Coloured SEM of laser writing on a human hair
Laser script on human hair. Coloured scanning electron micrograph (SEM) of writing on a human hair performed by a medical laser. The German phrase " haargenau und feiner" translates as " Precise as a hair and finer". The flaky scales visible on the hairs surface make up the cuticle, the hairs outermost layer. Lasers are used in medicine for a variety of purposes. In surgery, they are used because of their ability to be directed very accurately at a site which may be inaccessible to normal surgery. Their intense heat is used to burn away or cut tissue. Magnification: x150 at 5x7cm size

Cuticle Hair Laser Lasers Writing Health Care
EDITORS COMMENTS
This print showcases a coloured scanning electron micrograph (SEM) of laser writing on a human hair. The intricate laser script, performed by a medical laser, is beautifully displayed on the hair's surface. The German phrase "haargenau und feiner" meaning "Precise as a hair and finer" adds an artistic touch to this scientific marvel. The flaky scales visible on the hair's outermost layer, known as the cuticle, provide texture and depth to the image. It serves as a reminder of the complexity and delicate nature of our own bodies. Lasers have become invaluable tools in medicine for their remarkable precision. In surgical procedures, they offer unparalleled accuracy when accessing hard-to-reach areas that traditional surgery may struggle with. Their intense heat can be harnessed to either burn away or precisely cut tissue. At a magnification of x150 and printed at 5x7cm size, this print captures every minute detail with stunning clarity. Its vibrant colours and intricate patterns make it both visually striking and scientifically intriguing. Science Photo Library presents this extraordinary image that combines artistry with cutting-edge technology. It serves as a testament to humanity's continuous exploration of innovative techniques in healthcare while highlighting the beauty found even in microscopic realms.
