Abstract
A Lab On a Chip (LOC) comprises: a sample inlet for receiving a liquid sample; and a Sample Preparation Module (SPM) coupled to the sample inlet. The SPM comprises: a mixing chamber; a reagent chamber containing a reagent; a semi-permeable membrane oriented between the mixing chamber and the reagent chamber; and a tuned energy source, wherein the tuned energy source selectively causes contents of the reagent chamber to expand and pass through the semi-permeable membrane into the mixing chamber to mix the reagent with the liquid sample. The LOC further comprises a microchannel coupled to the SPM; a light source; an optic module optically proximate to the microchannel; and a plurality of lenses within the optic module, wherein each lens has a different effective focal length for generating a single composite image of an object passing through the microchannel.
