An exemplary computer case includes an external shell, a circuit board received in the external shell, and a dehumidification device. The circuit board includes a PCI socket providing an auxiliary power supply when the computer shuts down but the computer case retains electrical connection with an external AC power source. The dehumidification device includes a dehumidification card received in the PCI socket for obtaining the auxiliary power supply therefrom and a remote device. The dehumidification card includes a fan for generating airflow to remove moisture from the computer case and a sensor detecting a humidity inside the computer case. The remote device includes a display unit for displaying the result. When the humidity exceeds a predetermined value, the computer is not powered up until the fan evacuates the excess moisture from the computer case and the humidity falls below the predetermined value.

A method and system for detecting tobacco-specific nitrosamines. The method includes exposing at least one microcantilever beam to a medium, which may contain tobacco-specific nitrosamines, and measuring a deflection of the microcantilever beam, wherein the deflection indicates a presence of tobacco-specific nitrosamines in the medium. The at least one microcantilever beam can include a silicon base layer and a gold-coated receptor layer with a plurality of thiol molecules having a sulfur head and carboxyl-terminated group. The at least one microcantilever beam can include a silicon base layer and a metal or metal oxide coated receptor layer. Alternatively, the microcantilever beam can be formed by co-absorbing tobacco-specific nitrosamines and silane molecules on a silicon microcantilever surface, wherein the template molecules of tobacco-specific nitrosamines physically co-adsorb between the silane molecules. The template molecules of tobacco-specific nitrosamines are then washed away with a solvent to form a silane monolayer having tobacco-specific nitrosamine cavities.

In an improved uncoated microcantilever detector, the sample sites are placed on a separate semi-conducting substrate and the microcantilever element detects and measures the changes before and after a chemical interaction or hybridization of the sites by sensing differences of phase angle between an alternating voltage applied to the microcantilever element and vibration of the microcantilever element. In another embodiment of the invention, multiple sample sites are on a sample array wherein an array of microcantilever elements detect and measure the change before and after chemical interactions or hybridizations of the sample sites.

A method and apparatus are disclosed here for rare target cell enrichment and isolation, where the captured target cells can be individually picked up and used for downstream analysis. This method and apparatus utilize antibodies conjugated microbeads to isolate target cells, use ON/OFF controls for the target cell capturing magnet and the release magnet, such that there is no need to change the cap of the capturing magnet and thus enabling automatic multiple rounds of capturing, washing and releasing cycles to increase the target cell detection sensitivity and reproducibility. A special filter is utilized to effectively remove more than 95% of free unbound microbeads, thus significantly improving the purity of the collected target cells and increasing the data quality of downstream analysis of the single target cells. Lastly, RNA expression patterns are proposed for identifying of certain target cells (e.g. circulating tumor cells and white blood cells).
