Abstract: Microfluidic devices including a microfluidic channel with at least one surface having a plurality of chiral nanoparticles disposed thereon include a light-absorbing material (e.g., gold) and a targeting ligand capable of binding to a bioactive target analyte in a biological fluid sample. The bioactive target analyte can indicate presence of cancerous cells or mutated proteins in the biological fluid sample taken from a subject. Chiral gold nanoparticle layer-by-layer assembled onto a microfluidic device can rapidly isolate and profile cancer-associated exosomes directly from blood plasma using their own unique chiral signal. Exosomes from lung cancer patients can be distinguished from healthy donor exosomes by chiroptical spectroscopic signatures of biomolecular components. Mutation/deletion of epidermal growth factor receptor are also characterized, suggesting the possibility for in-depth mutation profiling in addition to cancer diagnostics. Methods of detecting bioactive target analytes and making the microfluidic devices are also provided.

Abstract: A clock signal processor includes a duty cycle corrector, a switch point calculator, and a multiplexer. The duty cycle corrector generates a second clock signal by modifying a duty cycle of a first clock signal. The switch point calculator activates a switch signal at an end of a latency period in which a read command is provided to a non-volatile memory device and an invalid data is read from the non-volatile memory device. The multiplexer outputs one of the first and second clock signals as a third clock signal based on the switch signal.

Abstract: Embodiments described herein provide approaches for benefit promotion advertising in an augmented reality (AR) environment. Specifically, users are presented with an advertisement overlay generated for a video sequence from a mobile device. The advertisement overlay comprises a set of AR objects, and an incentive to the user to interact with the AR objects of the advertisement overlay. Responses from the user are recognized, and a benefit is provided to the user based on the response to the incentive. As such, advertisement campaigns in the AR environment are made more appealing to the user and, consequently, more effective for the advertiser.

Abstract: A field emission device having a simple structure and capable of readily changing emission colors of light by adjusting emission intensity of red, green and blue light is provided. In the field emission device, current that flows into each cathode electrode block is adjusted according to a very low control pulse signal of 0 to 5 V with a predetermined voltage applied to an anode electrode and a gate electrode over time, so that emission intensities of red, green and blue are individually adjusted. Therefore, the current that flows into each cathode electrode block is adjusted in a simple manner using a control pulse signal of a low level without a separate pulse driving high-voltage power supply, so that emission intensities of red, green and blue can be arbitrarily adjusted and emission colors of the field emission device can be readily changed.
