1. A method for manipulating a particle, comprising:
directing a time-multiplexed electromagnetic beam at a location that will result in interaction between the time-multiplexed electromagnetic beam and the particle;
wherein:
the time multiplexing comprises, over a time segment, directing the electromagnetic beam at at least two different locations;
directing the electromagnetic beam at at least two different locations comprises generating a geometry;
the geometry comprises a trapping geometry configured to fully or partially trap the particle; and
at least one from the following list:
the geometry comprises a trapping geometry configured to fully trap the particle, and further comprising dragging the particle by using the electromagnetic beam to subsequently generate a second trapping geometry configured to fully trap the particle, wherein the second trapping geometry is different from the trapping geometry in at least shape and location; and
at a first time the trapping geometry comprises a partial trap with a first opening having a size, shape, and orientation: at a second time the trapping geometry comprises a partial trip with a second opening having a size, shape, and orientation; and the first opening differs from the second opening in at least one of the following features: size, shape, and orientation.
