“…Definitely, the porous morphology of the patch surface also plays a major role for wetting behavior. For instance, Liu et al showed that the WCA of pristine PLA was 129.2° when it is prepared in the form of randomly grown nanofibers [ 30 ]. The Cassie–Baxter model suggests that an indistinctly hydrophobic material gets more hydrophobic with the increasing roughness [ 31 ].…”

Marine Algae Incorporated Polylactide Acid Patch: Novel Candidate for Targeting Osteosarcoma Cells without Impairing the Osteoblastic Proliferation

Biodegradable collagen-based materials have been preferred as scaffolds and grafts for diverse clinical applications in density and orthopedy. Besides the advantages of using such bio-originated materials, the use of collagen matrices increases the risk of infection transmission through the cells or the tissues of the graft/scaffold. In addition, such collagen-based solutions are not counted as economically feasible approaches due to their high production cost. In recent years, incorporation of marine algae in synthetic polymers has been considered as an alternative method for preparation grafts/scaffolds since they represent abundant and cheap source of potential biopolymers. Current work aims to propose a novel composite patch prepared by blending Sargassum vulgare powders (SVP) to polylactide (PLA) as an alternative to the porcine-derived membranes. SVP-PLA composite patches were produced by using a modified solvent casting method. Following detailed material characterization to assess the cytocompatibility, human osteoblasts (HOBs) and osteosarcoma cells (SaOS-2) were seeded on neat PLA and SVP-PLA patches. MTT and BrdU assays indicated a greater cytocompatibility and higher proliferation for HOBs cultured on SVP-PLA composite than for those cultured on neat PLA. SaOS-2 cells cultured on SVP-PLA exhibited a significant decrease in cell proliferation. The composite patch described herein exhibits an antiproliferative effect against SaOS-2 cells without impairing HOBs’ adhesion and proliferation.

“…Such materials were shown to have excellent bacterial antiadhesion characteristics against both E. coli O157:H7 and S. aureus . Similar nanoporous structures can also be prepared by electrospinning process, which is more commonly used for organic and polymeric materials (Liu & Yuan, 2018; Ma et al., 2005).…”

Illness as the result of ingesting bacterially contaminated foodstuffs represents a significant annual loss of human quality of life and economic impact globally. Significant research investment has recently been made in developing new materials that can be used to construct food contacting tools and surfaces that might minimize the risk of cross‐contamination of bacteria from one food item to another. This is done to mitigate the spread of bacterial contamination and resultant foodborne illness. Internet‐based literature search tools such as Web of Science, Google Scholar, and Scopus were utilized to investigate publishing trends within the last 10 years related to the development of antimicrobial and antifouling surfaces with potential use in food processing applications. Technologies investigated were categorized into four major groups: antimicrobial agent–releasing coatings, contact‐based antimicrobial coatings, superhydrophobic antifouling coatings, and repulsion‐based antifouling coatings. The advantages for each group and technical challenges remaining before wide‐scale implementation were compared. A diverse array of emerging antimicrobial and antifouling technologies were identified, designed to suit a wide range of food contact applications. Although each poses distinct and promising advantages, significant further research investment will likely be required to reliably produce effective materials economically and safely enough to equip large‐scale operations such as farms, food processing facilities, and kitchens.

“…The modified nanofiber membranes can separate oil and water with an efficiency of 99% simply using gravitational force as shown in Figure 11. [50,81] Similarly, by incorporating polydopamine, silver nanoparticles, [82] and β-cyclodextrins [83] on PLA nanofibers increased the hydrophobicity and permeation fluxes for a wide variety of oils and a desirable separation performance of ≈95%.…”

Studies involving bio‐based nanofibers are well utilized in the field of energy, catalysis, electronics, and environmental science. In this review, the importance of utilizing bio‐based materials for the development and optimization of multiplexed nanofibers and the modifications adopted to overcome the drawbacks of conventional electro‐spinning to facilitate better production rates, enhanced adsorption, and its potential in removing heavy metal ions, dyes, and other contaminants polluting the environment are highlighted. This work provides the readers the ability to understand the complexity in fabrication of bio‐based nanofibers focusing primarily on chitosan, cellulose, and protein‐based nanofibers and their mechanism toward quenching/degradation of water contaminants. In addition, it also provides the advantages of using bio‐based materials over synthetic materials for the development of nanofibers.
