Shaping RNA Structures with Metal Ions and Metal Ion Complexes

open access: yesCHIMIA, 2010
The research in our laboratory focuses on the role of metal ions and their complexes in structure formation and folding of nucleic acids. Large catalytic RNAs, like group II introns and some riboswitches, as well as shorter RNAs and DNAs containing modified nucleotides for the assembly of nanodevices are examined. Abundant metal ions like Mg2+

Extraction of Metal Ions with Metal–Organic Frameworks [PDF]

open access: yesMolecules, 2019
Metal–organic frameworks (MOFs) are crystalline porous materials composed of metal ions or clusters coordinated with organic linkers. Due to their extraordinary properties such as high porosity with homogeneous and tunable in size pores/cages, as well as high thermal and chemical stability, MOFs have gained attention in diverse analytical applications.

Metal Ions in Neuroscience [PDF]

open access: yesMetal-Based Drugs, 1997
Metal ions are believed to participate in many neurodegenerative conditions. In excitotoxic cell death there is convincing evidence for the participation of Ca2+ and Zn2+ ions although the exact molecular mechanisms by which these metals exert their effects are unclear.

Metal-Ligand Coordination Induced Ionochromism for π-Conjugated Materials

open access: yesFrontiers in Chemistry, 2020
Recent studies indicated that the toxicity of heavy metal ions caused a series of environmental, food, and human health problems. Chemical ionochromic sensors are crucial for detecting these toxicity ions.

An equivalent metal ion in one- and two-metal-ion catalysis [PDF]

open access: yesNature Structural & Molecular Biology, 2008
Nucleotidyl-transfer enzymes, which synthesize, degrade and rearrange DNA and RNA, often depend on metal ions for catalysis. All DNA and RNA polymerases, MutH-like or RNase H-like nucleases and recombinases, and group I introns seem to require two divalent cations to form a complete active site.

Recent progress on detection of bivalent, trivalent, and hexavalent toxic heavy metal ions in water using metallic nanoparticles: A review

open access: yesResults in Chemistry, 2023
Most of the metal ions are carcinogens and lead to serious health concerns by producing free radicals. Contamination of drinking water sources with heavy metals has a harmful impact on the environment and human health. The most commonly used heavy metals

Bioderived Ionic Liquids with Alkaline Metal Ions for Biodegradable Electrochemical Devices

open access: yes, 2022
An ionic liquid, choline lactate, composed of bioderived materials offers an opportunity to develop electrochemical devices which degrade after use. Although ionic liquids show large potential window, high ionic conductivity, and non-volatility, the ...

Electrochemical Studies for Cation Recognition with Diazo-Coupled Calix[4]arenes

open access: yesJournal of Analytical Methods in Chemistry, 2015
The electrochemical properties of diazophenylcalix[4]arenes bearing ortho-carboxyl group (o-CAC) and ortho-ester group (o-EAC), respectively, in the presence of various metal ions were investigated by voltammetry in CH3CN.
