“…Indeed, these techniques use different concentrations of the polymeric dispersion that give rise to nanofibers by electrospinning with high concentrations of the polymer or fine droplets/particles when a low polymer concentration is used in the electro-spraying [ 54 ]. Since these methodologies do not require heating treatments, they are very promising for the encapsulation of heat-sensitive compounds such as flavours, fragrances and EOs [ 55 , 56 , 57 ]. Different polymers have been evaluated for the formation of nanofibers encapsulating volatile compounds, such as cellulose derivatives [ 58 ], biodegradable polyesters [ 59 ], dendrimers [ 60 ] or polysaccharides such as seed gums and mucilages [ 61 , 62 ].…”

Flavours and fragrances are volatile compounds of large interest for different applications. Due to their high tendency of evaporation and, in most cases, poor chemical stability, these compounds need to be encapsulated for handling and industrial processing. Encapsulation, indeed, resulted in being effective at overcoming the main concerns related to volatile compound manipulation, and several industrial products contain flavours and fragrances in an encapsulated form for the final usage of customers. Although several organic or inorganic materials have been investigated for the production of coated micro- or nanosystems intended for the encapsulation of fragrances and flavours, polymeric coating, leading to the formation of micro- or nanocapsules with a core-shell architecture, as well as a molecular inclusion complexation with cyclodextrins, are still the most used. The present review aims to summarise the recent literature about the encapsulation of fragrances and flavours into polymeric micro- or nanocapsules or inclusion complexes with cyclodextrins, with a focus on methods for micro/nanoencapsulation and applications in the different technological fields, including the textile, cosmetic, food and paper industries.

“…In particular, the solvent properties and the collector geometry seem to influence the porosity of the electrospun fibers. Indeed, the volatility of the solvent can affect the fiber surface, and the boiling point of the solvents and nonsolvents used can create pores due to the phase separation phenomena that occur before or during the electrospinning process [107]. Chitosan, alginate, and cellulose are the most common polysaccharide-based biopolymers used for wound dressings [108].…”

Wound healing refers to the replacement of damaged tissue through strongly coordinated cellular events. The patient’s condition and different types of wounds complicate the already intricate healing process. Conventional wound dressing materials seem to be insufficient to facilitate and support this mechanism. Nanotechnology could provide the physicochemical properties and specific biological responses needed to promote the healing process. For nanoparticulate dressing design, growing interest has focused on natural biopolymers due to their biocompatibility and good adaptability to technological needs. Polysaccharides are the most common natural biopolymers used for wound-healing materials. In particular, alginate and chitosan polymers exhibit intrinsic antibacterial and anti-inflammatory effects, useful for guaranteeing efficient treatment. Recent studies highlight that several natural plant-derived molecules can influence healing stages. In particular, essential oils show excellent antibacterial, antifungal, antioxidant, and anti-inflammatory properties that can be amplified by combining them with nanotechnological strategies. This review summarizes recent studies concerning essential oils as active secondary compounds in polysaccharide-based wound dressings.

“…Additionally, these studies underlined the preservation of the bioactivity of EOs after mixing with various polymer systems and processing by electrospinning. Moreover, the EOs released from the products obtained through the electrospinning process still presented the characteristics of the inserted EOs, namely antimicrobial, anti-inflammatory, and antioxidant activity [ 88 ].…”

The article reviews the possibilities of encapsulating essential oils EOs, due to their multiple benefits, controlled release, and in order to protect them from environmental conditions. Thus, we present the natural polymers and the synthetic macromolecular chains that are commonly used as networks for embedding EOs, owing to their biodegradability and biocompatibility, interdependent encapsulation methods, and potential applicability of bioactive blend structures. The possibilities of using artificial intelligence to evaluate the bioactivity of EOs—in direct correlation with their chemical constitutions and structures, in order to avoid complex laboratory analyses, to save money and time, and to enhance the final consistency of the products—are also presented.
