Abstract
We utilized molecular dynamics (MD) simulations and Molecular Mechanics Poisson-Boltzmann Surface Area (MMPBSA) free energy calculations to investigate the specificity of two oligonucleotide probes, namely probe B and probe D, in detecting single-stranded DNA (ssDNA) within three bacteria families: Enterobacteriaceae, Pasteurellaceae, and Vibrionaceae. Due to the limited understanding of molecular mechanisms in the previous research, we have extended the discussion to focus specifically on investigating the binding process of bacteria-probe DNA duplexes, with an emphasis on analyzing the binding free energy. The role of electrostatic contributions in the specificity between the oligonucleotide probes and the bacterial ssDNAs was investigated and found to be crucial. Our calculations yielded results that were highly consistent with the experimental data. Through our study, we have successfully exhibited the benefits of utilizing in-silico approaches as a powerful virtual-screening tool, particularly in research areas that demand a thorough comprehension of molecular interactions.

Abstract
The Molecular Mechanics Poisson-Boltzmann Surface Area (MMPBSA) approach has been widely applied as an efficient and reliable free energy simulation method to model molecular recognition, such as for protein-ligand binding interactions. In this review, we focus on recent developments and applications of the MMPBSA method. The methodology review covers solvation terms, the entropy term, extensions to membrane proteins and high-speed screening, and new automation toolkits. Recent applications in various important biomedical and chemical fields are also reviewed. We conclude with a few future directions aimed at making MMPBSA a more robust and efficient method.

Abstract
A facile, one-pot synthetic method has been proposed to prepare water-soluble fluorescent copper nanoclusters (CuNCs) templated by nucleosides. The nucleoside-templated fluorescent CuNCs were further characterized by using various analytical techniques, such as transmission electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and fluorescence spectroscopy. The role of various reactants such as ascorbic acid, nucleoside, and citrate buffer in the synthesis process of fluorescent CuNCs was explored. The results showed that nucleoside and ascorbic acid were very likey to respectively act as a stabilizer and a reductant to form nanoclusters, and citrate buffer acted as both pH regulator solution and a reducing agent. The fluorescence spectra of various nucleoside-templated CuNCs were finally combined with multivariate chemometrics analysis for discrimination of different nucleosides.
