“…No such NTU turbidity differences in RPMI were observed with TiO 2 . The difference in turbidity signal levels between CB and TiO 2 must be imputed for carbon to the black colored suspension that it is necessary to take into account [ 18 ]. Complementary light microscopic analysis showed that NPs in RPMI 1640 were less but still aggregated.…”

Background: The ability of nanoparticles to cross the lung-blood barrier suggests that they may translocate to blood and to targets distant from their portal of entry. Nevertheless, nanotoxicity in organs has received little attention. The purpose of this study was to evaluate nanotoxicity in renal cells using in vitro models. Various carbon black (CB) (FW2-13 nm, Printex60-21 nm and LB101-95 nm) and titanium dioxide (TiO 2 -15 and TiO 2 -50 nm) nanoparticles were characterized on size by electron microscopy. We evaluated theirs effects on glomerular mesangial (IP15) and epithelial proximal tubular (LLC-PK 1 ) renal cells, using light microscopy, WST-1 assay, immunofluorescence labeling and DCFH-DA for reactive oxygen species (ROS) assay.

“…The turbidity assay measures the degree of light scattering through a sample with suspended particles. Turbidity depends mainly on the concentration of the suspended particles, the size distribution of the particles in the liquid phase and the difference in the refractive index between the particles and the suspending medium [47,48]. Microbiological instability or increase in the particle size of the suspended particles as a result of aggregation will result in an increase in the RT of the liquid [46].…”

Non-ionic surfactant vesicles (NISV) are colloidal particles that provide a useful delivery system for drugs and vaccines. One of the methods that is used for NISV preparation is microfluidics in which the lipid components dissolved in organic phase are mixed with an aqueous medium to prepare the particles through self-assembly of the lipids. In this work, we examined the effect of using different types of aqueous media on the characteristics of the NISV prepared by microfluidics. Five aqueous media were tested: phosphate buffered saline, HEPES buffer, Tris buffer, normal saline and distilled water. The resulting particles were tested for their physical characteristics and cytotoxicity. The aqueous media were found to have significant effects on the physical characteristics of the particles, as well as their overall stability under different conditions and their cytotoxicity to different human cell lines. Careful consideration should be taken when choosing the aqueous media for preparing NISV through microfluidics. This is an important factor that will also have implications with respect to the entrapped material, but which in addition may help to design vesicles for different uses based on changing the preparation medium.

“…Two main methods are available for measuring solubility. One is based on measuring the amount of light scattered by the particles in a solution using nephelometers [ 11 , 12 ] and turbidimeters [ 13 , 14 ], the other involves using ‘excess solid’ or ‘excess solvent’ methods [ 1 ]. The former, which uses light transmission and scattering to determine whether a solution is soluble, requires separate sampling and preparation steps.…”

Solubility measurements are essential in various research and industrial fields. With the automation of processes, the importance of automatic and real-time solubility measurements has increased. Although end-to-end learning methods are commonly used for classification tasks, the use of handcrafted features is still important for specific tasks with the limited labeled images of solutions used in industrial settings. In this study, we propose a method that uses computer vision algorithms to extract nine handcrafted features from images and train a DNN-based classifier to automatically classify solutions based on their dissolution states. To validate the proposed method, a dataset was constructed using various solution images ranging from undissolved solutes in the form of fine particles to those completely covering the solution. Using the proposed method, the solubility status can be automatically screened in real time by using a display and camera on a tablet or mobile phone. Therefore, by combining an automatic solubility changing system with the proposed method, a fully automated process could be achieved without human intervention.
