Here, we present an integrated approach to the weakly viscoelastic fluid printability assessment by using global dimensionless criteria (DC). The problem was studied on a model semidiluted polyvinylpyrrolidone water-based ink. For study purpose, ink composition kept as simple possible. First, solution density, viscosity, and surface tension were determined. Obtained data used for testing limitations of DC diagrams already available Newtonian fluids. A replotted version original Kim Baek's...
A new solution for local anesthetic and antibiotic delivery after eye surgery is presented. contact lens-shaped collagen drug carrier was created loaded by Levofloxacin Tetracaine with a riboflavin crosslinked surface layer, thus impeding diffusion. The crosslinking confirmed Raman spectroscopy, whereas the release investigated using UV-Vis spectrometry. Due to barrier, gradually releases into corneal tissue. To test function of carrier, 3D printed device method controlled release, which...
