“…The antimicrobial effect observed for E. coli was greater than for S. aureus . All samples containing CS showed excellent antimicrobial effect [ 106 , 107 , 108 , 109 ]. This study shows, on the one hand, that CS would be effective against more than one type of microorganism, filamentous fungi, as well as bacteria, but in the case of bacteria a greater activity against Gram-negative.…”

The call to use biodegradable, eco-friendly materials is urgent. The use of biopolymers as a replacement for the classic petroleum-based materials is increasing. Chitosan and starch have been widely studied with this purpose: to be part of this replacement. The importance of proper physical characterization of these biopolymers is essential for the intended application. This review focuses on characterizations of chitosan and starch, approximately from 2017 to date, in one of their most-used applications: food packaging for chitosan and as an adsorbent agent of pollutants in aqueous medium for starch.

“…Essential oils (EOs) such as monoterpenes and sesquiterpenes are low-molecularweight secondary metabolites from plants. Because of flavor, aroma, and antimicrobial properties, they are used in various fields such as agriculture [33], medicine [34,35], wound healing [14,36], cosmetics [37,38], pharmaceuticals, tissue engineering to develop skin scaffolds [39][40][41][42][43], and the food packaging industry [44][45][46][47][48][49][50][51]. Depending on the functional groups, the EOs may be more or less hydrophobic in nature, which must be taken into account when incorporating them into a specific polymer matrix.…”

“…Depending on the functional groups, the EOs may be more or less hydrophobic in nature, which must be taken into account when incorporating them into a specific polymer matrix. Successful formulation can be demonstrated by various standard techniques such as FTIR, UV-vis, 1 HNMR, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and X-ray diffraction (XRD) [47,48]. With regard to wound healing and medical applications, secondary compounds have traditionally been used in folk medicine for wound treatment.…”

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.

“…Most of the bioactive plastics come from petroleum‐based polymers, owing to their excellent performances, environmental microbial inertia, easy processability and low cost 18 . However, the growing environmental awareness due to the fast landfill accumulation of post‐used petroleum‐based plastics, and the current reduction of fossil fuel sources, 19 are directing scientists to focus their attention on biodegradable polymer‐based materials as eco‐sustainable alternatives 20 …”

BACKGROUND The organic extracts (OEs) of Dittrichia viscosa, a ruderal plant common in the Mediterranean regions, proved to have herbicidal properties. In order to improve OE effectiveness and to develop novel eco‐friendly bioherbicidal products, different amounts of OE were included in poly(butylene succinate)‐ and polycaprolactone‐based films (PBS and PCL, respectively). Particular attention was given to the study of interactions between the polymers and OEs, with a deep spotlight concerning the influence of OEs on structural, morphological and thermal properties of both polymers, in order to assess the OE releasing kinetics from the matrices and its tuned herbicidal action against seeds. RESULTS The bioassays carried out on Lepidium sativum and Phelipanche ramosa seeds evidenced a more controlled and effective OE release by PBS than PCL, and a longer lasting efficacy by the polymers with a higher OE content. The chemical–physical analyses were performed on films before and after biological assays. The thermogravimetric analysis confirmed that OE was a thermal stabilizer of the polymer; the presence of OE and polymer separated degradative kinetics suggested that only a partial and functional miscibility between polymers and OE occurred. The morphological analysis confirmed the good OE dispersion between PBS and PCL molecular chains. Infrared spectroscopy highlighted the enhanced hydrolysed structure of the doped polymers after the bioassays. These outcomes well matched the quantitative information outlined by release kinetics. DISCUSSION The use of biodegradable polymers allows the effectiveness and tuning of the release of the formulated bioactive compounds to be improved. The easy‐to‐obtain and easy‐to‐formulate OE could become a suitable and environmentally friendly instrument in weed management programmes.
