“…Novel advanced nanostructured materials, particularly aerogel-based materials, are promising candidates to master these challenges and to circumvent the said limitations [15,16]. The relevance of aerogels can be ascertained by recent review articles [15,16,17,18,19,20,21,22,23,24,25] and two editorial projects [26,27], which summarize already extensive experimental data from research results and their analysis. Based on the most recent advances and uses in aerogel technologies, the anticipated future trends in aerogels applied to biomedical and environmental applications are presented in this opinion paper.…”

Aerogels are a special class of nanostructured materials with very high porosity and tunable physicochemical properties. Although a few types of aerogels have already reached the market in construction materials, textiles and aerospace engineering, the full potential of aerogels is still to be assessed for other technology sectors. Based on current efforts to address the material supply chain by a circular economy approach and longevity as well as quality of life with biotechnological methods, environmental and life science applications are two emerging market opportunities where the use of aerogels needs to be further explored and evaluated in a multidisciplinary approach. In this opinion paper, the relevance of the topic is put into context and the corresponding current research efforts on aerogel technology are outlined. Furthermore, key challenges to be solved in order to create materials by design, reproducible process technology and society-centered solutions specifically for the two abovementioned technology sectors are analyzed. Overall, advances in aerogel technology can yield innovative and integrated solutions for environmental and life sciences which in turn can help improve both the welfare of population and to move towards cleaner and smarter supply chain solutions.

“…Separately, carbon-based organic aerogels have also been synthesized using the sol-gel process. In the late 1980s, Pekala invented the first coal aerogel via resorcinol-formaldehyde-based pyrolysis [47][48][49]. In addition to the resorcinol-formaldehyde-based amorphous coal aerogel, other carbon allotropic aerogels, such as carbon nanotubes and graphene, have also been synthesized; the latter have shown specific surface area values of 500 and 1000 m 2 g À1 , respectively.…”

“…Aerogels are nanostructured, lightweight materials with open, high porosities and large surface areas that currently find applications in many industrial sectors due to their thermal, optical, electrical, or mechanical properties [1,2]. The outstanding textural properties of the aerogels have also attracted the attention from other fields such as biomedical and environmental sciences [3][4][5][6]. Biomedical applications of aerogels include the encapsulation of bioactive agents with solubility or stability limitations, and their use as synthetic scaffolds for tissue engineering and wound dressing materials for chronic wounds [7][8][9][10][11][12][13][14][15][16].…”

Biopolymer-based aerogels can be obtained by supercritical drying of wet gels and endowed with outstanding properties for biomedical applications. Namely, polysaccharide-based aerogels in the form of microparticles are of special interest for wound treatment and can also be loaded with bioactive agents to improve the healing process. However, the production of the precursor gel may be limited by the viscosity of the polysaccharide initial solution. The jet cutting technique is regarded as a suitable processing technique to overcome this problem. In this work, the technological combination of jet cutting and supercritical drying of gels was assessed to produce chitosan aerogel microparticles loaded with vancomycin HCl (antimicrobial agent) for wound healing purposes. The resulting aerogel formulation was evaluated in terms of morphology, textural properties, drug loading, and release profile. Aerogels were also tested for wound application in terms of exudate sorption capacity, antimicrobial activity, hemocompatibility, and cytocompatibility. Overall, the microparticles had excellent textural properties, absorbed high amounts of exudate, and controlled the release of vancomycin HCl, providing sustained antimicrobial activity.
