1. An apparatus for sorting objects, comprising:

  • a holographic optical trapping apparatus, said optical trapping apparatus which optically traps and sorts a sample of wanted objects from unwanted objects;

    a microfluidics chip containing an input chamber in which said sample is disposed, for streaming said sample from said input chamber to a plurality of output chambers;

    wherein said sorting of said sample into said wanted objects and said unwanted objects takes place at said input chamber using said holographic optical trapping apparatus;

    wherein said sorting removes said wanted objects individually into each of said plurality of output chambers, such that each of said output chambers contains a single wanted object; and

    an apparatus which performs single-cell PCR-based STR analysis on each of said single wanted objects, said apparatus being disposed downstream from said plurality of output chambers.
