“…This material was able to adsorb more than 99.9% of the live bacteria from a bacterial suspension [220]. Uymin et al have prepared a nanocellulose derivate aerogel with a bacterial inhibition rate of >99.99% by loading lysozymes and silver nanoparticles on the surface of a cationic CNF aerogel [221].…”

Due to its excellent performance, aerogel is considered to be an especially promising new material. Cellulose is a renewable and biodegradable natural polymer. Aerogel prepared using cellulose has the renewability, biocompatibility, and biodegradability of cellulose, while also having other advantages, such as low density, high porosity, and a large specific surface area. Thus, it can be applied for many purposes in the areas of adsorption and oil/water separation, thermal insulation, and biomedical applications, as well as many other fields. There are three types of cellulose aerogels: natural cellulose aerogels (nanocellulose aerogels and bacterial cellulose aerogels), regenerated cellulose aerogels, and aerogels made from cellulose derivatives. In this paper, more than 200 articles were reviewed to summarize the properties of these three types of cellulose aerogels, as well as the technologies used in their preparation, such as the sol-gel process and gel drying. In addition, the applications of different types of cellulose aerogels were also introduced.

“…The hydrophilicity of natural polymers can be altered using chemical compounds [ 88 ]. The use of biopolymers as a carrier for different antibacterial substances including antibiotics [ 57 ], essential oils [ 89 ], plant extracts [ 90 ], enzymes [ 91 ], metallic oxides [ 92 ] and nanoparticles has been done [ 93 ]. Figure 5 presents a summary of the preparation process of antibacterial aerogel.…”

“…The prepared aerogel exhibited good absorption capacity, good antibacterial activity, and sustained-release property. In another study, Khan et al [ 91 ] used cellulose nanofibrils as aerogel matrix to immobilize silver nanoparticles and enzymes for antibacterial application. The authors tested their aerogel for potential use in clinical trials and it seemed to be non-toxic and biocompatible.…”

A biopolymer-based aerogel has been developed to become one of the most potentially utilized materials in different biomedical applications. The biopolymer-based aerogel has unique physical, chemical, and mechanical properties and these properties are used in tissue engineering, biosensing, diagnostic, medical implant and drug delivery applications. Biocompatible and non-toxic biopolymers such as chitosan, cellulose and alginates have been used to deliver antibiotics, plants extract, essential oils and metallic nanoparticles. Antibacterial aerogels have been used in superficial and chronic wound healing as dressing sheets. This review critically analyses the utilization of biopolymer-based aerogels in antibacterial delivery. The analysis shows the relationship between their properties and their applications in the wound healing process. Furthermore, highlights of the potentials, challenges and proposition of the application of biopolymer-based aerogels is explored.

“…Use of natural extracts together with cellulose-based aerogel is preferable in medical applications to avoid synthetic and chemical ingredients. In another study, Khan et al 65 used silver nanoparticles and enzymes as antibacterial materials and immobilized these materials inside CNF aerogels. The authors evaluated their aerogel composites for their potential use in clinical trials.…”

Aerogels have been steadily developed since its first invention to become one of the most promising materials for various medical and non-medical applications. It has been prepared from organic and inorganic materials, in pure forms or composites. Cellulose-based aerogels are considered one of the promising materials in biomedical applications due to their availability, degradability, biocompatibility and non-cytotoxicity compared to conventional silica or metal-based aerogels. The unique properties of such materials permit their utilization in drug delivery, biosensing, tissue engineering scaffolds, and wound dressing. This review presents a summary of aerogel development as well as the properties and applications of aerogels. Herein, we further discuss the recent works pertaining to utilization of cellulose-based aerogels for antibacterial delivery.
