The purpose of this study was to develop flexible sensors for detection of different concentrations of bacteria, such as Pseudomonas aeruginosa and Staphylococcus aureus, in saline.

The sensors were fabricated using ink-jet printing technology and they consist of a pair of silver interdigitated electrodes printed on mechanically flexible substrates – foil and paper. In house measurement setup for testing and characterization of sensors has been developed. Structural, electrical and mechanical properties of flexible sensors have been determined and compared.

The characteristics of sensor – the resonant frequency as a function of different concentrations of each bacteria – are presented. The obtained results demonstrate different resonant frequencies for each dilution of Pseudomonas aeruginosa and Staphylococcus aureus in physiological saline.

Both sensors showed accurate measurements of bacterial count, which can be achieved with detection of resonant frequency, and this is reflective of the number of bacterial cells within a sample.

The findings suggest that the newly developed method based on measuring resonant frequency corresponds well with bacterial cell count, thus establishing a new proof-of-concept that such method can have significant applications in bacterial cell counting that are economic and easily maintained.

Fast, cost-effective, accurate and non-invasive method for detection of different bacteria from saline was developed.

For the first time, comparison between performances of flexible sensors on foil and paper for bacteria detection is demonstrated. Almost linear dependence between shift of resonant frequency of developed sensors and concentration of bacteria has been obtained.

This study delves into the significant impact of entrepreneurial leadership (EL), organizational innovation (OI) and competitive advantage (CA) on the sustainability of organizations in the Jordanian Islamic insurance sector. This study aims to unravel the intricate dynamics among these pivotal factors, highlighting their collective role in the sustained success and resilience of Islamic insurance companies in Jordan. By examining the synergistic interplay between EL, OI and CA, the research seeks to offer invaluable insights into cultivating a sustainable future for these institutions.

This study adopts a positivist, quantitative approach to investigate the relationships between EL, OI, CA and organizational sustainability (OS). Data collection was achieved through questionnaires in a cross-sectional analysis of these variables. Convenience sampling yielded 389 valid responses, an 81% response rate, ensuring a thorough understanding of the dynamics within this framework.

The findings from the study on Jordanian Islamic insurance companies highlight the critical role of EL in influencing organizational dynamics. The research establishes a positive relationship between EL and both OI and OS. Furthermore, it identifies a significant positive correlation between EL and CA, underscoring the importance of leadership in securing a competitive edge. This study also emphasizes the vital role of OI in bolstering OS and confirms that a strong CA enhances OS, reinforcing the interconnectivity of these essential organizational components.

This study provides important insights for professionals in the insurance sector, especially those within the Jordanian Islamic insurance industry. It emphasizes the crucial role of EL in fostering innovation, competitiveness and sustainability. By understanding the significance of EL, companies can adopt more dynamic and effective strategies in leadership, organizational development and strategic planning, thereby enhancing their overall performance and resilience.

By conceptualizing EL and OS as second-order constructs, this study seeks to provide a detailed understanding of how EL catalyzes OI, CA and sustainability in an organizational context. This approach contributes significantly to the broader discussion on EL and OS, particularly within the Arab region and specifically in Jordan, offering nuanced insights into their roles and interrelations in shaping organizational dynamics.
