“…There are registers of the use of sutures with linen and gold in Ancient Egypt, as well as the use of cat's intestine in Europe, during the Middle Age 2 . Approximately thousand years ago, the use of mandible of ants for the approximation of the edges of an injury has been reported in the medical Indian text Charaka Sanhita 3 Based on this knowledge, an absorbable surgical clamp (MU9102934-1) has been designed, emulating the mechanics of bite produced by the mandible of the ant Atta laevigata.…”

Approximately thousand years ago it was reported the use of mandibles of ants for suture. In this sense, bioinspired components, as absorbable surgical clamps, can be designed. This study is aimed to characterize the mandible of the ant Atta laevigata in order to help the selection of candidate biomaterials for application as surgical clamps. Three pairs of mandibles were used and ten nanoindenations were performed in each pair. The average hardness for the samples in the internal and external regions were 0.36 ± 0.06 GPa and 0.19 ± 0.04 GPa, respectively and the average elastic modulus for the internal and external regions were 6.16 ± 0.23 GPa and 2.74 ± 0.44 GPa, respectively. The morphology of the mandible was observed in detail by scanning electron microscopy, as well as Energy-dispersive X-ray spectroscopy. The average roughnesses on the internal and external regions, measured by atomic force microscopy, were 6.73 ± 0.90 nm and 11.87 ± 1.42 nm, respectively. From these results, it was possible to identify biomaterials that mimic the mandible behaviour for surgical clamp.

“…Polysaccharides of microbial origin, such as chitosan, alginate, xanthan gum, and cellulose, are another class of biomaterials that have gained considerable interest for medical use because of their properties, including that they are renewable, biodegradable, and mimic the components of the extracellular matrix, which make them key elements in biological processes (Pires and Moraes, 2015; Pires et al, 2015). Chitosan can be easily recovered from the cell wall of fungi such as A. niger, Rhizopus oryzae, Cunninghamella elegans , and Mucor indicus , among others (Pochanavanich and Suntornsuk, 2002; Franco et al, 2004; Ruholahi et al, 2016; Abdel-Gawad et al, 2017).…”

“…Cellulose synthesized (in abundance) by bacteria such as Gluconacetobacter xylinus (e.g., Huang C. et al, 2016) displays the same polymeric structure of cellulose from plants but is superior in its mechanical properties, purity, and uniformity, allowing the production of higher-quality devices (Pires et al, 2015). These devices include dialysis membranes and scaffolds for tissue engineering (Svensson et al, 2005).…”

Over thousands of years, modernization could be predicted for the use of microorganisms in the production of foods and beverages. However, the current accelerated pace of new food production is due to the rapid incorporation of biotechnological techniques that allow the rapid identification of new molecules and microorganisms or even the genetic improvement of known species. At no other time in history have microorganisms been so present in areas such as agriculture and medicine, except as recognized villains. Currently, however, beneficial microorganisms such as plant growth promoters and phytopathogen controllers are required by various agricultural crops, and many species are being used as biofactories of important pharmacological molecules. The use of biofactories does not end there: microorganisms have been explored for the synthesis of diverse chemicals, fuel molecules, and industrial polymers, and strains environmentally important due to their biodecomposing or biosorption capacity have gained interest in research laboratories and in industrial activities. We call this new microbiology Technological Microbiology, and we believe that complex techniques, such as heterologous expression and metabolic engineering, can be increasingly incorporated into this applied science, allowing the generation of new and improved products and services.

“…Diferentes atividades biológicas já foram descritas para a quitosana, como antimicrobiana e estimulante do processo cicatricial. 72,73 Entretanto, no que compete à terapia genética, é a habilidade de interagir com o material genético que torna atrativo o uso da quitosana. Um dos maiores limitantes do emprego da quitosana, não só em formulações para a terapia gênica ocular, mas para outras vias e aplicações, é a dificuldade na caracterização da matéria-prima.…”
