How the marriage of crystals and lasers is revolutionizing modern medical diagnosis and treatment
In short: Crystals exist in our bones, teeth, and even in diseases like gout. By combining these natural structures with the precision of lasers, scientists are developing groundbreaking medical tools. From painless tissue removal to targeted cancer therapy, this technology is transforming how we understand and treat the human body today.
Crystalline molecular arrangements are fundamental to the human body, appearing naturally in healthy bones, muscles, tendons, and teeth. However, these structures are also linked to various medical conditions, including osteoarthritis, gout, and muscular diseases. A major scientific objective today involves designing and constructing synthetic human bones, particularly for use in hip-replacement surgeries, highlighting the intersection of material science and human health.
The integration of laser technology into medicine has provided unprecedented capabilities. By piping laser light through optical fibres, clinicians can observe internal life processes and treat previously intractable conditions. Infrared lasers are frequently utilized as surgical cutting tools, while ultraviolet lasers have introduced the concept of tissue ablation. This process allows for the removal of surface tissue, such as that found in blood vessels, without generating any heat, offering a painless alternative to traditional methods.
Beyond physical cutting, lasers enable highly selective therapies. Photodynamic therapy (PDT) involves labelling diseased tissue, such as cancerous cells, with specific dyes. Once marked, these cells can be destroyed precisely using red lasers. While crystals have existed on Earth for millions of years, the first laser—built from a man-made ruby crystal—was created less than thirty years prior to the 1987 lectures delivered by John Meurig Thomas and David Phillips. Today, these combined technologies are central to advancements in medicine, environmental science, and energy research.
The 1987 Christmas Lectures at the Royal Institution, filmed on January 2, 1988, explored these themes extensively. Professors Thomas and Phillips examined the history of physical sciences and the evolution of these tools. Their work underscores that crystals and lasers are not merely laboratory curiosities but essential components in the quest to solve complex biological challenges and improve human well-being.
