“…Recently, a new design approach was proposed to increase the mechanical properties of agar/poly (acrylic acid)/hydroxyethyl cellulose (composite) hydrogels prepared by a one-pot method [103]. The insertion of the polyhydroxy compounds allows the formation of a (physically linked) double network (DN), by exploiting the inter-polymers hydrogen bonding interaction [103]. The resulting hydrogels evidenced optimal performances for potential application in biomedical fields [103].…”

The resulting hydrogels evidenced optimal performances for potential application in biomedical fields [103]. Furthermore, a chitosan-graft-poly(ε-caprolactone) (CS-g-PCL) copolymer was studied (in hydrated and dry state) [104] and its performances was compared to those of the individual homopolymers, poly(ε-caprolactone) (PCL) and chitosan (CS) [104].…”

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

The possibilities of thermal imaging and spectral technology in organization of the control of laser technological processes of high-temperature modification of structural materials are analyzed. It is shown that the application of thermal imaging technology is reasonable when adjusting these processes. For continuous control it is more perspective to apply small spectral technique. Solutions are proposed that allow continuous monitoring on the basis of determination of two parameters: the effective heating temperature Te of the treated surface in the area of influence of laser radiation and parameter a associated with the effective heating area. It is shown that introduction of small-sized spectral devices for continuous monitoring into the feedback loop of the control system for laser set-ups is promising.
