    has developed a bio-monitoring fluorescent device that can be used to diagnose a variety of organ diseases
    In
    2020, the Ukrainian National institute of physics and biophysical applications
    developed a fluorescent device that can be used to monitor ultra-low concentrations of acetone and ammonia molecules in exhaled gases and vapors.
    can be used to diagnose liver and kidney insanity and lung cancer, acetone can be used for the diagnosis of diabetes, adenitis, heart failure and other diseases. Using the high sensitivity of fluorescent signals to certain reagents, based on the ability of organic dyes to interact with acetone and ammonia molecules and change their fluorescence response, Ukrainian researchers have developed a fluorescent device for detecting ultra-low concentrations of acetone and ammonia molecules. The "heart" of the device sensor is a sensitive film in the silicon dioxide substitut, which introduces the caramel family of organic dyes as a sensitive ingredient and quantum dots as fluorescent signal amplifiers.

    the British correspondent Tian Discipline
    2020 is the year that British scientists have doubled their achievements in the field of biotechnology research.
    in the field of embryology, researchers used human cells to develop three-dimensional tissue models of early human embryonic development, marking an important step in simulating human development.
    University of Oxford have studied how cells in the brain work together to connect memories of different experiences, allowing us to make escientistic assumptions in our daily lives.
    University College London researchers used next-generation sequencing (NGS) technology to find "fingerprints" (early circulating biomarkers) representing prostate tissue in the blood that can be used to determine whether cancer cells are active and spreading.
    british and Belgian scientists have worked together to create the first atlas of human thymus tissue, revealing the origin of T-cells, an important immune cell.
    In order to overcome the shortcomings of vaccine preservation that requires low or ultra-low temperatures, the researchers cleverly put a silicon dioxide "coat" on the protein, and the structure of the vaccine remained intact even when heated to 100 degrees C or kept at room temperature for up to three years.
    researchers found that between 3.5 billion and 2.5 billion years ago, the first two metabolic proteins in the evolution of life powered the formation of early life on Earth. The discovery could also act as a chemical signal to help cosmic explorers search for life on other planets.
