Abstract: A device for collecting a biological sample from a semi-solid surface. The device has a shaft with a proximate end and a distal end and a tip integrated with the shaft at the proximate end. The tip has a surface adapted to collect microorganisms thereon or release microorganism from, or both, wherein the adapted surface comprises at least one feature of a recess or extension to increase surface area of the tip and collect microorganisms thereon. Examples of such features include microfeatures with dimensions of about 1000 μm or less. Other examples include a pipette tip.
