AI Article Synopsis

  • The study explores how glutathione molecules attach to silver nanoparticles using surface-enhanced Raman scattering (SERS) and heat-based sensing techniques.
  • It evaluates the impact of various chemical environments on the orientation and configuration of these molecules on the silver surfaces.
  • By analyzing SERS signals from different functional groups of glutathione, the research identifies their affinity to the silver nanoparticles and reveals their adsorption orientations.

Article Abstract

In this study, surface-enhanced Raman scattering (SERS) in combination with a heat-induced sensing technique has been applied for investigating molecular orientations of glutathione molecules adsorbed on silver colloidal nanoparticles under different chemical environments, which has enabled us to further study how glutathione molecules are adsorbed on the silver surfaces. Factors that may affect the configurations of glutathione molecules adsorbed on the silver nanocolloids have been investigated. By observing the relative enhancement factors of SERS bands due to individual functional groups contributed from different terminals, the affinity between the different functional groups of glutathione and the silver surfaces under different conditions has been sorted and the orientations of glutathione molecules adsorbed on the silver surfaces have been investigated.

Heavy metalloid stress such as arsenic (As) toxicity and nutrient imbalance constitute a significant threat to plant productivity and development. Plants produce sulfur (S)-rich molecules like glutathione (GSH) to detoxify arsenic, but sulfur deficiency worsens its impact. Previous research identified Arabidopsis thaliana ecotypes Koz2-2 (tolerant) and Ri-0 (sensitive) under low-sulfur (LS) and As(III) stress.

The presence of redox-active molecules containing catenated sulfur atoms (supersulfides) in living organisms has led to a review of the concepts of redox biology and its translational strategy. Glutathione (GSH) is the body's primary detoxifier and antioxidant, and its oxidized form (GSSG) has been considered as a marker of oxidative status. However, we report that GSSG, but not reduced GSH, prevents ischemic supersulfide catabolism-associated heart failure in male mice by electrophilic modification of dynamin-related protein (Drp1).

Article Synopsis
  • Chemotherapy's effectiveness is hampered by side effects, lack of specificity, and drug resistance, prompting the development of a novel small molecule conjugate called TDK-HCPT for targeted treatment.
  • TDK-HCPT utilizes a unique design featuring thiamine disulfide and thioketal subunits that allow for selective targeting of tumor cells and retention of chemotherapy drugs like HCPT inside them.
  • This innovative approach has demonstrated a significant reduction in cancer cell migration, tumor growth, and tumorigenesis rates in both lab studies and animal models.
