Special Issue Information
Dear Colleagues,
The state of the art in optical imaging and nanosensing for single nanoparticles and cellular organelles has made significant strides in recent years, with advancements in techniques like super-resolution microscopy, fluorescence imaging, and nanoparticle-based sensors, including a variety of plasmonic methods and nanopore approaches. Super-resolution microscopy methods, such as STORM (stochastic optical reconstruction microscopy) and PALM (photoactivated localization microscopy), have achieved unprecedented spatial resolution, allowing the visualization of cellular structures at the nanometer scale, yet their full potential in the analysis of lipid nanoparticles, viruses used for gene therapy, exosomes, and cellular organelles has not been fully exploited to date. The limited ability to monitor complex, dynamic interactions inside nanoparticles and cellular organelles over extended periods also remains a bottleneck, as current methods often struggle with photobleaching or phototoxicity. Therefore, methods to improve fluorescence-mediated sensing or perform label-free measurements with techniques like SPR (surface plasmon resonance), SERS (surface-enhanced Raman spectroscopy), and electrical nanopore sensing are still needed. Furthermore, the integration of multimodal imaging systems that combine optical techniques with other complementary methods, such as electron microscopy, atomic force microscopy, or mass spectrometry, is still in its early stages and requires refinement to improve data interpretation and accuracy. Addressing these challenges will be crucial to fully realize the potential of optical imaging and nanosensing in both basic and applied biological research focused on the analysis of molecular interactions between and within diverse types of nanoparticles and cellular organelles.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Bioengineering is an international peer-reviewed open access monthly journal published by MDPI.
