“…Thus, integrating nanotechnology into science education facilitates the exploration of interdisciplinary connections across different science curricula. Manou et al (2021) emphasized the critical importance of science teachers being conversant with nanotechnology applications, considering their novelty. Mastery in utilizing these applications in science teaching is requisite.…”

This study aimed to investigate the impact of a training program based on nanotechnology applications on the development of digital competencies among high school biology teachers. There is a gap between teachers' current digital competencies and the skills needed to effectively leverage nanotechnology in biology education. The study found statistically significant differences between pre-test and post-test scores on a digital competency assessment after teachers completed the nanotechnology training program. The program encompassed fundamental nanoscience knowledge, biology-specific applications, digital skills training, and hands-on activities. Results showed a large effect size, indicating the substantial impact of the intervention on enhancing teachers' digital competencies. Recommendations highlight integrating nanotechnology into science curricula and emphasize biology connections, problem-solving, content creation, and ethical considerations regarding advanced nanomaterials. Promoting teacher motivation and scientific inquiry is vital. The research addresses an urgent need to equip biology educators with digital skills aligned with rapidly evolving science and technology.

“…Through the clarification and analysis of the scientific content, on the one hand, the content is critically analyzed through leading scientific books and key publications of the field, and, on the other hand, its educational significance is highlighted. In the case of NST, the critical analysis of the NST content has already been documented [13]. In brief, through the close examination of a large number of published papers and books regarding the content of NST, the salient concepts of the field were identified.…”

“…Fourteen primary school teachers (PTs) (1 kindergarten) participated in a NST training program which consisted of three phases that lasted approximately 9 months in total (Figure 2). During the first 2 months, PTs were trained on salient NST concepts, phenomena, and applications, such as size and scale, lotus and gecko effects, water filtration systems, and models of nanoscale structures (e.g., models of nanoporous membranes) (approximately 27 h) (Table 1) [13,39]. Within this phase of the program, PTs were familiarized with the teaching methods that were implemented in order to be enabled to develop awareness about the modern field, such as inquiry-based teaching and learning, the Jigsaw method [40], and out-of-school activities etc.…”

Most of the modern technological applications we use in our daily life originate from the progress of Nanoscience–Nanotechnology (NST). The projection, showing the great impact that these advances are going to have on society, exhorts science education researchers to incorporate the modern field into educational contexts. Among the several issues that have to be dealt with, NST’s educational significance comes to the fore. This pilot study aims to examine whether both nano-trained primary school teachers and nano-trained students acknowledge the need for the inclusion of the NST content to school contexts. Fourteen primary school teachers and ten students, after their participation in an NST training course, were interviewed in order to provide their justifications. The results show that the vast majority of the participants acknowledge the educational significance of NST. The main arguments were associated with career possibilities, the relevance of the content to everyday life, and the need for nanoliteracy attainment. The results of this study can be used by NST education researchers in order to formulate a NST content structure for primary school nanoeducation.

“…The aim is to exploit these properties by gaining control of structures and devices at atomic, molecular, and supramolecular levels and to learn manufacture and use of these devices efficiently" [1][2][3][4]. The United States National Science Foundation defines nanoscience/nanotechnology as studies dealing with materials and systems with dimensions of 1-100 nanometers (nm) [5][6][7].…”

In this study, metallic nanoparticles of copper were synthesized by the green method using an aqueous solution of Solenostemma argel extract. The extract was mixed well with cupric nitrate trihydrate. The plant extract acts as both a reducing and stabilizing agent. The prepared nanoparticles are found to be stable in the aqueous solution of the plant extract over seven months at room temperature (25 °C). The prepared copper nanoparticles were characterized by scanning electron microscopy (SEM) and UV-vis spectrum analysis. The scanning electron micrograph showed spherical nanoparticles in 30-50 nm size. These nanoparticles exhibited surface Plasmon absorption resonance (SPR) in the visible region. Also, they exhibited interesting anti-bacterial activity against Gram-positive and Gram-negative bacteria.
