Decellularized liver-derived extracellular matrix is a unique combination of a complex milieu of growth factors and proteins that stimulate biochemical, physical, and mechanical cues to the cells. However, the lack of mechanical strength hindering the applicability of extracellular matrix (ECM) is an outstanding challenge. Herein, to deal with this problem, decellularized kelp is introduced as a crosslinking material thereby strengthening the physical structure of ECM for its utilization as a wound-healing material. Consequently, a significant architectural change is observed in the ECM by forming a solid-shaped scaffold. Nevertheless, the hindrance of high pH is addressed by incorporating the acidic drug p-coumaric acid. To evaluate the innate regenerative abilities, the scaffolds are applied to rat excisional wounds. A remarkable wound healing capability is demonstrated by both the EK scaffolds, but a faster regeneration is achieved with only EK-20@cou. The speculated hypothesis is that the incorporation of p-coumaric acid can offer many additional bioactive benefits to the scaffold such as remarkable biocompatibility, antioxidant, and anti-bacterial properties that are deliberately supported by the in vitro results. In silico molecular simulations (MS) validated that p-Cou released from the EK-20@Cou scaffold is accountable for the observed extraordinary regenerative behavior as compared to EK-20(PW).

Wet adhesion is a challenging process that requires successful interactions between the two surfaces of interest. Current adhesives may offer sufficient strength but often contain toxic components. Thus, when the field of adhesion meets bioinspiration, there is lots of potential for finding an innovative solution. Here, inspired by mucilaginous seeds and by using refined fiber structures provided by renewable materials, it is demonstrated how to build a comparably strong wet adhesive system. The process involves the controlled fibrillation of a wood surface followed by the application of a macromolecular coating employing the main component found in mucilaginous seeds. Moreover, the additional introduction of a thermo‐responsive polymer into the system allows for obtaining control over the strength and the compliance of the detachment process. Thus, this study demonstrates how combining renewable materials with a multi‐step coating process offers an environmentally friendly solution that pinpoints a promising path toward bio‐based wet adhesives.

Durian (Durio zibethinus) is a popular native tropical fruit and is largely produced in Southeast Asia. In Indonesia, 1.71 million metric tons of durian were produced in 2022. However, this high production may lead to organic waste issues due to the large amount of durian rind generation. About 60 – 75% of the durian is the rind, which is mostly discarded, hard to be decomposed, and not utilized optimally. Meanwhile, the durian rind poses as a potential reservoir containing high concentrations of cellulose and pectin. Therefore, this research aimed to (1) extract pectin content from durian rind and (2) synthesize and characterize pectin-based biopolymer films. First, the pectin was extracted from dried durian rind powder using acid extraction and alcoholic precipitation methods. Then, biopolymer synthesis was done by mixing formulations of pectin, chitosan, ethylene glycol, and glycerol solutions to form thin films. About 0.13 – 0.71 g of pectin (0.46% of the pectin yield) was extracted per 100 g of dried durian rind powder. The FTIR spectroscopy results of the extracted pectin confirmed the presence of the O - H groups at 3327.83 cm-1, which indicated the pyranose ring, the main characteristic of pectin. Pectin-based biopolymer films were produced with thickness, transparency, and tensile strength of 0.01 – 0.07 mm, 7.40 - 40.50, and 1.26 – 2.69 MPa, respectively. The findings of the soil burial degradation test for biodegradability showed that the biopolymer experienced weight loss of up to 62% in 14 days. Considering the potential utilization of the durian rind for developing biopolymers as value-added bioproducts from agricultural biomass, tropical fruit waste management should be done properly in the future. This also can be offered as one of the alternative solutions for plastic substitution with proper development in the future.
