Abstract: The present invention relates to a metaallylsilane-based linker compound, a method for preparing same, and the like. The present invention makes it possible to prepare a nanoprobe in which two or more functional molecules are incorporated in a silica nanoparticle that is modified with the linker compound by means of a one-pot process through a continuous bioorthogonal reaction. The nanoprobe of the present invention can be incorporated in a targeting ligand capable of delivering a drug to a specific location, a fluorescent dye for molecular imaging, a radioactive isotope, a magnetic substance, a drug for treatment, and the like, and thus can be used for in vivo molecular imaging, theranostics, and the like.

Abstract: An electronic device and a method of controlling the electronic device are provided. The electronic device includes a main body configured to provide an accommodation space, a speaker module configured to output sound, and an accessory device configured to be accommodated in the accommodation space. In a state where the accessory device is accommodated in the accommodation space, the accessory device is configured to provide a passage that transmits the sound output from the speaker module, and in a state where the accessory device is separated from the accommodation space, the accommodation space provides the passage that transmits the sound output from the speaker module.

Abstract: A mobile device has a solar cell and a rechargeable battery and may be connected with an external power source. A method for a power control of the mobile device allows a continuous and reliable power supply through selective connections with the solar cell, the battery and the external power source. In one embodiment, if the battery is unavailable or absent, the mobile device executes at least one function thereof by using electric power supplied from the solar cell. In another embodiment, if the battery is available with the mobile device powered off, the mobile device charges the battery by using electric power supplied from the solar cell. In still another embodiment, if the battery is available with the mobile device powered on, the mobile device executes at least one function thereof by using electric power supplied from both the solar cell and the battery.
