Laser-induced breakdown spectroscopy (LIBS) has become an established analytical atomic spectrometry technique and is valued for its very compelling set of advantageous analytical and technical characteristics. It is a rapid, versatile, non-contact technique, which is capable of providing qualitative and quantitative analytical information for practically any sample, in a virtually non-destructive way, without any substantial sample preparation. The instrumentation is simple, robust, compact, and even enables remote analysis. This review attempts to give a critical overview of the diverse progress of the field, focusing on the results of the last five years. The advancement of LIBS instrumentation and data evaluation is discussed in detail and selected results of some prominent applications are also described.

“…Zheng et al 62 have recently used LIBS to characterize animal tissues. Recently, Emara et al 63 64 performed non-invasive, in-situ detection of malignant skin tissue and other abnormalities using a portable LIBS system with a fibre spectrometer and an eye-safe erbium glass laser. They established a medical screening procedure that used a compact "eyesafe" LIBS device capable of real-time, in-situ determination of healthy and unhealthy skin tissue without performing traditional biopsy.…”

Applications of laser-induced breakdown spectroscopy (LIBS) are growing rapidly and continue to extend its horizon to include a broad variety of materials. The recent progress made in the field has transformed LIBS from being an elemental analysis technique to the one applicable for the analysis of molecularly complex biological samples and specimens. LIBS has thus, proven its capability as detection, characterization and identification tool for studying a range of biological specimens and biomaterials. A review is presented here to discuss recent developments and future potential of LIBS and its viability for possible biomedical applications.

“…Furthermore, there is a lack of information regarding other chemical elements that constitute hair. 14 The use of LIBS for the tests is complementary in the investigation of hair and maintains the integrity of the samples, 19 which, as mentioned above, is a relevant issue.…”

The cosmetic modification of hair is a very common procedure used to mask or cover evidence at a crime scene. Deoxyribonucleic acid (DNA) tests are expensive and require good-quality collection of samples and a database profile. To overcome these challenges, direct analysis was performed on a large set of hair strands collected from individuals, denoted original samples, and the data were compared with those of the same samples after cosmetic modification performed by bleaching the samples in the laboratory. A total of 127 samples were evaluated in this study using two analytical techniques, wavelength-dispersive X-ray fluorescence (WDXRF) and laser-induced breakdown spectroscopy (LIBS). Instead of testing many algorithms to develop classification models for the original and bleached samples, a recent method was applied that combines information from 17 classifiers. Data fusion was also evaluated to improve the accuracy of the classification model, which was higher than 99.2%, with no requirements to select eigenvectors or thresholds.
