“…Consumer perception, acceptance and knowledge of nanotechnology ( Cummings et al, 2021 ) may also be an impediment to food application. The majority of respondents (67%) indicated that they had little knowledge and understanding of nanotechnology, nanomaterials, and nanoproducts, and about 42% responded they had little understanding of its effects on food ( Arabeyyat, Jamaliah & Khalaf, 2022 ). Due to this low level of awareness, consumers are unable to make an informed evaluation of the potential risks to health and the environment ( Ummi & Siddiquee, 2019 ).…”

Background Increased awareness of the relationship between certain components in food beyond basic nutrition and health has generated interest in the production and consumption. Functional foods owe much of their health benefits to the presence of bioactive components. Despite their importance, their poor stability, solubility, and bioavailability may require the use of different strategies including nano-delivery systems (NDS) to sustain delivery and protection during handling, storage, and ingestion. Moreover, increasing consumer trend for non-animal sourced ingredients and interest in sustainable production invigorate the need to evaluate the utility of plant-based NDS. Method In the present study, 129 articles were selected after screening from Google Scholar searches using key terms from current literature. Scope This review provides an overview of current trends in the use of bioactive compounds as health-promoting ingredients in functional foods and the main methods used to stabilize these components. The use of plant proteins as carriers in NDS for bioactive compounds and the merits and challenges of this approach are also explored. Finally, the review discusses the application of protein-based NDS in food product development and highlights challenges and opportunities for future research. Key Findings Plant-based NDS is gaining recognition in food research and industry for their role in improving the shelf life and bioavailability of bioactives. However, concerns about safety and possible toxicity limit their widespread application. Future research efforts that focus on mitigating or enhancing their safety for food applications is warranted.

The use of conceptual change frame of instruction (CCFI) model is encouraging and selfmotivating to address the persistent complementary conceptions of the students. However, the educators always face some difficulties in explaining the intellectual and decisive scientific concepts. The purpose of this study was to appraise the efficacy of the CCFI model in correcting the misconceptions of undergraduate chemistry students. Prior to the implementation of the CCFI model, an assessment of pre-existing knowledge of the students was performed through the structure of the observed learning outcomes (SOLO) taxonomy. For this purpose, a quasi-experimental research design was carried out. A total of 70 chemistry students from Public Sector University, divided into two intact groups, were cross-examined for the study. Further, before and after the CCFI model, an achievement test based on Chemistry concepts was conducted, covering all six cognitive domains of the Bloom taxonomy of educational objectives. Data analysis revealed that the CCFI model had a statistically significant impact on undergraduate students for elimination of their misconceptions about Chemistry.

Nanoscale Science and Technology (NST) is a rapidly evolving field with profound implications for various industries and our everyday lives. However, misconceptions among learners can hinder their ability to grasp the fundamental concepts of NST, thereby impeding their potential contributions to this advancing domain. Concept maps (CM) and conceptual change texts (CCT) are graphical and written representations of knowledge that enable learners to visualize relationships between concepts and assess the coherence of their understanding. In this pursuit, we engage with the concept of rehabilitation for misconceptions, viewing the learning process as a transformative journey akin to cognitive rehabilitation. Through this CM-CCT constructivist approach, learners are encouraged to engage in critical reflection, self-questioning, and peer discussions, which facilitate the identification of misconceptions. Moreover, CM-CCT provide a structured framework for presenting accurate information about NST, offering a clear depiction of the hierarchical and interconnected nature of nanoscale phenomena. The aim of this study was to evaluate the effectiveness of CM-CCT in correcting the misconceptions of undergraduate university students regarding nanotechnology and the taxonomy of nonmaterial. Prior to the implementation of the CM-CCT, an assessment of pre-existing knowledge of the students was performed through the structure of the observed learning outcomes (SOLO) taxonomy. A quasi-experimental research design was carried out. A total of 70 undergraduate university students, divided into two intact groups, were cross-examined for the study. Further, before and after the instructional tools, an achievement test based on nanotechnology and classification of nonmaterial was conducted, covering all six cognitive domains of the Bloom taxonomy of educational objectives. Data analysis revealed that the instructional tools based on constructivist approach had a statistically significant impact on students for elimination of their misconceptions about nanotechnology, nano science and classification of nonmaterial.
