“…Antimicrobial agents have been widely applied in agriculture, the environment, medicine, textiles, food, food packaging, and other industries to protect individuals against microorganisms. Among the three types of commonly used antimicrobial agents, the inorganic ones exhibit high antimicrobial efficiency and good heat stability . However, there is an increasing concern about their potential perniciousness to the environment and human health from the leaching of heavy metals .…”

In this work, it is first reported that the poly (3‐hydroxybutyric acid) (PHB) oligomer with a few degrees of polymerization possesses effective antibacterial and antifungal properties. Two preparation methods for the PHB oligomer are described, namely, one‐step ring‐opening polymerization of β‐butyrolactone and extraction from the fermented PHB polymer. An appropriate amount of the synthesized PHB oligomer shows no physiological toxicity to the skin and major organs of mice. Topological application of the synthesized PHB oligomer imparts antimicrobial ability to non‐antibacterial fabrics with washing resistance. The synthesized PHB oligomer offers effective sterilization and promotes wound healing in infected nude mice. Most importantly, the PHB oligomer is also reactive to drug‐resistant bacteria. These results suggest that the PHB oligomer is not only a great candidate for antimicrobial modification but also a promising one for biomedical applications. Finally, the antimicrobial mechanisms of the PHB oligomer are revealed, and these include disruption of biofilm and the bacterial wall/membrane, leakage of the intracellular content, inhibition of protein activity, and change in the transmembrane potential.

“…Specifically, we have previously demonstrated that, feeding the discharger with metal-based precursors, anti-microbial or photocatalytic coatings can be obtained. 30,31 In this work, several deposition processes were optimized with the aim of obtaining the highest TiO2 mass fraction, without deterioration of the fabric substrate and needless time consumption, using surface and morphology characterization experimental results.…”

“…The antimicrobial activity of inorganic elements such as silver and copper is not as sensitive to inhibition by exogenous molecules such as lipids and proteins, and are generally more stable under changing temperature and pH conditions than organic antimicrobial molecules (Duncan, ; Krepker et al., ). Techniques such as plasma‐enhanced chemical vapor deposition (PECVD) can attach these metals as thin homogeneous films to inert surfaces without damaging the underlying material (De Vietro, Conte, Incoronato, Del Nobile, & Fracassi, ; Schäfer et al., ). The basic procedure involves vaporizing a metal in a gas such as argon then introducing the gas into a vacuum chamber being subjected to radio waves or a strong electromagnetic field.…”

“…The electromagnetic potential or radio frequency causes the atoms in the gas to become ionized and the gas changes to a plasma state. The reactive plasma gas is then evenly deposited on the metal substrate in nano‐meter‐sized clusters (Figure ; Brunon et al., ; De Vietro et al., ). De Vietro et al.…”

“…De Vietro et al. () generated an argon‐copper plasma under low pressure and deposited the copper on inert surfaces using an electrical field ranging in strength from 30 to 150 W. They found that a field strength of 150 W deposited the most amount of copper evenly on the surfaces, and this correlated with an increased inhibitory effect of the surface against inoculated Pseudomonas species (De Vietro et al., ). Similar PECVD techniques have been used to create other antimicrobial and biocompatible surfaces such as silver‐encapsulated textiles (Brunon et al., ), copper alloy‐coated stainless steel (Wrona et al., ), and medical‐grade polydimethylsiloxanes covered in a titanium dioxide film (Boudot, Kühn, Kühn‐Kauffeldt, & Schein, ).…”

Modern-day processing of meat products involves a series of complex procedures designed to ensure the quality and safety of the meat for consumers. As the size of abattoirs increases, the logistical problems associated with large-capacity animal processing can affect the sanitation of the facility and the meat products, potentially increasing transmission of infectious diseases. Additionally, spoilage of food from improper processing and storage increases the global economic and ecological burden of meat production. Advances in biomedical and materials science have allowed for the development of innovative new antibacterial technologies that have broad applications in the medical industry. Additionally, new approaches in tissue engineering and nondestructive cooling of biological specimens could significantly improve organ transplantation and tissue grafting. These same strategies may be even more effective in the preservation and protection of meat as animal carcasses are easier to manipulate and do not have the same stringent requirements of care as living patients. This review presents potential applications of emerging biomedical technologies in the food industry to improve meat safety and quality. Future research directions investigating these new technologies and their usefulness in the meat processing chain along with regulatory, logistical, and consumer perception issues will also be discussed.
