摘要： A system is provided for performing metal trace analysis on a liquid sample. A sample holder holds an analysis substrate that includes a reference region and at least one test region. An ultraviolet (UV) light source emits ultraviolet light illuminating the liquid sample. An optical sensor detects radiation emanating from the liquid sample and converting the detected radiation into an electrical signal. A microcontroller processes the electrical signal. An external interface transmits the processed electrical signal to an external device. The analysis substrate is configured for manual movement by a user. A tracking system detects a sample scanning location for the metal trace analysis, and includes a light source, other than the UV light source, and another optical sensor. The other optical sensor detects light emitted by the light source.

摘要： An Integrated Circuit (IC) chip with a lab-on-a-chip, a method of manufacturing the lab-on-a-chip and a method of using the lab-on-a-chip for fluid flow analysis in physical systems through combination with computer modeling. The lab-on-a-chip includes cavities in a channel layer and a capping layer, preferably transparent, covering the cavities. Gates control two dimensional (2D) lattice structures acting as heaters, light sources and/or sensors in the cavities, or fluid channels. The gates and two dimensional (2D) lattice structures may be at the cavity bottoms or on the capping layer. Wiring connects the gates and the 2D lattice structures externally.
