustions of single active carbon and bundle are flameless at minimum ignition power. As the power is further enhanced, strenuous oxidation and combustion flame can be observed. For active carbon bundle of 215.7 µm, combustion process sustains 0.72 s as the laser power of 90 mW.

本文介绍了用光镊操作和燃烧碳基微粒​​（聚苯乙烯，活性炭）的方法。微粒的陷阱，着火和燃烧已得到充分证明。对于水中的聚苯乙烯，随着激光功率的增加，会捕获到2.9 µm的聚苯乙烯微粒。聚苯乙烯以520 mW的激光功率发生反应并燃烧。对于空气中的活性炭，单个活性炭和活性炭束都可以被捕集，拖动，氧化，点燃和燃烧。7.0 µm的单个活性炭的拖动速度和燃烧速率分别为103.7 µm / s和14.0 µm / s，这是3.2 mW的最小点火功率。单一活性炭和烟囱的燃烧在最小点火功率下是无焰的。随着功率的进一步提高，可以观察到剧烈的氧化和燃烧火焰。
