Two-phase flow in microfluidic-chip design of hydrodynamic filtration for cell particle sorting

As one of the flow-based passive sorting, the hydrodynamic filtration using a microfluidic-chip has shown to effectively separate into different sizes of subpopulations from cell or particle suspensions. Its model framework involving two-phase Newtonian or generalized Newtonian fluid (GNF) was developed, by performing the complete analysis of laminar flow and complicated networks of main and multiple branch channels. To predict rigorously what occurs in flow fields, we estimated pressure drop, velocity profile, and the ratio of the flow fraction at each branch point, in which the analytical model was validated with numerical flow simulations. As a model fluid of the GNF, polysaccharide solution based on Carreau type was examined. The objective parameters aiming practical channel design include the number of the branches and the length of narrow section of each branch for arbitrary conditions. The flow fraction and the number of branches are distinctly affected by the viscosity ratio between feed and side flows. As the side flow becomes more viscous, the flow fraction increases but the number of branches decreases, which enables a compact chip designed with fewer branches being operated under the same throughput. Hence, our rational design analysis indicates the significance of constitutive properties of each stream.

Review on recent development of quinoline for anticancer activities

Quinoline is an efficient scaffold for anticancer drug development as its derivatives have shown potent results through several mechanisms like growth regulators through “apoptosis, disruption of cell migration, inhibition of angiogenesis, modulation of nuclear receptor responsiveness and cell cycle arrest, etc.,” The potential of quinoline derivatives has been proved in several cancer cell lines like breast cancer, colon cancer, lung cancer, colorectal cancer, renal cancer, etc. This review article aims to provide information about the synthesis, potential of the anticancer property, cytotoxicity, and level of clinical treatments, which could lay out the research to develop more effective quinoline-derived anticancer drugs.     

Review on recent advances in the analysis of isolated organelles

The analysis of isolated organelles is one of the pillars of modern bioanalytical chemistry. This review describes recent developments on the isolation and characterization of isolated organelles both from living organisms and cell cultures. Salient reports on methods to release organelles focused on reproducibility and yield, membrane isolation, and integrated devices for organelle release. New developments on organelle fractionation after their isolation were on the topics of centrifugation, immunocapture, free flow electrophoresis, flow field-flow fractionation, fluorescence activated organelle sorting, laser capture microdissection, and dielectrophoresis. New concepts on characterization of isolated organelles included atomic force microscopy, optical tweezers combined with Raman spectroscopy, organelle sensors, flow cytometry, capillary electrophoresis, and microfluidic devices.

Review of development of a silica-based thermoluminescence dosimeter

Development of a silica-based material suitable for thermoluminescence dosimetry (TLD) is described. Doped silica samples were prepared in-house using the sol–gel technique. Results from a micro-X-ray fluorescence (μ-XRF) study of Zn-doped silica have confirmed the capability of the sol–gel processing steps in producing homogeneously doped samples. The ability of sol–gel processing in producing doped samples with different dopant charge states has been illustrated in the case of copper (I)- and copper (II)-doped silica samples. The charge states of the dopants have been verified using the technique of X-ray absorption near-edge structure (XANES). X-ray diffraction (XRD) investigations have shown the structure of samples doped with erbium, copper (I) and copper (II) (listed in order of decreasing effect) to be altered by the dopants, albeit with the samples remaining in an amorphous state. Local structure studies, carried out using the method of extended X-ray absorption fine structure (EXAFS), reveal that in most cases the local environment of the dopant is similar to the respective native structure of the respective metal oxides. Conversely, in a number of cases, the dopant atoms occupy the silicon sites in the silica tetragonal geometry. Thermoluminescence (TL) studies were carried out on aluminium, copper (I), germanium, manganese, tin, and zinc-doped silica samples. Weight for weight, the most sensitive thermoluminescent material was found to be 4.0 mol% aluminium-doped silica, providing 3.5 times the TL yield of TLD100 and 5.4 times that of germanium-doped silica. The photon dose response of aluminium-doped silica was observed to be linear over the range of investigated dose, 0.5–10.0 Gy.
