Special Issue Information

Dear Colleagues,

This Special Issue is proposed to encourage further research and development in nanotechnologies in the field of bio-detection.

Nanotechnology is generally defined as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. It is an interdisciplinary and comprehensive research area, which involves not only the traditional micro/nano manufacturing science and technology, such as molecular beam epitaxy, high-precision lithography, ion beam milling, etc., but also the recently developed techniques of molecular tailoring and assembly to fabricate the so-called molecular devices, 2D nano-materials (like graphene), functional nucleic acid-functionalized sensing interfaces, nano/quantum-particle-enhanced biosensors, and so on.

Nanotechnology for bio-detection is one of the branches of the numerous applications of nanotechnology. Thanks to intriguing nanotechnology studies such as those on lab-on-chip, functional nanomaterials, 3D/2D nanomaterial-enhanced bio-sensing interfaces and biosensors, fast and cheaper bio-assays can be realized. This Special Issue will cover a wide range of topics related to nanotechnology in bio-detection, like nano-biomimetics-generated novel sensing strategies, graphene- or other 2D nanomaterial-based biosensors, quantum dot-constructed in vivo biosensors or bio-sensing interfaces, functional nucleic acid-based biosensors, etc.. Contributions to this Special Issue might be perspectives, reviews, or original researches.

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. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

In this work, we successfully developed a novel and sensitive gas sensor for the determination of trace acetophenone based on its cataluminescence (CTL) emission on the surface of nano-praseodymium oxide (nano-Pr6O11). The effects of working conditions such as temperature, flow rate, and detecting wavelength on the CTL sensing were investigated in detail. Under the optimized conditions, the sensor exhibited linear response to the acetophenone in the range of 15–280 mg/m3 (2.8–52 ppm), with a correlation coefficient (R2) of 0.9968 and a limit of detection (S/N = 3) of 4 mg/m3 (0.7 ppm). The selectivity of the sensor was also investigated, no or weak response to other compounds, such as alcohols (methanol, ethanol, n-propanol, iso-propanol, n-butanol), aldehyde (formaldehyde and acetaldehyde), benzenes (toluene, o-xylene, m-xylene, p-xylene), n-pentane, ethyl acetate, ammonia, carbon monoxide, carbon dioxide. Finally, the present sensor was applied to the determination of acetophenone in human exhaled breath samples. The results showed that the sensor has promising application in clinical breath analysis.
