DEVELOPMENT OF CELLULOSIC PAPER-BASED TEST STRIPS FOR Cr(VI) DETERMINATION

open access: yesBioResources, 2009
Paper-based test strips specific for the Cr(VI) determination in aqueous solutions were developed by impregnating a color-forming reagent, diphenylcarbazide, and a quaternary ammonium salt (Aliquat 336) into paper sheets.

Structure of the novel membrane-coating material in proton-secreting epithelial cells and identification as an H+ATPase. [PDF]

open access: yes, 1987
Specialized proton-secreting cells known collectively as mitochondria-rich cells are found in a variety of transporting epithelia, including the kidney collecting duct (intercalated cells) and toad and turtle urinary bladders.

A Microfluidic Multiplex Sorter for Strain Development

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A new multiplex method for high‐throughput screening of yeast strains based on glucoamylase production is presented. Droplets containing single mutant yeast cells are incubated for enzyme production. A sorting platform divides mutants by their high‐ and mid‐activity levels.

Thermal Annealing Enhances Piezoelectricity and Regenerative Potential of PVDF‐TrFE Nanofiber Scaffolds

open access: yesAdvanced Materials Technologies, EarlyView.
Thermal annealing improves the structure, stiffness, and piezoelectric properties of poly(vinylidene flouride‐trifluoroethylene) (PVDF‐TrFE) nanofiber scaffolds. These annealed scaffolds promote Schwann cell proliferation and matrix remodeling in vitro and demonstrate in vivo biocompatibility.

A High‐Throughput AngioPlate Platform with Integrated AngioTEER for Modeling and Monitoring Renal Proximal Tubule Injury

open access: yesAdvanced Materials Technologies, EarlyView.
Renal tubular injury is a major contributor to kidney disease, yet remains poorly understood due to the lack of predictive models. This study presents a high‐throughput 3D renal proximal tubule model on the AngioPlate platform integrated with automated TEER measurements (AngioTEER), enabling real‐time monitoring of drug‐induced nephrotoxicity ...
