This invention relates to microfluidic apparatus for reading, writing and sorting magnetic tags attached to chemical and biological molecules and other entities. We describe apparatus for separating chemical or biological molecules or moieties each individually attached to a MBM tag miniature multi-bit magnetic tag capable of adopting a plurality of remanent magnetic configurations corresponding to binary information, the apparatus comprising: at least one input for said tagged molecules or moieties; at least two outputs for said tagged molecules or moieties; a microfluidic flow channel incorporating: magnetic readers to read said binary information; magnetic writers to write said binary information; and a switch to direct said tagged molecules or moieties to a selected said output responsive to said binary information. The invention also relates to planar multibit magnetic tags suitable for use with such apparatus.
Apparatus for writing a code onto a magnetic tag having a plurality of magnetically switchable elements for storing said information, said elements being separately switchable at different strengths of an external applied field, the apparatus comprising:
A method of writing a code onto a magnetic tag flowing within a fluidic channel, the method comprising:
A method of reading a code from a magnetic tag having a set of magnetically switchable elements storing said code, each said element of said set having a different coercivity such that said of said set elements are addressable for writing using a ladder of magnetic fields of successive field strengths, said elements being separately switchable at different strengths of an external applied field, the method comprising:
Apparatus for reading information from a magnetic tag having a plurality of magnetically switchable regions storing said information, said regions being separately switchable at different strengths of an external applied field, the apparatus comprising:
