Dear Colleagues,

I am guest editing a Special Issue titled "Conjugated Polymers for Bioimaging Applications". In this Issue, I would like to present new results on the synthesis, preparation, physicochemical properties, and bioimaging applications of ultraviolet, visible, and near infrared (NIR) π-conjugated polymers, especially in the form of aqueous nanoparticles, the so-called conjugated polymer nanoparticles (CPNs), which have emerged as horizon nanomaterials for optical imaging. Special attention will be focussed on two aspects. The first aspect will cover the synthesis of new NIR conjugated polymers, along with new strategies to impart colloidal stability in water, such as nanoprecipitation, encapsulation, and functionalization, with hydrophilic groups, as well as their structural determination. The second aspect will cover new results on their in vitro and in vivo characterization as optical contrast agents, upon laser excitation, for optical imaging (fluorescence or photoacoustic response) in the ultraviolet, visible, and near infrared (700–1500 nm) wavelength parts of the electromagnetic spectrum.

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. Electronic Materials is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
