  Multidimensional or multiplex bioanalysis represents a crucial approach to
improve diagnostic precision, increase assay throughput and advance fundamental
discoveries in analytical industry, life science and nanomedicine. Along this
line, bio-interfacing magnetic particles have been playing an important role.
Fully exploiting the properties of magnetic particles is the key to tailoring
recent technology development for better translational outcomes. In this
mini-review, typical magnetophysical dimensions of magnetic particles are
introduced. Recent progress of implementing these dimensions with advanced
sensor and actuator technologies in multiplex bioanalysis is discussed.
Outlooks on potential biomedical applications and challenges are provided.
