We report on the fabrication of shellac thin films on silicon substrates by matrix-assisted pulsed laser evaporation (MAPLE) using methanol as matrix. Very adherent, dense, and smooth films were obtained by MAPLE with optimized deposition parameters, such... see more

Background: Streptococcus mutans (S. mutans) bacteria mainly cause dental caries in children. These bacteria are not considered oral indigenous bacteria since they are transmitted from people around children during their deciduous teeth eruption. The dete... see more

Staphylococcal species, notably, coagulase negative staphylococci (CoNS), are considered important causative agents of health-care associated infections (HAI) associated with catheters and implanted medical devices. The increasing incidence of CoNS in HAI... see more

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has been used in clinical diagnostic laboratories for the identification of microorganisms. It has a relevant advantage compared to other methods in terms of speed... see more

Introduction: Identification of yeast species has clinical and epidemiological value. Different methods can be used, such as chromogenic media, microculture on corn meal agar with Tween 80, as well as conventional biochemical and automated methods. Recent... see more

This is a report of isolation of Cryptococcus neoformans from blood culture. Identification was conducted by matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry. The relevance of this report is related to the site affected, the se... see more

Report of Chromobacterium violaceum isolation from blood culture. Identification by MALDI-TOF mass spectrometry. Relevant report due to the site affected, infection severity, and importance of correct and rapid identification for a successf... see more

Analysis of impurity in powder samples has been made by using metal-assisted laser-induced plasma spectroscopy utilizing a pulsed CO2 laser. Various powders including food powder, supplement powder, baby powder, and medicine powder were employed as sample... see more
