LIBS Technology in Advanced Cancer Diagnostics


According to the World Health Organization, cancer is the second leading cause of death globally (1). Recent advancements focusing on early detection have fueled growth in the industry which is projected to reach $23 million by the end of 2025 (2).


As the average US age increases, the incidence of cancer also becomes more common. Medical diagnostics tools must continue to innovate in order to reduce the impacts of this deadly disease. Rapid, large-scale cancer screening devices, real-time analysis, and in vivo diagnostics are some technologies founded by modern research. Laser Induced Breakdown Spectroscopy, or LIBS, is another method for detection that has received a great deal of recent attention.


LIBS has been most commonly used in the past for material analysis in applications such as hazardous material detection, soil quality, and food analysis. Yet, new research reveals that this same spectrochemical method can be used to detect the minute differences between normal and cancerous tissue cells.


This article will explore some of the known advantages and drawbacks of LIBS as applied to cancer diagnosis.


Advantages of Laser-Induced Breakdown Spectroscopy

LIBS presents several advantages, most notably, the speed of identification. In less than one second, the spectrochemical analysis is complete with the help of a Nd:YAG laser. According to research published in Cancer Science & Therapy, “A LIBS sys
