Sample preparation can include obtaining a sample in the form of a liquid mixture and forcing the liquid mixture through a cavitation chamber at an optimal pressure for separating pathogens from particles in the mixture without fragmenting at least 30% of the pathogens. Apparatuses used for sample preparation methods can include a fluid circuit, a cavitation chamber incorporated into the fluid circuit and having a channel with first, second, and third cross-sectional areas, the second cross-sectional area being downstream of and smaller than the first cross-sectional with respect to fluid flow through the fluid circuit and the third cross-sectional area being larger than and downstream of the second cross-sectional area with respect to fluid flow through the fluid circuit. The apparatus can include a pump in fluid communication with the cavitation chamber and a pressure sensor positioned upstream of the cavitation chamber.
