“…[52][53][54] In particular, agarose (AGR) and potato starch (PS) are attractive and low-cost precursors for novel antimicrobial biopolymers. [54][55][56] AGR polymers have been widely employed in biomedical applications because of their facile manufacture, formability, degradability, tunable water solubility, and non-immunogenic features. 54,57,58 Similarly to AGR, PS is a renewable and sustainable biopolymer, representing one of the most commercially accessible feedstocks for degradable biopolymer films.…”

The development of sustainable biomaterials and surfaces to prevent the accumulation and proliferation of viruses and bacteria is highly demanded in healthcare areas. This study describes the assembly and full characterization of two new bioactive silver(I) coordination polymers (CPs) formulated as [Ag(aca)(μ-PTA)] n •5nH 2 O (1) and [Ag 2 (μada)(μ 3 -PTA) 2 ] n •4nH 2 O (2). These products were generated by exploiting a heteroleptic approach based on the use of two different adamantoid building blocks, namely 1,3,5-triaza-7phosphaadamantane (PTA) and 1-adamantanecarboxylic (Haca) or 1,3-adamantanedicarboxylic (H 2 ada) acids, resulting in the assembly of 1D (1) and 3D (2). Antiviral, antibacterial, and antifungal properties of the obtained compounds were investigated in detail, followed by their incorporation as bioactive dopants (1 wt %) into hybrid biopolymers based on acid-hydrolyzed starch polymer (AHSP). The resulting materials, formulated as 1@AHSP and 2@AHSP, also featured (i) an exceptional antiviral activity against herpes simplex virus type 1 and human adenovirus (HAd-5) and (ii) a remarkable antibacterial activity against Gram-negative bacteria. Docking experiments, interaction with human serum albumin, mass spectrometry, and antioxidation studies provided insights into the mechanism of antimicrobial action. By reporting these new silver CPs driven by adamantoid building blocks and the derived starch-based materials, this study endows a facile approach to access biopolymers and interfaces capable of preventing and reducing the proliferation of a broad spectrum of different microorganisms, including bacteria, fungi, and viruses.

“…Biomass resources, including the three categories of animals, plants and microbes resources, are ubiquitous in our planet [ 17 , 18 , 19 , 20 ]. Biomass-based materials, such as collagen-based materials [ 21 , 22 ], starch-based materials [ 23 , 24 ], chitosan-based materials [ 25 , 26 ], chitin-based materials [ 27 , 28 ], cellulose-based materials [ 29 , 30 ] and so on, derived from these biomass resources have been developed rapidly and display wide applications in various fields, such as textiles and agriculture, pharmaceutical/biomedicine, food packaging, energy and water treatment. As the most widely distributed and abundant polysaccharide in nature, cellulose has attracted more and more attention recently and the commercialization of viscose fibers, cellophane (regenerated cellulose film) and celluloids (cellulose nitrate) have been recognized as significant alternatives to non-degradable plastics [ 7 , 29 , 30 , 31 , 32 ].…”

Plastics displaying many merits have been indispensable in daily life and they still maintain the strong momentum of development. Nevertheless, petroleum-based plastics possess a stable polymer structure and most of them are incinerated or accumulated in the environment, leading to devastating impacts on our ecology system. Thus, exploiting renewable and biodegradable materials to substitute or replace these traditional petroleum-derived plastics is an urgent and important task. In this work, renewable and biodegradable all-biomass cellulose/grape-seed-extract (GSEs) composite films with high transparency and anti-ultraviolet performance were fabricated successfully from pretreated old cotton textiles (P-OCTs) using a relatively simple, green, yet cost-effective, approach. It is proved that the obtained cellulose/GSEs composite films exhibit good ultraviolet shielding performance without sacrificing their transparency, and their UV-A and UV-B blocking values can reach as high as nearly 100%, indicating the good UV-blocking performance of GSEs. Meanwhile, the cellulose/GSEs film show higher thermal stability and water vapor transmission rate (WVTR) than most common plastics. Moreover, the mechanical property of the cellulose/GSEs film can be adjusted by the addition of a plasticizer. Briefly, the transparent all-biomass cellulose/grape-seed-extracts composite films with high anti-ultraviolet capacity were manufactured successfully and they can be used as potential materials in the packaging field.
