Накратко на български

Полимерни структури на нанониво, подобни на „клетки“, се разработват за избирателно улавяне и освобождаване на вещества, като например замърсители във водата. Това помага за подобряване на пречистването на течности, доставката на лекарства и откриването на специфични частици в разтвори.

Polymeric Self-Assembling Units for a Controlled Adsorption and Release at the Nanoscale

Selective adsorption and release is an extremely complex topic with a plethora of possible applications. Drug delivery, designing systems able to monitor and track the presence of given substances in gas or in solutions, selective removal of contaminants from solutions (e.g. heavy metals of antibiotics from water), or systems able to selectively release substances with a controlled release path are all different aspects of the same general class of problem: tunable adsorption and release at the nanoscale. NANODRIVE focuses on the design of functionalisable materials at the nano-scale. In particular NANODRIVE aims at designing macromolecules able to selectively adsorb cargo in crowded solutions, being able to distinguish between different substances in solution and only adsorbing the target ones. Starting from the macromolecular scale, NANODRIVE aims at underpinning the key parameters able to lead to the aimed specific adsorption/release properties. Polymer science has appeared to be a very promising field in the design and realisation of functionalised macromolecules, opening to countless possibilities to design and manufacture building blocks that, by means of a specific architecture or chemical composition, present tunable and controllable properties both at the single molecule level as well as at the mesoscale. NANODRIVE focused on understanding how to exploit the flexibility and tunability of both polymeric systems of different chemical or topological architecture and nanocomposites, to selectively adsorb and release material in solution. In particular, it allowed to design “macromolecules cages” able to recognise and insulate specific target cargos in solutions - e.g. pollutants in water - and to be then able to absorb and release them in a controlled way by tuning a few chemical/physical parameters. The project addressed such a problem from various perspectives at the nanoscale, both designing “smart” polymeric systems as well as exploiting properties of targeted nanocomposites. NANODRIVE allowed to design macromolecules that were able to selectively capture specific target contaminants in solution. In particular two different systems able to selectively remove different heavy metals from aqueous solutions have been designed theoretically and realised experimentally.

Цел на проекта

Creating novel building blocks, which allow for an easy and large-scale fabrication of complex materials, is a challenge and a central goal of diverse scientific fields, ranging from Physics to Materials Science. In recent publications, I introduced di-block copolymer stars (or telechelic star polymers - TSPs) as novel self-assembling building blocks (“soft legos”), made of a soft core, decorated by a tunable number of functionalized regions or patches.TSPs have a robust and flexible architecture and they possess the ability to self-assemble at different levels. At the single-molecule level, they first order as soft patchy colloids which serve then as “soft Lego” for the emergence of larger structures. At the supramolecular level of self-assembly, the soft colloids form complex crystal structures, such as for example diamond or cubic phases.In this project I propose to investigate how such a novel class of highly versatile tunable building blocks can be applied to the self-assembly of novel and designable soft-materials and how to exploit their self- assembly properties for a controlled adsorption and release of nanomaterial into functionalised predetermined regions.IIn contrast to many functionalised building blocks, telechelic star polymers particles are soft and they self-assemble into patchy structures, without the need for cumbersome synthesis techniques. The quantitative multiscale approach that will be used to carry out the theoretical part of this project, will allow a direct mapping to an experimental realization of the system.The objective of this proposal is to investigate how to induce and control a tunable adsorption of nanomaterial within the intramolecular TSP’s self-assembling process, and to use such particles to perform controllable delivery of nanomaterial into target functionalised regions.
