TL;DR: This approach opens a new window for exploring Ln-MOF materials in technological applications, such as optical devices (e.g., lab-on-a-chip), as proof of authenticity for official documents.

TL;DR: Results showed correct classification rates for genuine and false samples over 98.6% and 93.1%, respectively, indicating that the method can be helpful for the forensic analysis of whisky samples.

TL;DR: The application partial least squares for discriminant analysis (PLS-DA) and visible spectrometer measurements obtained by the Video Spectral Comparator (VSC6000®) for the nondestructive identification of blue pen inks of different types and brands in cursive handwriting texts for forensic applications is proposed.

TL;DR: This study classified the 3D metal-organic framework [Eu(BTC)] in a less toxic Globally Harmonized System category ( category 5), with a LD50 (lethal dose) of 5000 mg/kg, ensuring a wide security range for its application.

TL;DR: Results indicate that the developed method is able to discriminate between cocaine hydrochloride and free base samples, to quantify cocaine content as well as to estimate the concentration of main adulterants phenacetin, benzocaine, caffeine, lidocaine and aminopyrine.
