Published: Nov. 15, 2019

Abstract This Review presents polysaccharides, oligosaccharides, nucleic acids, peptides, and proteins as functional stimuli‐responsive polymer scaffolds that yield hydrogels with controlled stiffness. Different physical or chemical triggers can be used to structurally reconfigure the crosslinking units control stiffness of hydrogels. The integration supramolecular complexes biomolecular crosslinkers leads hybrid undergoing reversible triggered transitions across different states. applications biomolecule‐based are discussed. assembly hydrogel films on surfaces their coating drug‐loaded nanoparticles for drug release is also presented.

Self-Assembly of Organic Nanomaterials and Biomaterials: The Bottom-Up Approach for Functional Nanostructures Formation and Advanced Applications

Materials, Journal Year: 2020, Volume and Issue: 13(5), P. 1048 - 1048

Published: Feb. 26, 2020

In this paper, we survey recent advances in the self-assembly processes of novel functional platforms for nanomaterials and biomaterials applications. We provide an organized overview, by analyzing main factors that influence formation organic nanostructured systems, while putting into evidence challenges, limitations emerging approaches various fields nanotechology biotechnology. outline how building blocks properties, mutual cooperative interactions, as well initial spatial configuration (and environment conditions) play a fundamental role construction efficient materials with desired properties. The insertion endgroups (such polymers, peptides or DNA) within units has enormously increased complexity morphologies functions can be designed fabrication bio-inspired capable mimicking biological activity. However, unwanted uncontrollable effects originating from unexpected thermodynamic perturbations complex interactions interfere at molecular level assembly process. Correction harmonization is one major challenges next decades requires deeper knowledge understanding key drive nanomaterials. Self-assembly still remains central topic current research located interface between material science engineering, biotechnology nanomedicine, it will continue to stimulate renewed interest biologist, physicists engineers combining principles concept supramolecular chemistry.
