Abstract While graphene and its derivatives have been suggested as a potential nanomedicine in several biomimetic models, their specific roles in immunological disorders still remain elusive. Graphene quantum dots (GQDs) may be suitable for treating intestinal bowel diseases (IBDs) because of their low toxicity in vivo...

Abstract A popular method used to construct the post structure in traditional Korean buildings is simply placing a stone base on the ground in the natural form and a wooden post on top of the stone base. Interestingly, an illusory visual completion often occurs at the joint where the stone base and the post join. Thus,...

Abstract A discrete core-shell-like micro-light-emitting diode (micro-LED) array was grown on a 100 nm-thick sapphire nano-membrane array without harmful plasma etching for chip singulation. Due to proper design for the sapphire nano-membrane array, an array of multi-faceted micro-LEDs with size of 4 μm × 16 μm was gro...

Seeing subtle nanoparticle differences A challenge in the fabrication of nanoparticles is that even for particles of uniform size, there will still be a distribution in the atomic arrangements and surface capping ligands from one particle to the next. Using liquid-cell transmission electron microscopy, Kim et al. recon...

The transfer of ancestral plastid genomes into mitochondrial genomes to generate mitochondrial plastid DNA (MTPT) is known to occur in plants, but its impacts on mitochondrial genome complexity and the potential for causing a false-positive DNA barcoding paradox have been underestimated. Here, we assembled the organell...

Despite intensive efforts worldwide to contain the spread and find a cure for COVID-19, relatively little is known about the basic biology of the virus. This is now changing. Professor Kim V. Narry, Director of RNA research at the Institute for Basic Science (IBS), Professor Chang Hyeshik from the Department of Biologi...

- Photo-sensitive neuromorphic devices can be used for robots, neural prostheses, and healthcare electronics. - Seoul National University and Inha University, South Korea Researchers at Seoul National University and Inha University in South Korea developed photo-sensitive artificial nerves that emulated functions of a ...

Since the successful isolation of graphene from bulk graphite, remarkable properties of graphene have attracted many scientists to the brand-new research field of 2D materials. However, despite excellent carrier mobility of graphene, direct application of graphene to field-effect transistors is severely hindered due to...

Red, gold, silver spheres on a lipid chip represent metal nanoparticles with strong and distinct scattering signals. The nanoparticles are functionalized with specially designed DNA ligands, and the surface ligands render receptor-floater interactions programmable, thereby transforming a pair of receptor and floater in...

SNU Soft Robotics Research Center has developed a soft wearable hand robot that can aid the hand-disabled by using machine learning algorithm and sensory hardware. Professor Sungho Jo (KAIST) and Kyu-Jin Cho (Seoul National University), a collaboration research team in Soft Robotics Research Center (SRRC), Seoul, Korea...

Professor LEE Byoungho Professor Lee Byoungho (Dept. of Electrical Engineering) has developed a microscope that produces images three to four times better in quality than those of currently existing holographic microscopes. Compared to other holographic microscopes, Professor Lee’s microscopes are able to not only capt...
