Special Issue Information

Dear Colleagues,

The fusion of biotechnology, nanotechnology, and electronics has emerged as an important research field in the past decade. Nanomaterial, with the tiny size (1–100 nm) and extraordinary properties different from the bulk form, is providing a powerful platform to generate breakthroughs for addressing the challenges in healthcare, energy, environment, and electronics. Nanomaterial based biosensors (nano-biosensors) represents a highly interdisciplinary research field that includes biology, chemistry, optics, and physics. Nanomaterials can be surface functionalized with different biomolecules, offering us an ideal template to discover new reaction processes and detection regimes. Analytes can be more specifically captured by the nanosensors due to the large surface area to volume ratio of nanomaterials that can enhance the detection accuracy and sensitivity.

This Special Issue aims to highlight the current progress, challenges, and applications of the nano-biosensors development. Potential topics include, but are not limited to:

  • Nanostructured materials;
  • Functional materials;
  • Bio-inspired materials;
  • Nanoelectronics;
  • Biophotonics;
  • Stretchable electronics;
  • Microfluidic systems.

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. Micromachines 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 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.

Abstract
In this paper, silver nanoparticles (AgNPs) were successfully green-synthesized for the first time using Hedysarum polysaccharide (HPS) as a reducing agent, stabilizer, and modifier (HPS-AgNP). Thiamazole could induce the aggregation of HPS-AgNPs in the residue on a cellulose membrane. A syringe paper-based analytical [...] Read more.
In this paper, silver nanoparticles (AgNPs) were successfully green-synthesized for the first time using Hedysarum polysaccharide (HPS) as a reducing agent, stabilizer, and modifier (HPS-AgNP). Thiamazole could induce the aggregation of HPS-AgNPs in the residue on a cellulose membrane. A syringe paper-based analytical device was creatively established to ensure the tightness, stability, and good repeatability of the test. The color information remaining on the cellulose membrane was converted into gray values using ImageJ software. Hence, the linear regression curve for thiamazole was established as y = 1 + 0.179x with a detection limit (LOD) of 24.6 nM in the relatively wide range of 0.1~10 μM. This syringe paper-based analytical device was successfully applied to the biological samples. Full article
