New archetypes in self-assembled Phe-Phe motif induced nanostructures from nucleoside conjugated-diphenylalanines
During the last two decades, the molecular self-assembly of the short peptide diphenylalanine (Phe-Phe) motif has attracted increasing focus due to its unique morphological structure and utility for potential applications in biomaterial chemistry, sensors and bioelectronics. Due to the ease of their synthetic modifications and a plethora of available experimental tools, the self-assembly of free and protected diphenylalanine scaffolds (H-Phe-Phe-OH, Boc-Phe-Phe-OH and Boc-Phe-Phe-OMe) has unfurled interesting tubular, vesicular or fibrillar morphologies. Developing on this theme, here we attempt to examine the effect of structure and properties (hydrophobic and H-bonding) modifying the functional C-terminus conjugated substituents on Boc-Phe-Phe on its self-assembly process. The consequent self-sorting due to H-bonding, van der Waals force and π-π interactions, generates monodisperse nano-vesicles from these peptides characterized via their SEM, HRTEM, AFM pictures and DLS experiments. The stability of these vesicles to different external stimuli such as pH and temperature, encapsulation of fluorescent probes inside the vesicles and their release by external trigger are reported. The results point to a new direction in the study and applications of the Phe-Phe motif to rationally engineer new functional nano-architectures.
Peptide-Based Molecularly Imprinted Polymer: A Visual and Digital Platform for Specific Recognition and Detection of Ethyl Carbamate
A visual and digital platform was constructed by peptide-based molecularly imprinted polymers (PMIPs) for specific recognition and detection of ethyl carbamate (EC). Here, the optosensing core was creatively constructed by the covalent assembly of dipeptides (H-Phe-Phe-OH) and genipin biomolecules for high fluorescence quantum yield and dual-signal response capability. MIPs were wrapped in the shell of the optosensing core for selectivity of EC from actual samples of alcoholic beverages. The genipin-FF nanoparticles (GFPNs)@PMIPs exhibited dual-band red-blue fluorescence image with a low detection limit of 0.817 and 1.65 μg L-1, respectively, in the optimal linear range of 2-240 μg L-1. The accuracy of this method was verified by the spiked recovery experiment, and a good recovery from 83.97 to 106.75% of the proposed optosensing method was obtained. In addition, a smartphone application was coupled with GFPNs@PMIPs to realize online real-time detection of EC. With the addition of EC, the color change of G and B values was negligible compared with the R value. This work also provides a potential method for on-site visual detection of analytes.
