Special Issue Information

Dear Colleagues,

Please allow us to introduce ourselves as Guess Editors of the journal Biosensors, Janire Peña, University of Houston, and Viviana Gonzalez, University of Castilla La Mancha.

Both of us have been pursuing research on nanomaterials in the area of nanobiology and environment chemistry for many years. The two of us are currently hosting a Special Issue of Biosensors entitled “Advances in Nanomaterials for Biosensing and Drug Delivery”.

Recently developed nanomaterials exhibit attractive physicochemical properties, possess versatile and tunable functionality, and have proven to be suitable and performance-enhanced candidates as bioactive nanocoatings for improved implantable and exploratory devices, nanoplatforms for specific and selective detection and imaging, nanostructures for tissue restauration and regeneration, and as nanosystems for controlled, targeted, and circumstantially triggered drug delivery.

We would like to invite you to contribute to this Special Issue with a research article on Advances in Nanomaterials for Biosensing and Drug Delivery. Furthermore, in this Special Issue, we would like to include advances in the drug delivery area. All articles will be immediately available to read and reuse upon publication.

If you have any questions, or if we can provide you with more information, please do not hesitate to contact us. We are looking forward to receiving your submissions.

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.

Supramolecular Enzymatic Labeling for Aptamer Switch-Based Electrochemical Biosensor

Abstract

Here we report a novel labeling strategy for electrochemical aptasensors based on enzymatic marking via supramolecular host–guest interactions. This approach relies on the use of an adamantane-modified target-responsive hairpin DNA aptamer as an affinity bioreceptor, and a neoglycoconjugate of β-cyclodextin (CD) covalently attached to a redox enzyme as a labeling element. As a proof of concept, an amperometric aptasensor for a carcinoembryonic antigen was assembled on screen-printed carbon electrodes modified with electrodeposited fern-like gold nanoparticles/graphene oxide and, by using a horseradish peroxidase-CD neoglycoenzyme as a biocatalytic redox label. This aptasensor was able to detect the biomarker in the concentration range from 10 pg/mL to 1 ng/mL with a high selectivity and a low detection limit of 3.1 pg/mL in human serum samples.

Recent Advances in DNA Nanotechnology-Enabled Biosensors for Virus Detection

Abstract

Virus-related infectious diseases are serious threats to humans, which makes virus detection of great importance. Traditional virus-detection methods usually suffer from low sensitivity and specificity, are time-consuming, have a high cost, etc. Recently, DNA biosensors based on DNA nanotechnology have shown great potential in virus detection. DNA nanotechnology, specifically DNA tiles and DNA aptamers, has achieved atomic precision in nanostructure construction. Exploiting the programmable nature of DNA nanostructures, researchers have developed DNA nanobiosensors that outperform traditional virus-detection methods. This paper reviews the history of DNA tiles and DNA aptamers, and it briefly describes the Baltimore classification of virology. Moreover, the advance of virus detection by using DNA nanobiosensors is discussed in detail and compared with traditional virus-detection methods. Finally, challenges faced by DNA nanobiosensors in virus detection are summarized, and a perspective on the future development of DNA nanobiosensors in virus detection is also provided. Full article
