“…Besides, angular deformation of N-H (1595 cm -1 ), symmetrical angular deformation of CH3 (1429 cm -1 ), axial deformation of amide -CN (around 1343 cm -1 ) and axial deformation -CN of amino groups (between 1274 to 1208 cm -1 ), corroborating the peaks found (Novaes et al, 2020). FTIR spectra extract of M. oleifera showed a broadband centered at 3393 cm -1 , attributed to the elongation of OH bands of water adsorbed on the surface of the material and phenol alcohol groups.…”

Moringa oleifera Lam is a plant found in Brazil, with applications in the food, agricultural, industrial, and medicinal areas. M. oleifera has favourable healing properties, and chitosan has healing potential. This polymer is a biocompatible, non-toxic and biodegradable polycationic biopolymer. Chitosan membranes have good mechanical strength and selective molecular permeability. These membranes used in food packaging, artificial skin, wound healing, drug delivery systems and other applications. This study aims to prepare chitosan membranes to incorporate ethanol extract from the seed of M. oleifera for use as a biomaterial. We first describe methods to obtain M. oleifera extract, and second highlight method to prepare membranes. We use Fourier Transform Infrared (FTIR) Spectroscopy to verify the incorporation of extract in the membrane. The results obtained was homogeneous and malleable membranes. The absorption spectrum in the infrared region showed bands characteristic of chemical groups of both chitosan and the incorporated extract. This incorporation can be applied to improve the performance of membranes with chitosan for use as biomaterial, such as wound healing.

“…Most of the literature studies regarding collagen-based silver nanomaterials carried out the maintenance of the nanosized dimension of silver particles, while being mixed in formulations with antibacterial applications [ 18 , 19 , 20 ]. A recent study performed by Novaes et al [ 21 ] revealed that Ag NPs can also be entrapped in blends for a long-lasting release effect. Using a mix of chitosan and collagen in different rations to form blends, the final material achieved open pores with high interconnectivity between them able to encapsulate the Ag NPs.…”

“…After the encapsulation in the blends, the results of TEM microscopy for nanoparticles showed a spherical form and a dimension of 15–35 nm. Since the size of nanoparticles and their antibacterial effect are dependent properties [ 22 ], this method of encapsulation is a promising result in tissue regeneration applications [ 21 ]. Another strategy in composites is based on the development of polymeric hydrogels loaded with silver nanoparticles [ 23 , 24 , 25 ].…”

Silver nanoparticles have been intensively studied over a long period of time because they exhibit antibacterial properties in infection treatments, wound healing, or drug delivery systems. The advantages that silver nanoparticles offer regarding the functionalization confer prolonged stability and make them suitable for biomedical applications. Apart from functionalization, silver nanoparticles exhibit various shapes and sizes depending on the conditions used through their fabrications and depending on their final purpose. This paper presents a review of silver nanoparticles with respect to synthesis procedures, including the polluting green synthesis. Currently, the most commonly used characterization techniques required for nanoparticles investigation in antibacterial treatments are described briefly, since silver nanoparticles possess differences in their structure or morphology.

“…Collagen, as one of the most widely used cosmetic ingredients with moisturizing and anti-aging properties, would be a desirable polymer to be combined with chitosan. Chitosan/collagen blends are the subjects of many studies, mainly in the tissue-engineering field [ 146 , 147 , 148 ]. Sadeghi-Avalshahr et al examined this composition in grafting the surface of the prepared from PCL/PVP electrospun samples.…”

“…The authors indicate this composition as a promising scaffold for skin regeneration [ 149 ]. Blends containing chitosan and collagen are also considered as a bioink for obtaining 3D structures [ 147 ]. A popular solution is also the addition of nanoparticles to such blends to improve antibacterial activity [ 150 ].…”

This review provides a report on the properties and recent advances in the application of chitosan and chitosan-based materials in cosmetics. Chitosan is a polysaccharide that can be obtained from chitin via the deacetylation process. Chitin most commonly is extracted from cell walls in fungi and the exoskeletons of arthropods, such as crustaceans and insects. Chitosan has attracted significant academic interest, as well as the attention of the cosmetic industry, due to its interesting properties, which include being a natural humectant and moisturizer for the skin and a rheology modifier. This review paper covers the structure of chitosan, the sources of chitosan used in the cosmetic industry, and the role played by this polysaccharide in cosmetics. Future aspects regarding applications of chitosan-based materials in cosmetics are also mentioned.
