1. IntroductionBioluminescence, the emission of light by living organisms, is commonly used as a communication mechanism among organisms [1,2], and humans have employed it for bioindication purposes. The firefly luciferin–luciferase system has been extensively used for ATP detection in microbiological contamination assays [3,4]. This system catalyzes light emission through the oxidation of a benzothiazolic luciferin in the presence of ATP and magnesium [4].

We review the recent progress that have led to the development of porous materials based on cellulose nanostructures found in plants and other resources. In light of the properties that emerge from the chemistry, shape and structural control, we discuss some of the most promising uses of a plant-based material, nanocellulose, in regenerative medicine.

Abstract:In the course of SARS-CoV-2 infection, the 3CL or nsp5 protease plays a pivotal role as the most important viral protease required for the maturation of viral proteins during host infection. Herein, we simulated for 500 ns 3CLproWT, 3CLproH41A, 3CLproBeta, and 3CLproOmicron, in complex with the substrates nsp 4|5 and nsp 5|6.
