“…Cactus mucilage is a colorless and clear liquid found in the pads of cactus plants; its main use is in storing water for the subsistence of the plant . NE is found mainly in the parenchyma and chlorenchyma of cactus cladodes. , The main compounds in NE are neutral sugars, carbohydrates, and proteins. − Researchers found that the proteins in the cactus mucilage, especially the macromolecular protein arabinogalactan, played an important role to lower the oil/water interfacial tension and formed oil-in-water emulsions. ,− Such structures have shown an interesting correlation with the main intermolecular forces found in surfactants and hydrophobic entities, as described by Gee and Israelachvili . Such studies corroborate that the effects of water seen with natural dispersants to produce smaller droplets is a result of surfactant-type sugars to increase the fluidity of hydrocarbon molecules as a function of the hydrophobic lyophilic balance (HLB) being driven toward forming O/W emulsions.…”

A natural surfactant was studied to simulate the dispersion process of crude oil in water. The interfacial phenomena of this natural dispersant was compared with a commercially available chemical dispersant, COREXIT EC9500A. This functional surfactant was extracted from the mucilage of the Opuntia ficus-indica cactus species. The evaluation to determine the efficacy to disperse crude oil of the cactus-based mucilage extract (nongelling extract, NE) was based on characterizing surface and interfacial tension, dispersion efficiency, mixing effects, salinity effects, stability, and droplets size distributions. We found that surface tension values follow a linear relationship with respect to the natural logarithm of the concentrations of NE. The application of NE in the water phase led to decreasing oil/water interfacial tensions. Surface tension tests were also used to quantify the effect of oil-in-water (O/W) emulsion ratios once either natural or commercialized dispersants were added. A key finding of our work is that the surface tension between typical 6% and 3% v/v O/W emulsions was significantly reduced with the addition of discrete amounts of NE. This result indicated that the dynamic balance between O/W and water-in-oil (W/O) emulsions was thermodynamically more stable toward O/W emulsion states with NE. We also found that O/W emulsions with higher dispersion effectiveness were formed for both 10 and 35 practical salinity units, as the dispersant to oil ratios increased, with a significant correlation to the mixing energy. We observed that the O/W emulsions with natural dispersants had a significantly smaller weighted average diameter compared to those with COREXIT EC9500A. Such a phenomenon can be explained by understanding intermolecular interactions due to the structure and type of dispersant. In conclusion, cactus-based mucilage extracts could be used as environmentally benign dispersants and, therefore, reduce negative social perceptions of the application of dispersants to clean up spilled oil.

Antitumor nanoparticles now confront several obstacles, including poor biocompatibility and biodegradability, quick removal, and a short cycle time, given the growing interest in surface membrane coating as a versatile platform for altering nanoparticles and overcoming the limitations of current nanodrug delivery methods. This paper reviews the recent progress of cells, synthetic polymers, polyphenols, and polysaccharides membrane coatings with favorable biocompatibility and biodegradability and easy surface modification on the surface of antitumor nanoparticle platforms, which can provide a promising strategy for endowing nanoparticles with specific and expected performance to optimize the efficiency of antitumor. Furthermore, multiple membrane combination strategies and additional biorecognition ligands modification on the membrane surface are supplied in an attempt to tackle the challenges of single membrane coating in a variety of tumor therapeutic applications and ultimately facilitate effective clinical transformation.

“…Thus, we will focus on discussing those three examples below. Of course, other biopolymer‐based coatings such as PLL, [ 120 ] pectin, [ 121 ] and fibronectin [ 122 ] are used in tissue engineering approaches as well. Moreover, some biopolymer‐based hybrid coatings, e.g., HA/chitosan, [ 123 ] HA/cationized gelatin, [ 124 ] and alginate/chitosan, [ 125 ] have been explored regarding tissue engineering applications.…”

It was a physicist, Wolfgang Pauli, who recognized a century ago that “God made the bulk; the surface was invented by the devil.” And indeed, adjusting the surface properties of materials has kept engineers and chemists busy since—and it still does. In the context of biomedical engineering, the key challenge is ensuring the functionality of an artificial object, which is inserted into the human body—an environment that passively and actively rejects foreign materials. Here, recent advances in this area while focusing on those approaches that employ surface coating strategies with biopolymers are summarized.
