  • Patent number: 11332617
    Abstract: A polyarylene sulfide resin composition contains a polyarylene sulfide resin, a transition metal particle, a fibrous inorganic filler, and an inorganic nucleating agent, and a molded article made from the resin composition. The resin composition has excellent mechanical, corrosion, and haze properties, and heat resistance. The resin composition prevents corrosion of a mold and deterioration in the durability of a manufactured product upon injection by effectively removing halogen-based impurities, and also has excellent mechanical, corrosion, and haze properties, and heat resistance. A molded article manufactured from the resin composition satisfies the standards required for components of a vehicle and an electric/electronic device.

  • Publication number: 20220032300
    Abstract: A multiplex PCR chip capable of simultaneously detecting multiple target genes and a multiplex PCR method using the same are proposed. More specifically, in the multiplex PCR chip and multiplex PCR method, after a plurality of spatially separated particle-forming grooves is formed in one or more reaction chambers and a probe in a solution state is injected into the particle-forming grooves, planar shapes of the particle-forming grooves are varied or shapes and patterns of particle holders respectively formed on inner surfaces of the particle-forming grooves are varied, and the probe including primers specifically hybridizing with sequences of different nucleic acid molecules is injected into the particle-forming grooves, whereby simultaneous multiplex detection is possible by allowing multiple target genes to be detected on the basis of positions and shapes of the probe particles and the shapes and patterns of the particle holders respectively formed inside of the probe particles.
