Special Issue Information

Dear Colleagues,

Small colloidal particles, also known as quantum dots (QDs), have recently emerged as efficient elements for developing biosensors due to their unique optical properties. Due to their emission spectra being tunable over a wide range of wavelengths, QDs can serve as versatile components for specific/non-specific biorecognition sensors. Targeted biological elements (antibodies, proteins, peptides, aptamers, nucleic acids, small molecules, liposomes, lectins, and monosaccharides) could be tied covalently or electrostatically. Other characteristic features, like a great quantum yield, photostability, and a high fluorescence lifetime, make them ideal luminophores for aggregation-induced emission (AIE), fluorescence resonance energy transfer (FRET)-based single-molecule-detection (SMD) biosensors. The integration of QDs with SMD techniques has led to recent advancements in affluent in vivo sensing and disease diagnosis. In this regard, biocompatible semiconductor QDs are considered promising candidates for fluorescent, bioluminescent, chemiluminescent, and photoelectrochemical biosensors, as they do not use heavy metals as conventional labeling agents. Therefore, further improved QD-based sensors could be effective tools for valuable disease prognosis, biomedical research, and drug discovery in the future.

In this Special Issue, we welcome original research papers, comprehensive review articles, letters discussing new QDs formulation techniques and their applications as in vivo and in vitro biosensors for the early diagnosis of fatal diseases such as cancer, viral, genetic mutations, SARS, etc.

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. Biosensors is an international peer-reviewed open access monthly 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 2700 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.
