A detecting apparatus includes a detecting carrier and a detecting device. The detecting carrier can be moved into a charging frame or anyone of storing frames of a stock room. The detecting device is installed in the detecting carrier and includes a power module and a detecting module. The detecting module is configured to detect environment information corresponding in position to the detecting carrier. The power module is configured to supply power for operating the detecting apparatus. When the detecting carrier is arranged in the charging frame, the power module is spaced away from the charging frame and is charged without contacting the charging frame.

A detecting apparatus includes a detecting carrier and a detecting device. The carrier can be moved into a charging frame or anyone of storing frames of a stock room. The detecting device is installed in the detecting carrier and includes a power module, a detecting module, and a wireless communication module. The wireless communication module can emit an electricity signal according to the power module. The detecting apparatus is selectively operable in a detecting mode and a charging mode. When the detecting apparatus is in the detecting mode, the detecting carrier randomly enters into one of the storing frames, so that the detecting module is operated to detect surroundings. When the detecting apparatus is in the charging mode, the detecting carrier enters into the charging frame, so that the power module is charged.

A detecting apparatus includes a detecting carrier and a detecting device. The detecting carrier can be moved into a charging frame or anyone of storing frames of a stock room. The detecting device is installed in the detecting carrier and includes a power module and a detector for volatile organic compounds (VOC).

A nanostructure sensing device comprises a semiconductor nanostructure having an outer surface, and at least one of metal or metal-oxide nanoparticle clusters functionalizing the outer surface of the nanostructure and forming a photoconductive nanostructure/nanocluster hybrid sensor enabling light-assisted sensing of a target analyte.

The present invention relates to methods and apparatus to monitor and potentially prevent occurrences of lung cancer in patients. The invention includes apparatus and methods to determine a patient's pre-disposition or propensity to acquire lung cancer. Also included are apparatus and methods to monitor for patient biomarkers and for environmental agents, to warn and to take action to reduce exposure to environmental agents and to increase patient screening for the occurrence of lung cancer.

Processes for sensing a variety of toxic chemicals and/or processes for determining the residual life of a filter or filtration system are provided. Exemplary process for sensing a toxic chemical include contacting a toxic chemical, or byproduct thereof, with a sorbent that includes a porous metal hydroxide and a transition metal reactant suitable to react with a toxic chemical or byproduct thereof. The sorbent is contacted with the toxic chemical or byproduct thereof for a sampling time. A difference between a post-exposure colorimetric state of the sorbent and a pre-exposure colorimetric state of the sorbent or control is determined to thereby sense exposure to, or the presence of, the toxic chemical or byproduct thereof.

A molecular detection apparatus according to an embodiment includes: a collection unit collecting a detection target gas containing a molecule to be detected; a substitution unit substituting a part of a molecular structure of at least a part of the molecule to generate a substitution product; a detector including a plurality of detection cells each having a sensor unit and an organic probe disposed at the sensor unit, the organic probe capturing the molecule or the substitution product; and a discriminator discriminating the molecule by a signal pattern based on an intensity difference of detection signals generated with the molecule or the substitution product being captured by the organic probes of the plurality of detection cells.
