“…SA-MA/CS-GA/EDC/NHS/G was 3 times more effective than itself, as shown by quantitatively characterising the area of the inhibition circle (Figure 4B). 30 The three phenolic hydroxyl groups in gallic acid, as well as the positively charged groups of CS, provided support for the antibacterial action of SA-MA/CS-GA/EDC/NHS/G cryogels. As a result of interactions between the positively charged CS molecule and the negatively charged bacterial membrane, bacterial proteins and other constituents seep out and die.…”

Cryogel wound dressings based on natural polysaccharides perfectly adhere to irregular wounds for rapid haemostasis and easy disassembly

Skin injuries can have unexpected surfaces, leading to uneven wound surfaces and inadequate dressing contact with these irregular surfaces. This can decrease the dressing's haemostatic action and increase the healing period. This study recommends the use of sticky and flexible cryogel coverings to promote faster haemostasis and efficiently handle uneven skin wounds. Alginate cryogels have a fast haemostatic effect and shape flexibility due to their macroporous structure. The material demonstrates potent antibacterial characteristics and enhances skin adherence by adding grafted chitosan with gallic acid. In irregular defect wound models, cryogels can cling closely to uneven damage surfaces due to their amorphous nature. Furthermore, their macroporous structure allows for quick haemostasis by quickly absorbing blood and wound exudate. After giving the dressing a thorough rinse, its adhesive strength reduces and it is simple to remove without causing any damage to the wound. Cryogel demonstrated faster haemostasis than gauze in a wound model on a rat tail, indicating that it has considerable potential for use as a wound dressing in the biomedical area.

Nanotechnological Manipulation of Nutraceuticals and Phytochemicals for Healthy Purposes: Established Advantages vs. Still Undefined Risks

Numerous foods, plants, and their bioactive constituents (BACs), named nutraceuticals and phytochemicals by experts, have shown many beneficial effects including antifungal, antiviral, anti-inflammatory, antibacterial, antiulcer, anti-cholesterol, hypoglycemic, immunomodulatory, and antioxidant activities. Producers, consumers, and the market of food- and plant-related compounds are increasingly attracted by health-promoting foods and plants, thus requiring a wider and more fruitful exploitation of the healthy properties of their BACs. The demand for new BACs and for the development of novel functional foods and BACs-based food additives is pressing from various sectors. Unfortunately, low stability, poor water solubility, opsonization, and fast metabolism in vivo hinder the effective exploitation of the potential of BACs. To overcome these issues, researchers have engineered nanomaterials, obtaining food-grade delivery systems, and edible food- and plant-related nanoparticles (NPs) acting as color, flavor, and preservative additives and natural therapeutics. Here, we have reviewed the nanotechnological transformations of several BACs implemented to increase their bioavailability, to mask any unpleasant taste and flavors, to be included as active ingredients in food or food packaging, to improve food appearance, quality, and resistance to deterioration due to storage. The pending issue regarding the possible toxic effect of NPs, whose knowledge is still limited, has also been discussed.

“…As regards the microbial growth and metabolism monitoring, Isothermal Calorimetry (IC or ITC in the case of titration), represents a suitable complementary/alternative to the traditional approaches and has already been applied to the study of the metabolic activity of bacteria in opaque liquids, on surfaces and in solids in a wide range of conditions [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. The instrumental output, i.e., the heat flow (HF), is a non-specific neat signal that reflects the overall energetic and kinetic picture of the bacteria activity in the real system under investigation i.e.…”

Protocols and guidelines were assessed in order to apply Isothermal Calorimetry as a complementary/alternative method to monitoring, during the shelf life, the microbial growth/metabolism in commercial fresh cut vegetables with random initial microbial population. Moreover, the endogenous microbial population was used as a biosensor to check the modifications occurred during long storage for aftermarket characterization in the frame of vegetable waste treatments. Validation was obtained following ready-to-use carrots highlighting the effects of the different exposed surface (cylinders, sticks and à-la-julienne cut) on the overall spoiling process during shelf life and green salad stored up to 14 days as regard the aftermarket characterization.
