受褐藻黑角藻（Fucus serratus）分泌物湿润表面的显著粘附能力的启发，设计并表征了新型胶水。由间苯三酚、海藻酸盐和钙离子组成的制剂能够粘附在各种表面上。流变学数据表明，间苯三酚的存在降低了溶胶-凝胶过渡所需的Ca2+离子的数量，这表明海藻酸盐和间苯三酚之间存在相互作用。SAXS的数据支持这一说法。间苯三酚。粘接剂将猪组织结合在一起，粘接剂的强度为17-25千帕，这表明了作为软组织粘接剂应用的适当机械性能。
Inspired by the remarkable adhesive capabilities to wet surfaces of the secretes of the brown alga Fucus serratus, novel glues have been designed and characterized. Formulations composed of phloroglucinol, alginate, and calcium ions are capable of adhering to a variety of surfaces. Rheological data show that the presence of phloroglucinol lowers the amount of Ca2+ ions required for sol-gel transition, which indicates interactions between the alginate and the phloroglucinol. SAXS data support this claim. The phloroglucinol. adhesive binds porcine tissues together with an adhesive strength of 17-25 kPa, which indicates appropriate mechanical properties for application as a soft tissue adhesive.
