Abstract: Point-of-care tools for screening biological samples for markers associated with pathogenic microbial infections. In particular, devices and systems for screening cervical cells for the expression of proteins, which occur as a result of human papillomavirus infection and progression to invasive cervical cancer.
Abstract: A cell sample collection and transfer device is provided. The device may include a plunger configured to slide to a plurality of positions for controlling an expandable tip. The expandable tip may be operable to collect cell samples from a target site. In one example, the expandable tip may be further operable to transfer the collected cell samples when placed in contact with a receiving surface. In another example, the expandable tip may be removed from the device and placed in a storage container for further processing.
