“…In this regard, Wei et al added Fe 3+ in the one‐pot preparation process of PAA to achieve the self‐healing properties of hydrogel via the combination of physical crosslinking network of poly(acrylic) acid with the dynamic migration of Fe 3+ , and then prepared the hydrogel with a rapid self‐healing rate. Mou et al combined synergistic oxidative crosslinking action with metal coordination, capped polyethylene glycol with catechol, and finally formed self‐healing gel using electrochemical mediation to process the solution of cation precursor. All these preparations of self‐healing hydrogels generated dynamic actions between the coordinated functional groups in the presence of ions and then accomplished the self‐healing of gel.…”

In this work, poly(acrylic) acid-chitosan @ tannic acid-aluminum ion (PAA-CS@TA-Al 3+ ) double-network hydrogel was prepared via prefabrication, blending method, and Al 3+ immersion method. The interaction between chitosan and tannic acid (CS@TA) was analyzed using Fourier transfer infrared spectra and UV-Vis spectra. The UV-Vis spectrum was also used to confirm the formation of ionic coordination in the gel. Then, the possible coordination modes were studied and analyzed. The microscopic pore structure and macroscopic strain behavior of the gel were analyzed using SEM and tensile testing, respectively, which verified that the tensile strength (≈32 KPa) and elongation at break (≈1700%) of the gel primarily resulted from its crosslinking structure. In addition, the gel also demonstrated a good self-healing performance with recovery ≈92.2% at 60 minutes.Hence, the proposed novel self-healing gel can provide inspiration for the preparation of future self-healing gels.

“…The reaction mechanism has been verified via UV-vis spectroscopy, and this characterization has been well used in the current study for identifying the coordination bond between catechol and metal. [39][40][41] In 2007, M. Bisaglia and the coworkers [42] reported the conversion from dopamine to dopamine-o-quinone, leukoaminochrome, and further aminochrome in the oxidation process under the metal ions effects. The authors used the UV-vis spectrum to detect the intermediate species.…”

Since then, lots of researches have been carried out to reveal the role of catechol in mussel adhesion behavior and devoted to incorporating the catechol functionality into synthetic materials. [7,8] Especially, catechol-metal-based materials have garnered considerable attention due to the strong interactions, diverse properties, and tunable structures. [9,10] Despite the interaction between catechol and metal ions is still not fully understood, significant progress has been made and many possible mechanisms have been proposed. The cross-linking process relies on versatile catechol-based chemistry.The synthetic catechol-metal-based materials usually exhibit excellent performance such as good adhesion, flexibility, conductivity, and high mechanical strength. [10][11][12] A wide consensus in relevant fields is that the type of metal ions is the main factor determining the properties of these materials. [13,14] This discovery raises the interest in exploring the unknown scientific and technical to synthetic novel catechol-metal-based functional materials. For example, the introduction of transition metal ions triggers efficient interactions with the catechol-containing groups. In the systems, the metal ions can act as chemical stimuli, cross-linking points, and tunable chelation ability. [15] As a typical example, iron ions (i.e., Fe 2+ and Fe 3+ ) have an obvious effect on the coordination between metal ions and catechol groups. [16][17][18] In previous reports, many researchers have focused on the specific introduction of various metal ions into the catechol-metal system. [19,20] It provided a new opportunity for various applications, such as water purification, biomedical engineering, wearable device, and responsible sensor.Besides, various chemical structures of catechol, including natural plant-derived phenols (e.g., dopamine, gallic acid, tannic acid (TA), and lignin) [21][22][23] and synthetic phenolic molecules (e.g., polyphenol and poly-catechol), [24] is still a subject of debate. Over 8000 articles about catechol-containing chemistry have been published and lead to numerous breakthroughs in the fields of chemistry and materials. In catecholmetal systems, phenolic compounds display diverse properties, such as metal coordination, antioxidant activity through Catechol plays an important role in many systems by interacting with organic (e.g., amino acids) and inorganic (e.g., metal ions, metal oxides) compounds. Catechol cross-linked polymer networks exhibit significant mechanical strength, good adhesiveness, and life-like characteristics. Recently, catechol-metal coordination materials have aroused increasing interest in multifunctional applications. Numerous influential studies have demonstrated that the type of metal ions and the structure of phenolic (such as natural phenolic (e.g., tannic acid, gallic acid, and lignin) or synthetic catechol-containing polymers) play important roles in the formation of catechol-metal coordination complexes. Although catechol-metal-based materials have been successfully pr...

“…On the other hand, cardiac tissue engineering (CTE) aims to replace or repair cardiac tissue damage to facilitate tissue regeneration by creating engineered three-dimensional (3D) cardiac patches and implantation at the injured site. − Nevertheless, to stimulate effective CTE, it is crucial to prepare a promising synthetic microenvironment that can imitate the local cardiac extracellular matrix (ECM). , Also, various reports show that microparticles − and hydrogels , are very effective in repairing heart tissue. However, these matrices as scaffolds in addition to compatibility , must show good conductivity of the electric wave. , In fact, the possibility of improving the mechanical properties of substrates via metal NPs by changing the cross-link composition and increasing the self-healing capacity due to the improved capacity and redox of substrates used with metal ions can increase the hope of improving heart problems . On the other hand, toxic scaffolds may limit the therapeutic perspective of the implanted patch and can result in graft rejection, immunogenic response, cell apoptosis, and associated adverse effects on the health of the patient .…”

In recent years, an increasing rate of mortality due to myocardial infarction (MI) has led to the development of nanobased platforms, especially gold nanoparticles (AuNPs), as promising nanomaterials for diagnosis and treatment of MI. These promising NPs have been used to develop different nanobiosensors, mainly optical sensors for early detection of biomarkers as well as biomimetic/bioinspired platforms for cardiac tissue engineering (CTE). Therefore, in this Review, we presented an overview on the potential application of AuNPs as optical (surface plasmon resonance, colorimetric, fluorescence, and chemiluminescence) nanobiosensors for early diagnosis and prognosis of MI. On the other hand, we discussed the potential application of AuNPs either alone or with other NPs/polymers as promising three-dimensional (3D) scaffolds to regulate the microenvironment and mimic the morphological and electrical features of cardiac cells for potential application in CTE. Furthermore, we presented the challenges and ongoing efforts associated with the application of AuNPs in the diagnosis and treatment of MI. In conclusion, this Review may provide outstanding information regarding the development of AuNP-based technology as a promising platform for current MI treatment approaches.
