Biomass Derived and Biomass Inspired Polymers in Pharmaceutical Applications

Coordination Complexes and One-Step Assembly of Lignin for Versatile Nanocapsule Engineering

“…When the horn is used at 40 W, the system becomes less polydisperse compared to the capsules formed by the tip, as shown by the difference between the maximum and minimum dimensions found at the microscopy analysis (0.9−3 μm for the horn based generation of capsules (entry 6) whereas the capsule size can reach up to 6 μm when using the ultrasonication tip (entry 5)). The same effect of formation of capsules with sizes in a smaller range is noticed when increased power is used independently of the sonication probe (entries 7,8). Other than that, these findings indicate that the scaling up process using the ultrasonication horn for the sonication of an eventual larger volume is not totally equivalent to the simple batch experiment and does not lead directly to the obtention of the same type of capsules.…”

“…Despite the fact that the use of biopolymers, primarily cellulose, is now considerable, lignin, the second most abundant biopolymer which accounts for 15–30% of biomass, is a vastly underutilized source of aromatic compounds . Besides its polyphenolic character, lignin offers a wide range of additional features, such as aggregation properties, − high biocompatibility, ability to absorb UV light, and antioxidant activity that render it ideal for the production of novel, high-performance concepts and products using the lignin, coming either as byproduct of current processes or from emerging platforms such as the biorefinery. , …”

Impact of the Hydration States of Polymers on Their Hemocompatibility for Medical Applications: A Review

“…PLGA is the result of the copolymerization of lactic acid (LA) and glycolic acid (GA) and corresponds to a saturated poly(α-hydroxy ester) ( Figure 16 ). This polymer presents good biocompatibility and biodegradability, which can be tailored by controlling the M w of the polymer and the ratio between lactic and glycolic acid [ 63 ]. Commonly used LA:GA ratios are 25:75, 50:50, 75:25, and 85:15, all of them with different T g values, degree of crystallinity, and degradation rates.…”

Fractional Precipitation of Wheat Straw Organosolv Lignin: Macroscopic Properties and Structural Insights

“…4,5 Only recently, bigger global players and promising newcomers in the biorefinery business started to view the lignin-containing streams as an additional source for augmented revenues. 5 Consequently, different higher quality lignins are available nowadays for potential applications in sectors of material science, functional cosmetics, and eventual biomedical devices (Figure 1); 6 for example, the LignoBoost lignin that is obtained by a novel process for the precipitation of lignin after standard kraft pulping 7 and lignins obtained in industrialized organosolv pulping processes, for example, Alcell lignin 8 and CIMV Biolignin. 9 Any kind of higher value application, however, calls for a rather detailed structural understanding of the technically produced lignin of choice and the determination of basic thermal characteristics.…”

“…Being already present in nature with a myriad of different specifics, , industrial processes aimed at isolating the cellulose and hemicellulose parts of various types of lignocellulosic biomass further modify the structure of the lignin component, which is often obtained as a rather low-quality byproduct in biorefinery processes that were optimized with respect to the cellulose components. , Only recently, bigger global players and promising newcomers in the biorefinery business started to view the lignin-containing streams as an additional source for augmented revenues . Consequently, different higher quality lignins are available nowadays for potential applications in sectors of material science, functional cosmetics, and eventual biomedical devices (Figure ); for example, the LignoBoost lignin that is obtained by a novel process for the precipitation of lignin after standard kraft pulping and lignins obtained in industrialized organosolv pulping processes, for example, Alcell lignin and CIMV Biolignin…”
