Investigation on Rosehip Fruit Tea, Linden Herbal Tea, Sage Herbal Tea and Green Tea-are thay acidic or not?

Tea is a widely-consumed daily life product, which is claimed to be very advantageous for health. But it may have negative effects on health, too. Consuming tea with a hungry stomach causes stomachache, and doctors say that this is because the tea is acidic. This investigation aims to determine if four types of teas (Rosehip Fruit tea, Linden Herbal Tea, Sage Herbal Tea and Gren Tea with Lemon) are acidic or not. This investigation is important in the sense that the way the tea is consumed may be limited. Determining if the tea is acidic or not may effect the habits of many people about tea consumption. In order to determine if the tea is acidic or not, I used the titration method. Titration is a technique in which the molarity of a solution can be found by using a strong base or acid with a known molarity and volume. At the end of my trials, I found out that these four types of teas are all acidic. These results showed me that Rosehip Fruit Tea is the most acidic one among all, and the Linden Herbal Tea is the one closest to the neutral. When an order is made between the acidities tea types, I reached to the conclusion below: Rosehip tea > Green tea with Lemon > Sage tea > Linden te

Integrated Microfluidics for Single‐Cell Separation and On‐Chip Analysis: Novel Applications and Recent Advances

From deciphering infection and disease mechanisms to identifying novel biomarkers and personalizing treatments, the characteristics of individual cells can provide significant insights into a variety of biological processes and facilitate decision-making in biomedical environments. Conventional single-cell analysis methods are limited in terms of cost, contamination risks, sample volumes, analysis times, throughput, sensitivity, and selectivity. Although microfluidic approaches have been suggested as a low-cost, information-rich, and high-throughput alternative to conventional single-cell isolation and analysis methods, limitations such as necessary off-chip sample pre- and post-processing as well as systems designed for individual workflows have restricted their applications. In this review, a comprehensive overview of recent advances in integrated microfluidics for single-cell isolation and on-chip analysis in three prominent application domains are provided: investigation of somatic cells (particularly cancer and immune cells), stem cells, and microorganisms. Also, the use of conventional cell separation methods (e.g., dielectrophoresis) in unconventional or novel ways, which can advance the integration of multiple workflows in microfluidic systems, is discussed. Finally, a critical discussion related to current limitations of integrated microfluidic single-cell workflows and how they could be overcome is provided
