Johnstone, B.Sc, Ph.D, M.B, Ch.Bb(Leeds) F.R.M.S., A.R.P.S. he was known for his contributions to microbiology and specifically for his work on micromanipulation techniques involving bacteria. His book titled "Micromanipulation of Bacteria" is an authoritative resource in this specialized area of research. In this book, Johnstone discusses various techniques for manipulating microscopic organisms, including the use of a microforge.A microforge is a precision instrument used in biological laboratories to modify microtools under a microscope. It typically involves a heating element to melt and shape glass needles or other microtools, which can be used for handling microscopic samples such as single cells or bacteria.Johnstone's work and his book are significant because they provide detailed methodologies for researchers working with microorganisms, offering insights into handling, manipulating, and modifying microscopic life forms for experimental purposes. This has applications in various fields, including microbiology, cellular biology, and medical research.
