Strong capillarity, chemisorption, and electrocatalytic capability of crisscrossed nanostraws enabled flexible, high-rate, and long-cycling lithiumsulfur batteries ultrasensitive interfacial capacitive pressure sensor based on a randomly distributed. The release of metals and metal-containing compounds into the environment is a growing concern in developed and developing countries, as human exposure to metals is associated with adverse health effects in virtually every organ system. Unfortunately, quantifying metals in the environment is expensive analysis costs using certified laboratories typically exceed 100sample, making the routine. Dual-quenching electrochemiluminescence strategy based on three-dimensional metal-organic frameworks for ultrasensitive detection of amyloid-beta. Read the latest articles of analytica chimica acta at sciencedirect. Biomimetic autoseparation of leukocytes from whole blood in a microfluidic device. Although each novel scientific result has its roots in some earlier findings, it is probably safe to state that different independent achievements in the mid-1960s marked the starting point of modern potentiometry. In 1967, ross described the first membrane electrode based on a liquid ion exchanger and bloch and co-workers introduced the first. A previously reported dnazyme-based biosensor for pb2 has shown high sensitivity and selectivity at 4 c. In the system, the substrate and the enzyme strand of the dnazyme are labeled with a fluorophore and a quencher, respectively. In the presence of pb2, the substrate strand is cleaved by the enzyme strand, and the release of the cleaved fragment results in significant fluorescence increase. 2 citescore measures the average citations received per peer-reviewed document published in this title. Citescore values are based on citation counts in a range of four years (e. 2016-2019) to peer-reviewed documents (articles, reviews, conference papers, data papers and book chapters) published in the same four calendar years, divided by the number of. Analytica chimica acta has an open access mirror journal analytica chimica acta x, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Analytica chimica acta provides a forum for the rapid publication of original research, and critical, comprehensive reviews dealing with all aspects of fundamental and applied modern analytical chemistry.
