Abstract: Embodiments of the present disclosure relate to a magnetic bead platform for isolating sperm cells from biological samples. In some embodiments, such magnetic bead platforms integrate recognition reagents to its surface to bind target cells, such as sperm cells. Such embodiments provide the ability to at least one of rapidly isolate and quantitate sperm cells from biological samples as occur in sexual assault evidence, for example, thereby enhancing identification of suspects in these cases and contributing to the safety of society.
