Tracing app technology: an ethical review in the COVID-19 era and directions for post-COVID-19.

Unlabelled: We conducted a systematic literature review on the ethical considerations of the use of contact tracing app technology, which was extensively implemented during the COVID-19 pandemic. The rapid and extensive use of this technology during the COVID-19 pandemic, while benefiting the public well-being by providing information about people's mobility and movements to control the spread of the virus, raised several ethical concerns for the post-COVID-19 era. To investigate these concerns for the post-pandemic situation and provide direction for future events, we analyzed the current ethical frameworks, research, and case studies about the ethical usage of tracing app technology.

COVID-19, Scarce Resources and Priority Ethics: Why Should Maximizers Be More Conservative?

Background: The principle of maximization, which roughly means that we should save more lives and more years of life, is usually taken for granted by the health community. This principle is even more forceful in crises like the COVID-19 pandemic, where we have scarce resources which can be allocated only to some patients. However, the standard consequentialist version of this principle can be challenging particularly when we have to reallocate a resource that has already been given to a patient.

Phenyl alanine & Tyrosine Amino acids Coated Magnetic Nanoparticles: Preparation and Toxicity study.

In this study we reported the synthesis of L-phenyl alanine (Phe) & L-tyrosine (Tyr) Natural Amino acids coated iron oxide magnetic nanoparticles under one-pot and in situ reaction. Functionalized iron oxide magnetic nanoparticles were characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Vibrating Sample Magnetometer (VSM), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM) techniques. Cellular toxicity of amino acids coated iron oxide magnetic nanoparticles was also investigated on HEK-293 cell lines.
