Study Notes
Aseptic Technique
- The main function of aseptic technique is to prevent contamination of sterile equipment, surfaces, and specimens with microorganisms.
Microscope Calibration
- A stage micrometer helps in calibrating microscopes by providing a precise measurement of the microscopic field, allowing for accurate calculation of magnification and measurement of microscopic objects.
Hand Soaps
- The primary action of hand soaps in limiting the spread of pathogens is to break down the outer membrane of microorganisms, rendering them inactive.
Sanitizers
- Sanitizers primarily act against pathogens by denaturing proteins, disrupting cell membranes, and interfering with cellular metabolism.
Soap Molecules
- The structure of soap molecules, which consists of a hydrophobic tail and a hydrophilic head, enables them to remove dirt and microbes by emulsifying oils, solubilizing dirt, and allowing for the removal of microbes from the skin.
