After entering the body, nanoparticles can reach the organs through systemic circulation. Furthermore, depending on their characteristics, such as size, shape, and chemical reactivity, they can cross the blood-brain barrier, or they can reach the brain through axonal transport along the olfactory nerve
Patiently waiting for the storm. Love my country. OMG Podesta in the news again, let’s goooo!
yes and nanobots. i would like some sort of face shield that would emit neg ions to disarm them if thats possible.
In an atom, a positive charge occurs when an atom has more protons than electrons. The proton is what determines its positive charge. It is denoted with a plus (+) sign. It attracts negative charges and repels other positive charges.
This difference in charge is called the cell's membrane potential. In the process of depolarization, the negative internal charge of the cell temporarily becomes more positive (less negative). This shift from a negative to a more positive membrane potential occurs during several processes, including an action potential. During an action potential, the depolarization is so large that the potential difference across the cell membrane briefly reverses polarity, with the inside of the cell becoming positively charged.
Cell polarity refers to the intrinsic asymmetry observed in cells, either in their shape, structure, or organization of cellular components. Most epithelial cells, migrating cells and developing cells require some form of cell polarity for their function.
What is meant by cell polarity?
Cell polarization, defined as the asymmetric distribution of proteins, organelles, and cytoplasm, occurs in many forms (1). The most commonly known is the apical-basal polarity of epithelial cells.1 Jan 2019
