Background

Photodynamic therapy (PDT) has emerged as a promising minimally invasive treatment modality in cancer therapy, combining photosensitizers, light, and oxygen to generate cytotoxic reactive oxygen species. Despite its proven efficacy, the clinical translation of PDT faces several challenges, including poor solubility of photosensitizers, nonspecific distribution, and limited tumor penetration. Traditional photosensitizer delivery methods often result in suboptimal biodistribution, poor pharmacokinetics, and potential damage to healthy tissues. Recent advances in nanotechnology and targeting strategies have opened new possibilities for enhancing PDT efficacy through improved delivery systems and active targeting approaches. The development of sophisticated nanocarriers, including liposomes, polymeric nanoparticles, and hybrid systems, has demonstrated potential in overcoming these limitations. Additionally, the integration of active targeting moieties has shown promise in enhancing tumor specificity and cellular uptake, leading to improved therapeutic outcomes while minimizing side effects in cancer treatment.





Goal:





This Research Topic aims to explore and advance the development of novel delivery systems and targeting strategies for PDT in cancer treatment. The focus will be on innovative approaches that enhance photosensitizer delivery, improve tumor specificity, and increase therapeutic efficiency. We seek to address critical challenges in PDT delivery, including optimization of nanocarrier designs, development of smart delivery systems responsive to tumor microenvironment, and integration of active targeting moieties. Recent advances in areas such as stimulus-responsive nanoplatforms, tumor-specific targeting ligands, and multimodal therapy combinations will be explored to establish more effective PDT approaches. Particular emphasis will be placed on understanding the relationship between delivery system properties and therapeutic outcomes, including aspects such as particle size, surface chemistry, and targeting efficiency. The development of novel targeting strategies, including the use of antibodies, peptides, aptamers, and small molecules, will be investigated to enhance tumor-specific accumulation and cellular internalization of photosensitizers. Additionally, the potential of smart delivery systems that respond to specific tumor microenvironment signals or external stimuli will be explored to achieve controlled and site-specific photosensitizer release. The ultimate goal is to bridge the gap between laboratory developments and clinical applications in targeted PDT delivery systems, focusing on translational aspects and practical considerations for clinical implementation.

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.
