Special Issue Information

Dear Colleagues,

This Special Issue aims to provide an overview of the developments in a variety of self-assembled nanomaterials that combine both organic and inorganic elements. With the rapid development of nanotechnology, great advancements have been witnessed in chemical self-assembly, in which a series of elegant, complex, and adaptable hierarchical structures have been successfully constructed. With the help of assembly technology, these intriguing and exotic chemical, photophysical, and anisotropic mass transport features of nanocomponents were integrated into robust macroscale materials or devices with unprecedented and attractive functionalities.

 Although remarkable achievements have been made in the field of self-assembled nanomaterials over the past few decades, several major challenges still exist for further development in terms of nanomaterials’ alignment, dynamic mechanism revelation, the discovery of novel properties, and performance optimization. For instance, the questions of how to develop novel assembly strategies to integrate nano-building blocks into macroscale structures with high precision and large scale and how to forecast, regulate, and optimize the properties of nanomaterials-based assemblies remain. In the future, extensive investigation, comprehension, and novel manufacturing protocols for self-assembled nanomaterials are thus required.

A taste sensor with global selectivity can be used to discriminate taste of foods and provide evaluations. Interfaces that could interact with broad food ingredients are beneficial for data collection. Here, we prepared electrochemically reduced graphene oxide (ERGO)-modified interdigital electrodes. The interfaces of modified electrodes showed good sensitivity towards cooking condiments in mixed multi-ingredients solutions under electrochemical impedance spectroscopy (EIS). A database of EIS of cooking condiments was established. Based on the principal component analysis (PCA), subsets of three taste dimensions were classified, which could distinguish an unknown dish from a standard dish. Further, we demonstrated the effectiveness of the electrodes on a typical dish of scrambled eggs with tomato. Our kind of electronic tongue did not measure the quantitation of each ingredient, instead relying on the database and classification algorithm. This method is facile and offers a universal approach to simultaneously identifying multiple ingredients. Full article
