1. A method for concentrating and isolating biological cells from a sample, comprising:

contacting a solid phase having a rough and/or structured surface with the sample by placing the solid phase into a cavity containing the sample;

agitating and/or aspirating the sample with the solid phase having the rough and/or structured surface to adsorb the biological cells onto the solid phase.
