Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Department of Chemical Engineering Reports Findings in Nanoparticles (Enhancement of cell membrane permeability by using charged nanoparticles and a weak external electric field)
2023 NOV 01 (NewsRx) -- By a News Reporter-Staff News Editor at Japan Daily Report -- New research on Nanotechnology - Nanoparticles is the subject
Article Description
Because the cell membrane is the main barrier of intracellular delivery, it is important to facilitate and control the translocation of extracellular compounds across it. Our earlier molecular dynamics simulations suggested that charged nanoparticles under a weak external electric field can enhance the permeability of the cell membrane without disrupting it. However, this membrane permeabilization approach has not been tested experimentally. This study investigated the membrane crossing of a model compound (dextran with a M of 3000-5000) using charged nanoparticles and a weak external electric field. A model bilayer lipid membrane was prepared by using a droplet contact method. The permeability of the membrane was evaluated using the electrophysiological technique. Even when the applied electric field was below the critical strength for membrane breakdown, dextran was able to cross the membrane without causing membrane breakdown. These results indicate that adding nanomaterials under a weak electric field may enhance the translocation of delivery compounds across the cell membrane with less damage, suggesting a new strategy for intracellular delivery systems.
