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.
