Physical Surface Modification of Carbon-Nanotube/Polydimethylsiloxane Composite Electrodes for High-Sensitivity DNA Detection.

The chemical modification of electrode surfaces has attracted significant attention for lowering the limit of detection or for improving the recognition of biomolecules; however, the chemical processes are complex, dangerous, and difficult to control. Therefore, instead of the chemical process, we physically modified the surface of carbon-nanotube/polydimethylsiloxane composite electrodes by dip coating them with functionalized multi-walled carbon nanotubes (F-MWCNTs). These electrodes are used as working electrodes in electrochemistry, where they act as a recognition layer for sequence-specific DNA sensing through π-π interactions.

Synergistic Effects of Self-Assembled Monolayers in Solution-Processed 6,13-Bis(triisopropylsilylethynyl)Pentacene Transistors.

This study clarifies the synergistic effects of electrode and dielectric SAMs on the behavior of solution-processed organic field-effect transistors (OFETs). Utilization of a self-consistent device model enables a physically robust treatment of the measured electrical characteristics of the OFETs, thus providing highly reliable materials, interface, morphology, and transport parameters.

We demonstrate that the quality of the CHNHPbI perovskite film was improved with increased crystallinity and reduced pinholes by doping the perovskite with 5 mol% cesium.

The Histone Deacetylase Inhibitor (MS-275) Promotes Differentiation of Human Dental Pulp Stem Cells into Odontoblast-Like Cells Independent of the MAPK Signaling System.

The role of dental pulp stem cells (DPSCs) in dental tissue regeneration is gaining attention because DPSCs can differentiate into odontoblasts and other specialized cell types.

The use of HDAC inhibitor to control this is increasing and has been widely studied by many researchers.

Pigmentation Effect of Rice Bran Extract in Hair Follicle-Like Tissue and Organ Culture Models.

Background: Melanogenesis is a biological process resulting in the production of melanin pigment, which plays an important role in the prevention of sun-induced skin injury and determines the hair and skin color. Melanin has the ability to block ultraviolet radiation and scavenge free oxygen radicals, thus protecting the skin from their harmful effects. Agents that increase melanin synthesis in melanocytes may reduce the risk of photodamage and skin cancer.

Extremely Low-Frequency Electromagnetic Fields Increase the Expression of Anagen-Related Molecules in Human Dermal Papilla Cells via GSK-3β/ERK/Akt Signaling Pathway.

Despite advances in medical treatments, the proportion of the population suffering from alopecia is increasing, thereby creating a need for new treatments to control hair loss and prevent balding. Human hair follicle dermal papilla cells (hDPCs), a type of specialized fibroblast in the hair bulb, play an essential role in controlling hair growth and in conditions like androgenic alopecia. This study aimed to evaluate the intensity-dependent effect of extremely low-frequency electromagnetic fields (ELF-EMFs) on the expression of anagen-related molecules in hDPCs in vitro.

Agents that increase melanin synthesis in melanocytes may reduce the risk of photodamage and skin cancer.

Highly selective, reusable electrochemical impedimetric DNA sensors based on carbon nanotube/polymer composite electrode without surface modification.

We fabricated a composite of multi-walled carbon nanotube and polydimethylsiloxane and utilized it as an electrode for DNA sensing using electrochemical impedance spectroscopy. Without any surface modification or probe immobilization, often necessary for other electrodes, this electrode also acts as a recognition layer for DNA via π-π interactions between the multi-walled carbon nanotube and DNA. This electrode is easily reusable via a simple cleansing process, because there are no covalently bonded adsorbates on the electrode.

Alcohol based vapor annealing of a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) layer for performance improvement of inverted perovskite solar cells.

In this study, we introduced alcohol based vapor annealing of a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) layer for fabricating high-performance inverted perovskite solar cells. Atomic force microscopy measurements and atomistic theoretical simulations indicated that phase separation between PEDOT and PSS was enhanced by this annealing, improving the hole conductivity at the PEDOT:PSS layer.

Sequence-specific detection of DNA using functionalized graphene as an additive.

We developed a simple and sensitive method for sequence-specific DNA detection using functionalized graphene (FG) and methylene blue (MB). Target DNA with a specific sequence was identified by differential-pulse voltammetry, which produces a change in the redox currents of the incorporated MB. FG played a critical role in enhancing the sensitivity of DNA detection and reduced the concentration of MB substantially near the electrodes when the sequence of the target DNA was not complementary to that of the probe by adsorbing the single-stranded DNA with the bound MB, and sinking.

A radical polymer as a two-dimensional organic half metal.

Given that half-metals are promising futuristic materials for spintronics, organic materials showing half-metal character are highly desirable for spintronic devices, not only owing to their weak spin-orbit and hyperfine interactions, but also their light and flexible properties. We predict that a two-dimensional organic 2,4,6-tri-(1,3,5-triazinyl)methyl radical polymer has half-metallic properties as well as a spontaneous magnetic ordering at ambient temperature. The quantum transmission is studied based on the nonequilibrium Green function theory coupled with density functional theory.
