“…This high variety of adhesive systems with, e.g., permanent or temporary holdfast, the ability to bond on different surfaces and with curing times from milliseconds to minutes, surely offer a broad portfolio, suitable for every desirable medical application. In the following chapter, we aim to give a short overview of existing and prospective biological adhesive systems; further details could be found elsewhere [ 48 , 49 , 50 ].…”

“…While most frogs and salamanders use toxic or noxious secretions as defence, some species instead use adhesives [ 50 , 70 ]. Upon release through epidermal glands on the body and trunk [ 71 ], the secretion of those amphibians cures immediately, enabling an irreversible and strong bonding (tensile strength >0.07 MPa, shear stress >2.8 MPa on wood) to biological (human skin) and artificial (wood, glass, metal) surfaces [ 55 , 72 ].…”

This article deliberates about the importance of polymer-based bioadhesive biomaterials’ medical application in healthcare and in redefining healthcare management. Nowadays, the application of bioadhesion in the health sector is one of the great interests for various researchers, due to recent advances in their formulation development. Actually, this area of study is considered as an active multidisciplinary research approach, where engineers, scientists (including chemists, physicists, biologists, and medical experts), material producers and manufacturers combine their knowledge in order to provide better healthcare. Moreover, while discussing the implications of value-based healthcare, it is necessary to mention that health comprises three main domains, namely, physical, mental, and social health, which not only prioritize the quality healthcare, but also enable us to measure the outcomes of medical interventions. In addition, this conceptual article provides an understanding of the consequences of the natural or synthetic polymer-based bioadhesion of biomaterials, and its significance for redefining healthcare management as a novel approach. Furthermore, the research assumptions highlight that the quality healthcare concept has recently become a burning topic, wherein healthcare service providers, private research institutes, government authorities, public service boards, associations and academics have taken the initiative to restructure the healthcare system to create value for patients and increase their satisfaction, and lead ultimately to a healthier society.

“…Noch sind die naturinspirierten Materialien nur unter hohem technischen Aufwand und beachtlichen Kosten zu produzieren. Daher suchen Wissenschaftler immer weiter nach Ideen aus der Natur, um die Synthese biologischer Hochleistungspolymere zu vereinfachen . Ein vielversprechendes Vorbild dafür könnte das Beutefangsekret der Stummelfüßer (Onychophora, Abbildung ) sein, das seit 2012 eingehend erforscht wird.…”

Zusammenfassung Der biologische Sekundenkleber der Stummelfüßer ist eine Quelle der Inspiration für die nachhaltige Produktion „intelligenter“ polymerbasierter Materialien. In der Natur jagen die Stummelfüßer ihre Beute mit dem proteinreichen Sekret, welches in der Lage ist, enorm belastbare Fasern zu bilden. Die Anleitung für diese Transformation ist in den Bausteinen programmiert und läuft selbstständig ohne jegliche Regulation durch den tierischen Körper ab. Elektrostatische Wechselwirkungen zwischen geladenen Proteinarealen und Ionen bewirken die Faltung, Zusammenlagerung (Koazervation) und Stabilisierung der Bausteine in nanoskopisch kleine Speicherpartikel. Mechanische Einwirkung von außen löst den Umwandlungsprozess zu reißfesten Fasern aus. Die Speicherpartikel verschmelzen, die Proteine entfalten sich teilweise und gehen miteinander starke Bindungen ein. Die physikalisch‐chemischen Prinzipien werden sich künftig extrahieren lassen und neue Wege der Biomaterialsynthese ermöglichen.

“…The production of mucus is a prime example of a chemical response to predation risk which has been recorded amongst echinoderms (Flammang, Demeuldre, Hennebert, & Santos, ), fish (Schubert, Munday, Caley, Jones, & Llewellyn, ; Shephard, ), arthropods (Betz & Kölsch, ) and amphibians (Arnold, ; Evans & Brodie, ; Graham, Glattauer, Li, Tyler, & Ramshaw, ). Such bioadhesives are typically secreted quickly and exhibit a rapid curing process, sometimes within milliseconds (von Byern et al, ). These secretions are produced at the onset of an attack, most noticeably mechanical stimulation, acting as a protective barrier or overall deterrent that reduces the chances of the prey species from being consumed.…”

Adhesive defence mucus secretions in the red triangle slug (Triboniophorus graeffei) can incapacitate adult frogs

Gastropods are known to secrete mucus for a variety of purposes, including locomotion, reproduction, adhesion to surfaces and lubrication. A less commonly known function of mucus secretion in this group involves its use as a defence against predation. Amongst the terrestrial slugs, mucus that serves this particular purpose has been studied for only a handful of species under laboratory conditions, where it is thought to be produced to make individuals unpalatable or difficult to consume. However, the mechanisms of how these defensive secretions operate and their effectiveness in deterring predation in the natural world have not been described in much detail. In this study, we provide evidence of adhesive mucus secretions in the red triangle slug (Triboniophorus graeffei) as an adaptation against predation. Field observations of a large red‐eyed green tree frog (Litoria chloris) trapped in the mucus secretions of a nearby T. graeffei revealed that this mucus serves to incapacitate predators rather than just an overall deterrence. Mechanical stimulation of T. graeffei under laboratory conditions revealed that adhesive secretions were produced from discrete sections of the dorsal surface when disturbed, leading to the production of a highly sticky and elastic mucus that was unlike the thin and slippery mucus used during locomotion. The adhesiveness of the defensive secretions was strengthened and reactivated when in contact with water. This appears to not only be the first description of defensive mucus production in this slug species but one of the first natural observations of slug secretions incapacitating a relatively large vertebrate. The biomechanical properties of this mucus and its ability to maintain and strengthen its hold under wet conditions make it potentially useful in the development of new adhesive materials.
