A simple device based on two commercial laser pointers is described to assist in the analysis of samples that present uneven surfaces and/or irregular shapes using laser-induced breakdown spectroscopy (LIBS). The device allows for easy positioning of the sample surface at a reproducible distance from the focusing lens that conveys the laser pulse to generate the micro-plasma in a LIBS system, with reproducibility better than ±0.2 mm. In this way, fluctuations in the fluence (J cm) are minimized and the LIBS analytical signals can be obtained with a better precision even when samples with irregular surfaces are probed.

African swine fever (ASF) is an acute hemorrhagic disease in pigs caused by the African swine fever virus (ASFV), which has a high mortality rate and brought great damage to global pig farming industry. At present, there is no effective treatment or vaccine to combat ASFV infection, so early detection of ASFV has become particularly important. Therefore, the PDMS/chitosan/MPMs composite film was proposed to detect ASFV P72.

Cellulose nanofibers (CNFs) have gained increasing attention due to their robust mechanical properties, favorable biocompatibility, and facile surface modification. However, green and recyclable CNF production remains challenging. Herein, a green, low-cost and room-temperature strategy was developed to exfoliate CNFs using deep eutectic solvents.
