Summary: Switchable inversion of chirality between opposite handedness by varying pH is found in a histidine pendant polymer, PBHis. This phenomenon is demonstrated by circular dichroism and fluorescence correlation spectroscopy, which measure the changes of hydrodynamic radius at the single molecular level. Below pH 8.0, the polyelectrolyte adopts M-helicity, while above pH 8.0, it changes into P-helicity. Above pH 10.6, the helicity further inverses into M-chirality. The protonation and deprotonation of the imidazole group, as well as the hydroxide-ion-mediated hydrogen bonding, determine the mutual orientation and handedness of the helical structure.

It was successfully applied for non-contact and visual evaluating and monitoring VBNs in shrimp samples.

Summary: A novel strategy combining a pH-responded colourimetric sensor array (CSA) with machine learning models was developed to effectively monitor beef freshness in real time by detecting total volatile basic nitrogen (TVB-N) contents. Sequential forward selection (SFS), random forest (RF), and principal component analysis (PCA) were used to extract effective colour features sensitive to changes in TVB-N contents. Linear regression (PLSR), as well as nonlinear regression models (RFR and SVR), were established to predict TVB-N values based on full and effective colour features. The RF-SVR model showed the best performance, with a determination coefficient of prediction (Rp2) of 0.9596, a root-mean-square error of prediction (RMSEP) of 1.89 mg/100 g, and a relative prediction deviation (RPD) of 4.98. The CSA based on the RF-SVR model was applied to quantify beef freshness at 4 degrees with validation using a standard method. This study demonstrated that the CSA, combined with machine learning, can objectively and nondestructively monitor TVB-N contents for evaluating beef freshness.
