Abstract

Purpose

This review provides an overview of recent advances in electrochemical sensors for analyte detection in saliva, highlighting their potential applications in diagnostics and health care. The purpose of this paper is to summarize the current state of the field, identify challenges and limitations and discuss future prospects for the development of saliva-based electrochemical sensors.

Design/methodology/approach

The paper reviews relevant literature and research articles to examine the latest developments in electrochemical sensing technologies for saliva analysis. It explores the use of various electrode materials, including carbon nanomaterial, metal nanoparticles and conducting polymers, as well as the integration of microfluidics, lab-on-a-chip (LOC) devices and wearable/implantable technologies. The design and fabrication methodologies used in these sensors are discussed, along with sample preparation techniques and biorecognition elements for enhancing sensor performance.

Findings

Electrochemical sensors for salivary analyte detection have demonstrated excellent potential for noninvasive, rapid and cost-effective diagnostics. Recent advancements have resulted in improved sensor selectivity, stability, sensitivity and compatibility with complex saliva samples. Integration with microfluidics and LOC technologies has shown promise in enhancing sensor efficiency and accuracy. In addition, wearable and implantable sensors enable continuous, real-time monitoring of salivary analytes, opening new avenues for personalized health care and disease management.

Originality/value

This review presents an up-to-date overview of electrochemical sensors for analyte detection in saliva, offering insights into their design, fabrication and performance. It highlights the originality and value of integrating electrochemical sensing with microfluidics, wearable/implantable technologies and point-of-care testing platforms. The review also identifies challenges and limitations, such as interference from other saliva components and the need for improved stability and reproducibility. Future prospects include the development of novel microfluidic devices, advanced materials and user-friendly diagnostic devices to unlock the full potential of saliva-based electrochemical sensing in clinical practice.

Abstract

Purpose

China’s population is ageing. Continuing care retirement communities (CCRCs) are an emerging living arrangement of older Chinese. Incorporating social sustainability features into CCRCs helps to create age-friendly residential environments for residents. However, it is still unclear what kinds of social sustainability features are incorporated into the residential environments of CCRCs in China. Therefore, this study aims to address this research gap.

Design/methodology/approach

Qualitative content analysis is adopted to analyse the retrieved business information of representative CCRC developers in China.

Findings

This study revealed 36 social sustainability features in CCRCs, with the top-ranked ones being health care and management, social connection and engagement, high-quality and diverse services and daily life support and assistance. Additionally, a preliminary social sustainability framework of CCRCs was proposed, and this framework includes the five components of care and health, environment and management, service and facility, age-friendly life philosophy and social support and inclusion.

Originality/value

In theory, this research’s findings clarify the meaning of social sustainability within the context of CCRCs, which supports future relevant explorations in the CCRC research community. In practice, these findings enhance stakeholders’ understanding of the social sustainability in CCRCs, which promotes the development of age-friendly living environments for older people in an ageing society.
