Disclosed herein is a method of positively detecting toxic materials within a sample, the method including contacting sub-mitochondrial particles with an electron donor. The electron donor is reacted with an electron transfer system of the sub-mitochondrial particles to produce a reactant. A pH indicator has its pH adjusted to be in a range of 9 to 11. The pH indicator is added to each reactant. Color changes in the pH indicator permit the detection of toxins present in the sample.

A carbon nanotube (“CNT”) gas sensor includes a substrate, an insulating layer formed on the substrate, electrodes formed on the insulating layer, and CNT barriers that protrude higher than the electrodes in spaces between the electrodes to form gas detecting spaces. A method of manufacturing the gas sensor includes forming an insulating layer on a substrate, forming an electrode pattern on the insulating layer, coating CNT paste having a thickness greater than a thickness of electrodes in the electrode pattern on the electrodes and the insulating layer, and patterning and firing the carbon nanotube paste, including using a photolithography method, to retain only portions of the CNT paste coated on spaces between the electrodes.

A robot vacuum cleaner having a microbe sensing function is provided. The robot vacuum cleaner includes: a cleaner body which automatically travels in an area to be cleaned; a suction unit which sucks dust in the area to be cleaned into a specific space included in the cleaner body; a microbe contamination sensor which detects a microbe contamination in the area to be cleaned; and a sterilizing unit which sterilizes a corresponding portion according to a microbe contamination measuring signal generated from the microbe contamination sensor. Accordingly, a robot vacuum cleaner directly measures a level of microbe contamination to perform a sterilizing operation according to the result obtained from measurement. As a result, the sterilizing operation is performed sufficiently in a severely contaminated area, the sterilizing operation is performed in a general manner in other areas, and thus a cleaning operation can be rapidly carried out. Therefore, efficiencies in the cleaning and sterilizing operations are improved.

An apparatus for regulating salt concentration, a lab-on-a-chip including the same and a method of regulating salt concentration using the apparatus are provided. The apparatus includes: a reaction chamber that is defined by a cation exchange membrane and an anion exchange membrane and is selected from the group consisting of a biomolecule extraction chamber, an amplification chamber, a hybridization chamber, and a detection chamber; a first electrode chamber that is defined by the anion exchange membrane and a first electrode and includes an ion exchange medium; and a second electrode chamber that is defined by the cation exchange membrane and a second electrode and includes an ion exchange medium. Even without injecting solutions with different salt concentrations into the reaction chamber by operating pumps and valves for each operation stage, the salt concentration can be reversibly regulated in situ by adjusting the polarity, intensity and application time of a voltage.
