Journal ArticleDOI
Sample treatment and preparation for laser-induced breakdown spectroscopy
Sarah C. Jantzi,Vincent Motto-Ros,Florian Trichard,Yuri Markushin,Noureddine Melikechi,Alessandro De Giacomo +5 more
TL;DR: In this paper, the authors highlight the work of many LIBS researchers who have developed, adapted, and improved upon sample preparation techniques for various specimen types in order to improve the quality of the analytical data that LIBS can produce in a large number of research domains.
Journal ArticleDOI
Tag-femtosecond laser-induced breakdown spectroscopy for the sensitive detection of cancer antigen 125 in blood plasma
TL;DR: It is shown that elemental encoded particle assay coupled with femtosecond laser-induced breakdown spectroscopy for simultaneous multi-elemental analysis can significantly improve biomarker detectability and lead to sensitive detection of ovarian cancer biomarker CA125 in human blood plasma.
Journal ArticleDOI
Age-specific discrimination of blood plasma samples of healthy and ovarian cancer prone mice using laser-induced breakdown spectroscopy
Noureddine Melikechi,Yuri Markushin,Denise C. Connolly,Jérémie Lasue,Ebo Ewusi-Annan,Sokratis Makrogiannis +5 more
TL;DR: LIBS and multivariate analysis may be a novel approach for detecting EOC and the results suggest that it is possible to distinguish blood plasma samples obtained from serially bled tumor-bearing TgMISIIR-TAg transgenic and wild type cancer-free littermate control mice.
Journal ArticleDOI
Automatic Classification of Laser-Induced Breakdown Spectroscopy (LIBS) Data of Protein Biomarker Solutions
David D. Pokrajac,Aleksandar Lazarevic,Vojislav Kecman,Aristides Marcano,Yuri Markushin,Tia Vance,Natasa Reljin,Samantha McDaniel,Noureddine Melikechi +8 more
TL;DR: The proposed approach demonstrates that highly accurate automatic classification of complex protein samples from laser-induced breakdown spectroscopy data can be successfully achieved using principal component analysis with a sufficiently large number of extracted features, followed by a wrapper technique to determine the optimal number of principal components.
Proceedings ArticleDOI
Classification of LIBS protein spectra using support vector machines and adaptive local hyperplanes
Tia Vance,Natasa Reljin,Aleksandar Lazarevic,Dragoljub Pokrajac,Vojislav Kecman,Noureddine Melikechi,Aristides Marcano,Yuri Markushin,Samantha McDaniel +8 more
TL;DR: Experiments performed on real life data suggest that both classification methods are quite efficient in distinguishing among four types of proteins and they have a fairly robust detection performance for a range of the numbers of extracted features as well as the algorithms' parameters.
