Advances in stabilization of metallic nanoparticle with biosurfactants- a review on current trends

Recently, research based on new biomaterials for stabilizing metallic nanoparticles has increased due to their greater environmental friendliness and lower health risk. Their stability is often a critical factor influencing their performance and shelf life. Nowadays, the use of biosurfactants is gaining interest due to their sustainable advantages. Biosurfactants are used for various commercial and industrial applications such as food processing, therapeutic applications, agriculture, etc. Biosurfactants create stable coatings surrounding nanoparticles to stop agglomeration and provide long-term stability. The present review study describes a collection of important scientific works on stabilization and capping of metallic nanoparticles as biosurfactants. This review also provides a comprehensive overview of the intrinsic properties and environmental aspects of metal nanoparticles coated with biosurfactants. In addition, future methods and potential solutions for biosurfactant-mediated stabilization in nanoparticle synthesis are also highlighted. The objective of this study is to ensure that the stabilized nanoparticles exhibit biocompatible properties, making them suitable for applications in medicine and biotechnology.

Why Do Firms Implement Responsible Innovation? The Case of Emerging Technologies in South Korea

With the rise of responsible innovation (RI) initiatives in firms that commercialize innovation in recent years, experts have argued that in order for RI to succeed, practical issues must be considered. Accordingly, this paper explores RI from the perspective of Korean emerging technology development firms. Although social benefits are expected from RI, which aims to reduce the side effects of innovations for society, the implementation of RI requires changing firms' existing rules and routines. Therefore, predicting benefits and costs from the firm's perspective can shed light on the likelihood that RI will succeed. In this study, through an expert survey, the relative weights of RI-related benefit criteria (technological level, economic performance, and public contribution) and cost criteria (anticipation, reflexivity, inclusion, and responsiveness) were analyzed. On this basis, trends in priorities for RI levels were evaluated from present and future perspectives. Unexpectedly, firms recognized that even if constraints such as RI impose greater costs, they will eventually bring greater benefits. This finding indicates that innovation induced by RI overcomes obstacles, offsets costs, and then finally increases firms' competitiveness, and that firms are willing to do good for society through RI. In the long term, a firm's ethical activities may eventually result in improved performance by its management. Therefore, it can be concluded that, even if RI is enforced in a compulsory manner, it is highly likely that it can be well established and promoted even in firms that consider profit first.

Harnessing symbiotic plant-fungus interactions to unleash hidden forces from extreme plant ecosystems

Global climate change is arguably one of the biggest threats of modern times and has already led to a wide range of impacts on the environment, economy, and society. Owing to past emissions and climate system inertia, global climate change is predicted to continue for decades even if anthropogenic greenhouse gas emissions were to stop immediately. In many regions, such as central Europe and the Mediterranean region, the temperature is likely to rise by 2-5 °C and annual precipitation is predicted to decrease. Expected heat and drought periods followed by floods, and unpredictable growing seasons, are predicted to have detrimental effects on agricultural production systems, causing immense economic losses and food supply problems. To mitigate the risks of climate change, agricultural innovations counteracting these effects need to be embraced and accelerated. To achieve maximum improvement, the required agricultural innovations should not focus only on crops but rather pursue a holistic approach including the entire ecosystem. Over millions of years, plants have evolved in close association with other organisms, particularly soil microbes that have shaped their evolution and contemporary ecology. Many studies have already highlighted beneficial interactions among plants and the communities of microorganisms with which they coexist. Questions arising from these discoveries are whether it will be possible to decipher a common molecular pattern and the underlying biochemical framework of interspecies communication, and whether such knowledge can be used to improve agricultural performance under environmental stress conditions. In this review, we summarize the current knowledge of plant interactions with fungal endosymbionts found in extreme ecosystems. Special attention will be paid to the interaction of plants with the symbiotic root-colonizing endophytic fungus Serendipita indica, which has been developed as a model system for beneficial plant-fungus interactions.
