Bio-Monomers Used in the Synthesis of Hydrogels
Natural bio-based monomers derived from plants or animals are widely used in the synthesis of hydrogels and their compounds for the production of biopolymers and biomaterials that are biocompatible, biodegradable, non-toxic and of high porosity, characteristics much sought after in the biomedical field.

Bio-Photonic Cavities
An eco-friendly approach to usual optical cavities, in which an electromagnetic radiation can release energy to matter by interacting with its molecular or atomic structure. Based on bio-inspired and biodegradable meta-surfaces, able to behave as a resonator for light, their optical response can be engineered at will to accomplish a particular optical task.

Bio-Residues Analysis of Fruit Crops
Food processing generates a large amount of bio-residues, which have become the focus of different studies aimed at valorizing this low-cost source of bioactive compounds. High fruit consumption is associated with beneficial health effects and, therefore, bio-waste and its constituents arouse therapeutic interest.

Bio-Vitrimers for Sustainable Circular Bio-Economy
The traditional polymer circular economy (CE) continues to be challenging due to its reprocessing/recycle ability; also, at the same time, newly developed substitute materials have not expressed similar performance to conventional materials involved in contemporary applications. Hence, linear approaches such as “take-make-use-waste” have severely affected sustainability modules where non-renewable resources have been used at maximum levels. In addition, sustainability is termed along with the circular economy paradigm in recent times, although material sustainability differs from CE material. The circular economy mainly focuses on the economic, environmental and social impacts, whereas sustainability is more about an ecological importance. Globally, frameworks have been formed to enhance the sustainable environment. The United Nations (UN) has designed 17 sustainable development goals to be enforced in all countries in order to reach the goal of a sustainable society by 2030.

Bioactive Agent-Loaded Electrospun Nanofiber Membranes
Despite the advances that have been achieved in developing wound dressings to date, wound healing still remains a challenge in the healthcare system. None of the wound dressings currently used clinically can mimic all the properties of normal and healthy skin. Electrospinning has gained remarkable attention in wound healing applications because of its excellent ability to form nanostructures similar to natural extracellular matrix (ECM). Electrospun dressing accelerates the wound healing process by transferring drugs or active agents to the wound site sooner.

Bioactive Coatings
       In this entry, we compiled a variety of creative approaches to generate antimicrobial bioactive coatings. The benefits are very desirable: to create surfaces that either repel the attachment of viable microorganisms or kill microorganisms on contact without inducing inflammation or cytotoxicity to host tissues.        These coatings may consist of nanoparticles of pure elements (e.g. silver, copper, and zinc), sanitizing agents and disinfectants (e.g., quaternary ammonium ions and chlorhexidine), antibiotics (e.g., cefalotin, vancomycin, and gentamacin), or antimicrobial peptides (AMP).        Many bioactive coatings may involve unique delivery systems to direct their antimicrobial capacity against pathogens, but not commensals.  Coatings may also contain multiple antimicrobial substances to widen antimicrobial activity across multiple microbial species.

Bioactive Compounds from Cardoon and Metabolic Disorders
Cardoon (Cynara cardunculus L.) is a Mediterranean plant and member of the Asteraceae family that includes three botanical taxa, the wild perennial cardoon (C. cardunculus L. var. sylvestris (Lamk) Fiori), globe artichoke (C. cardunculus L. var. scolymus L. Fiori), and domesticated cardoon (C. cardunculus L. var. altilis DC.). Cardoon has been widely used in the Mediterranean diet and folk medicine since ancient times. Today, cardoon is recognized as a plant with great industrial potential and is considered as a functional food, with important nutritional value, being an interesting source of bioactive compounds, such as phenolics, minerals, inulin, fiber, and sesquiterpene lactones.

Bioactive Compounds from Fruit Crop Wastes
The food industry as a whole is one of the main contributors for food losses and waste generation. To deal with such wastes, research and efforts have been made for the development and valorization of bioactive compounds present in food wastes such as leaves, peels, seeds, and pulp.

Bioactive Edible Films/Coatings Based in Gums and Starch
Edible films and coatings allow preserving fresh and processed food, maintaining quality, preventing microbial contamination and/or oxidation reactions and increasing the shelf life of food products. The structural matrix of edible films and coatings is mainly constituted by proteins, lipids or polysaccharides. However, it is possible to increase the bioactive potential of these polymeric matrices by adding phenolic compounds obtained from plant extracts. Phenolic compounds are known to possess several biological properties such as antioxidant and antimicrobial properties. Incorporating phenolic compounds enriched plant extracts in edible films and coatings contribute to preventing food spoilage/deterioration and the extension of shelf life.

Bioactive Flavonoid Hybrids Linked by 1,2,3-Triazole
Considering the biological activities of both flavonoids and 1,2,3-triazole ring, as well as the metabolic stability associated to this heterocyclic ring, hybridization of flavonoids with a 1,2,3-triazole ring has been widely reported over the last years. The most common way to obtain these hybrids is through the copper (I) catalyzed azide-alkyne cycloaddition (CuAAC), also known as Click Chemistry reaction. It was highlighted the flavonoid hybrids linked by the1,2,3-triazole ring obtained since 2017, including chalcones, flavones, flavanones and flavonols, among others, with antitumor, antimicrobial, antidiabetic, neuroprotective, anti-inflammatory, antioxidant, and antifouling activities.
