Abstract: Disclosed are a one-pot biosensor and an immunoassay method using the same. The one-pot biosensor includes a photocatalyst substrate deposited with metal nanoparticles; and a reaction pad which is disposed on an upper surface of the photocatalyst substrate and includes a first binding material-fluorescent material complex specifically binding to a molecule to be detected, and the immunoassay method using the same. The one-pot biosensor may detect a target by once solution injection and has a size enough to be portable. Accordingly, since the one-pot biosensor can detect the target by only once solution injection without a washing step, because of a sensor platform capable of being easily used by an individual other than a diagnostic expert, it is predicted to be positioned as a means capable of confirming the health condition of the individual without seeing the doctor, such as a pregnancy diagnostic kit which has been currently commercialized.

Abstract: A nanofiber membrane includes a polymer nanofiber; and an amphiphilic triblock copolymer bonded to the surface of the polymer nanofiber, the amphiphilic triblock copolymer includes a hydrophobic portion; hydrophilic portions positioned at both ends of the hydrophobic portion; and a low surface energy portion positioned at one end of each of the hydrophilic portions positioned at both ends of the hydrophobic portion, and the hydrophobic portion of the amphiphilic triblock copolymer is bonded to the surface of the polymer nanofiber and the hydrophilic portion and the low surface energy portion are exposed to the outside of the surface of the polymer nanofiber. The membrane simultaneously exhibits hydrophilicity, underwater oleophobicity, and low oil adhesion force, thus has surface segregation properties, and as a result, has an excellent oil permeate flux, exhibits antifouling properties, and can excellently separate oil in water.

Abstract: Disclosed is an image sensor including pixels, and an analog digital converter configured to select output values of the pixels using an analog multiplexer and to simultaneously perform a convolution operation and conversion into a digital signal using a delta-sigma ADC. The size of processed data is reduced, and power consumption is reduced, and thus the image sensor is advantageously applied to a portable device.

Abstract: Antimicrobial peptoids with improved selectivity to bacteria and a use thereof are described. Specifically, the antimicrobial peptoids have high antimicrobial activity and greatly decreased toxicity to animal cells. The antimicrobial peptoids show excellent antimicrobial activity against bacteria and exhibit low cytotoxicity to animal cells due to altered degree of folding in helical structure or altered charge characteristics. Therefore, the antimicrobial peptoids have improved selectivity to bacteria, and thus can be usefully used as antimicrobial compositions.
