Latest Patents

One of Qing He's latest patents focuses on an IC-processed polymer nano-liquid chromatography system on-a-chip and the methods for its production and use. This innovation relates to packed-column nano-liquid chromatography (nano-LC) systems integrated on-chip. The microfabricated chip includes essential components: a column, filters, an injector, and a detector, all fabricated in a process compatible with integrated circuit technology. The system is versatile, allowing for various stationary phases that support a range of chromatography forms, including reversed-phase, normal-phase, adsorption, size-exclusion, affinity, and ion chromatography. Notably, the system features a cross-channel injector for nanoliter/picoliter-scale sample injection and an integrated electrochemical/conductivity sensor that measures separation signals at the outlet. The introduction of a self-aligned channel-strengthening technique increases the pressure handling capacity of the microfluidic system, making it capable of enduring the high pressures typical of high-performance liquid chromatography (HPLC). This innovation successfully demonstrates on-chip sample injection, separation, and detection of anions in water via ion-exchange nano-LC.
