Special Issue Information

Dear Colleagues,

Over the last decade, analytical chemistry has been taking advantage of mobile micro- and nanodevices for sensing target molecules and biomolecules. Self-propelled micro/nanomotors, capable of converting diverse energy sources into effective movement, have emerged as an alternative tool in the sensing field due to (i) the enhanced reactivity associated with the micromixing effect, (ii) their functional versatility, (iii) capacity of transporting, and (iv) isolation of target molecules in complex media. These advantages have prompted short-time analysis and greater sensitivity in different bioassay formats.

We invite manuscripts for this forthcoming Special Issue entitled “Micro- and Nanomotors for Sensing”, in all aspects relevant to the use of micro- and nanomotors as new sensing tools. Both reviews and original research articles are welcome.

If you have any suggestions that you would like to discuss beforehand, please feel free to contact us.

We look forward to and welcome your participation in this Special Issue.

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. Sensors is an international peer-reviewed open access semimonthly 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 2600 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.

Bacterial biohybrid microswimmers aim at exploiting the inherent motion capabilities of bacteria (carriers) to transport objects (cargoes) at the microscale. One of the most desired properties of microswimmers is their ability to communicate with their immediate environment by processing the information and producing a useful response. Indeed, bacteria are naturally equipped with such communication skills. Hereby, two-component systems (TCSs) represent the key signal transducing machinery and enable bacteria to sense and respond to a variety of stimuli. We engineered a natural microswimmer based on the Gram-positive model bacterium Bacillus subtilis for the development of biohybrids with sensing abilities. B. subtilis naturally adhered to silica particles, giving rise to different motile biohybrids systems with variable ratios of carrier(s)-to-cargo(es). Genetically engineered TCS pathways allowed us to couple the binding to the inert particles with signaling the presence of antibiotics in their surroundings. Activation of the antibiotic-induced TCSs resulted in fluorescent bacterial carriers as a response readout. We demonstrate that the genetically engineered TCS-mediated signaling capabilities of B. subtilis allow for the custom design of bacterial hybrid microswimmers able to sense and signal the presence of target molecules in the environment. The generally recognized as safe (GRAS) status of B. subtilis makes it a promising candidate for human-related applications of these novel biohybrids. Full article
