POCT has been less common in the recent past due to a lack of portable medical devices capable of facilitating effective medical testing. However, recent growth has occurred in this field due to advances in diagnostic technologies, device miniaturization, and progress in wearable electronics. Among these developments, electrochemical sensors have attracted interest in the POCT field due to their high sensitivity, compact size, and affordability. They are used in various applications, from disease diagnosis to health status monitoring. In this paper we explore recent advancements in electrochemical sensors, the methods of fabricating them, and the various types of sensing mechanisms that can be used. Furthermore, we delve into methods for immobilizing specific biorecognition elements, including enzymes, antibodies, and aptamers, onto electrode surfaces and how these sensors are used in real-world POCT settings.</p><h3 data-test=\"abstract-sub-heading\">Graphic abstract</h3>","PeriodicalId":48627,"journal":{"name":"Bio-Design and Manufacturing","volume":"54 1","pages":""},"PeriodicalIF":7.9,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141774009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lasers have long been used to develop original solutions to such challenging technological problems due to their remote, sterile, rapid, and site-selective processing of materials. In this review, recent developments in relevant laser processes are summarized under two separate categories. First, transformative approaches, such as for laser-induced graphene, are introduced. In addition to design optimization and the alteration of a native substrate, the latest advances under a transformative approach now enable more complex material compositions and multilayer device configurations through the simultaneous transformation of heterogeneous precursors, or the sequential addition of functional layers coupled with other electronic elements. In addition, the more conventional laser techniques, such as ablation, sintering, and synthesis, can still be used to enhance the functionality of an entire system through the expansion of applicable materials and the adoption of new mechanisms. Later, various wearable device components developed through the corresponding laser processes are discussed, with an emphasis on chemical/physical sensors and energy devices. In addition, special attention is given to applications that use multiple laser sources or processes, which lay the foundation for the all-laser fabrication of wearable devices.</p><h3 data-test=\"abstract-sub-heading\">Graphic abstract</h3>\u0000","PeriodicalId":48627,"journal":{"name":"Bio-Design and Manufacturing","volume":"21 1","pages":""},"PeriodicalIF":7.9,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141773968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The growing research and utilization of novel materials in designing wearable biosensors have accelerated the development of point-of-care sensing platforms and implantable biomedical devices in human health care. Among numerous potential materials, conjugated polymers (CPs) are emerging as ideal choices for constructing high-performance wearable biosensors because of their outstanding conductive and mechanical properties. Recently, CPs have been extensively incorporated into various wearable biosensors to monitor a range of target biomolecules. However, fabricating highly reliable CP-based wearable biosensors for practical applications remains a significant challenge, necessitating novel developmental strategies for enhancing the viability of such biosensors. Accordingly, this review aims to provide consolidated scientific evidence by summarizing and evaluating recent studies focused on designing and fabricating CP-based wearable biosensors, thereby facilitating future research. Emphasizing the superior properties and benefits of CPs, this review aims to clarify their potential applicability within this field. Furthermore, the fundamentals and main components of CP-based wearable biosensors and their sensing mechanisms are discussed in detail. The recent advancements in CP nanostructures and hybridizations for improved sensing performance, along with recent innovations in next-generation wearable biosensors are highlighted.

Stretchable triboelectric nanogenerator (TENG) is a high-efficiency energy harvesting technology that converts mechanical into electrical energy, effectively powering wearable bioelectronic devices. This study comprehensively overviews recent advances in stretchable TENG for use in wearable bioelectronic devices. The working mechanism of stretchable TENG is initially explained.

Furthermore, applications of wearable bioelectronic devices based on stretchable TENG in human health monitoring (body movements, pulse, and respiration) and human–machine interaction (touch panels, machine control, and virtual reality) are introduced.
