“…Most researchers conclude that the antimicrobial effect seems to be highest if cationic fragments are closer to the polymer backbone, and it tends to decrease when the functional groups are present at an increasing distance from the polymer chain. This effect is clearly observed when the same functional group is bounded to the polymer by chains of different lengths [ 8 , 62 , 64 ].…”

The biomedical and therapeutic importance of chitosan and chitosan derivatives is the subject of interdisciplinary research. In this analysis, we intended to consolidate some of the recent discoveries regarding the potential of chitosan and its derivatives to be used for biomedical and other purposes. Why chitosan? Because chitosan is a natural biopolymer that can be obtained from one of the most abundant polysaccharides in nature, which is chitin. Compared to other biopolymers, chitosan presents some advantages, such as accessibility, biocompatibility, biodegradability, and no toxicity, expressing significant antibacterial potential. In addition, through chemical processes, a high number of chitosan derivatives can be obtained with many possibilities for use. The presence of several types of functional groups in the structure of the polymer and the fact that it has cationic properties are determinant for the increased reactive properties of chitosan. We analyzed the intrinsic properties of chitosan in relation to its source: the molecular mass, the degree of deacetylation, and polymerization. We also studied the most important extrinsic factors responsible for different properties of chitosan, such as the type of bacteria on which chitosan is active. In addition, some chitosan derivatives obtained by functionalization and some complexes formed by chitosan with various metallic ions were studied. The present research can be extended in order to analyze many other factors than those mentioned. Further in this paper were discussed the most important factors that influence the antibacterial effect of chitosan and its derivatives. The aim was to demonstrate that the bactericidal effect of chitosan depends on a number of very complex factors, their knowledge being essential to explain the role of each of them for the bactericidal activity of this biopolymer.

“…This tendency is a worrying one, which is why research is focused on developing new molecules that are potentially active against these microorganisms and that could be widely used with outstanding antibacterial or antifungal results [6,7]. Over time, various materials with bacteriostatic [8][9][10], bactericidal [11][12][13][14][15], fungistatic [10,16] and fungicidal [11,12,[17][18][19][20] properties, against a wide spectrum of microorganisms, have been studied. It is known that materials with antimicrobial activities are of interest, both for academic studies and for industry.…”

“…Because most antibacterial materials are synthetic polymers [23], their biocompatibility and biodegradability are much more limited than those of natural polymers, such as cellulose, chitin, chitosan and their derivatives [3,12,15,[24][25][26][27][28]. Although chitosan is naturally abundant [8], it is limited in terms of its reactivity and processability, which is why it is functionalized with various active groups, so as to improve its properties [12,21,25,[29][30][31][32][33][34].…”

Considering the challenge created by the development of bacterial and fungal strains resistant to multiple therapeutic variants, new molecules and materials with specific properties against these microorganisms can be synthesized, like those synthesized from biopolymers such as chitosan with improved antimicrobial activities. Antimicrobial activities of seven obtained materials were tested on four reference strains belonging to American Type Culture Collection. The best antimicrobial activity was obtained by functionalization by impregnation of chitosan with quaternary ammonium salts, followed by that obtained by functionalization of chitosan with phosphonium. The lowest antibacterial and antifungal effects were expressed by Ch-THIO and Ch-MBT, but new materials obtained with these extractants may be precursors with a significant role in the direct control of active molecules, such as cell growth factors or cell signaling molecules.

“…[5][6][7] Alg has no intrinsic antimicrobial property. For this reason, antimicrobial agents such as silver nanoparticles, 8,9 essential oils, [10][11][12] conventional antibiotics, 13,14 and polypeptides 15,16 are physically or chemically incorporated to Alg chains in order to give them antimicrobial properties.…”

In the present study, in situ crosslinked films were easily prepared by the spray deposition of Phase A, composed by sodium alginate (Alg), hydroxypropyl methylcellulose (HPMC), ε‐polylysine (ε‐PL), and plasticizers, followed by the spray deposition of Phase B (Ca2+ ions) on polystyrene dishes. The effect of the amount of plasticizer, HPMC, and ε‐PL in Phase A on the films properties was explored in a set of 12 systems. Fourier transform infrared vibrational spectroscopy in the attenuated total reflectance mode revealed that plasticizers compete with Ca2+ ions for complexation with Alg. Films with high HPMC content and low content of plasticizer and ε‐PL presented the best mechanical properties. The best system presented Young modulus of 0.76 ± 0.10 GPa, water vapor transmission of 5.35 ± 0.28 mg cm−2 h−1, swelling ratio of 1374 ± 97%, 99.99% reduction against Gram‐negative Escherichia coli bacteria, and 99.9% reduction against Gram‐positive Staphylococcus aureus bacteria. © 2019 Wiley Periodicals, Inc.
