“…LIBS has also been tested in a variety of other forensic investigations, including document discrimination [88,209,210], fraud detection of a variety of industrial products [211], soil fingerprinting [212,213], and the study of human remains [214,215] or of samples taken from suspects [216]. The success of all these applications heavily relies on the performance of the multivariate chemometric methods used.…”

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.

“…Marín-Roldan et al 107 analisaram tecidos e músculos humanos para discriminar indivíduos post-mortem, bem como o intervalo post--mortem dos mesmos em cenas de crimes e desastres naturais. E em outra abordagem, a partir de fragmentos de dentes e ossos humanos, Moncayo et al 259 desenvolveram um método analítico simples, rápido e não destrutivo, combinando LIBS e quimiometria para discriminar e classificar restos cadavéricos de vítimas de desastres.…”

This review attempts to present a broad view of the technique laser-induced breakdown spectroscopy (LIBS), since its origin, fundamentals, sample preparation strategies, use of chemometric tools for data processing, the advantages and limitations with regard to qualitative and quantitative analysis, aplications and future trends as an analytical technique that is in consolidation in analytical chemistry. LIBS is a rapid and versatile, which is able 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 enables remote analysis. The advancement of the LIBS applications in the areas of agriculture, environmental, food, biological/pharmaceutical, forensic, metallurgy and electronic waste were discussed in detail in this review. We consider that this review will be an important tool concerning dissemination of the LIBS, mainly for audience of undergraduate courses, and disciplines related to instrumental analysis.

“…The LIBS technique and the methodology used in the present work together with the most significant experimental conditions have been previously described [33]. Briefly, LIBS analysis were carried out using a Q-switched Nd:YAG laser (Quantel, Brio model) operating at 1064 nm and generating 4 ns (FWHM) pulses with 100 mJ, 4 mm beam diameter and 0.6 mrad divergence.…”
