Background

Bacteria-associated infections are prevalent in our society, which can cause high mortality rates and pose a significant threat to public health. The conservative treatment of such infections using antibiotics often results in antibiotic resistance that further exacerbates the existing bacteria-associated public health problem. Additionally, bacteria associated with infections often grow as inherently resistant biofilms, e.g., on implant surfaces, that can only be treated if detected as early as possible. However, limited accessibility of reliable diagnostic tools remains challenging, particularly in low-income settings. Classical methods used for pathogen detection are time-consuming costly, and require specialized technical facilities as well as expert personnel to handle the samples. Over the next decade, we expect antimicrobial resistance cases and biofilm-associated infections to increase, thus multiplying the number of public health issues.

It is of paramount importance to develop novel, reliable point-of-care diagnostic setups to detect and identify pathogenic bacteria to find the right course of treatment and adapt to the development of the disease. Specifically, there is a need for devices that embody the recommended WHO guidelines in the development of diagnostic tools according to the ASSURED criteria (A- affordable, S- sensitive, S- specific, U- user-friendly, R- rapid and robust, E- equipment-free or simple, D- deliverable to end users). Thus, this Research Topic aims to cover existing and emerging sensor technologies, including in vitro and in vivo models, for their evaluation that could aid in the rapid detection and diagnosis of bacterial-associated infections.

We encourage submissions with a focus on the development and implementation of techniques and detection tools for bacterial-based infections. This includes methods and protocols for sample collection, purification, and isolation (microfluidics, lateral flow, paper-based), their comparison to conventional methods, development and testing of methods (photonics, electrochemical, biochemical, molecular and synthetic biology-based), as well as design and development of whole devices in the form of compact platforms (e.g. lab-on-a-chip). Research on software development for data acquisition and analysis will also be highly interesting. Investigations on in vitro and in vivo models to study infection-related scenarios are also welcome.

In summary, we invite submissions that cover aspects of method development, hardware and software tools, or combinations thereof, enabling engineering technologies to be applied to bacteria detection. These submissions may also include the use of additive manufacturing or other diagnostic chip technologies, which may be combined into “systems” using smartphones, wireless technology, IoT, and artificial intelligence for enabling diagnostics decision support.

Topic editors

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

     

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

     

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

  • If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor. This provides you with valuable editorial experience, improving your ability to critically evaluate research articles and enhancing your understanding of the quality standards and requirements for scientific publishing, as well as the opportunity to discover new research in your field, and expand your professional network.

  • Yes, certificates can be issued on request. We are happy to provide a certificate for your contribution to editing a successful Research Topic.

  • Research Topics thrive on collaboration and their multi-disciplinary approach around emerging, cutting-edge themes, attract leading researchers from all over the world.

  • As a topic editor, you can set the timeline for your Research Topic, and we will work with you at your pace. Typically, Research Topics are online and open for submissions within a few weeks and remain open for participation for 6 – 12 months. Individual articles within a Research Topic are published as soon as they are ready.
