Special Issue Information

Dear Colleagues,

Over the past decade, a growing number of micro/nano biosensors have been developed to revolutionize healthcare owing to their excellent sensing performance, small size, small sample requirements, and low cost. Moreover, the gap between laboratory and industry in healthcare applications can be minimized by changing traditional laboratory instruments into novel portable devices using advanced micro/nano fabrication and modification (e.g., photolithography, sputtering, electrodeposition, spin-coating, etc.), which we believe is crucial for developing a reliable health monitoring hand-held system for self-diagnosis. The highlights of this Special Issue will mainly aim for recent developments in micro-/nano-scale biosensors as well as present cutting-edge technologies in relevant fields, including various micro/nano manufacturing processes, novel sensing platforms, nanomaterial implementation and modification, and determination concepts, which may contribute as key factors in the expansion of related studies. The scope of this Special Issue includes, but is not limited to:

  • Health monitoring using micro/nano biosensors;
  • Micro/nano scale fabrication;
  • Electrochemical, electrical, and optical-based biosensors;
  • Integration of sensors and electronics as portable sensing systems;
  • Simultaneous sensing of multiple analytes related to bodily conditions;
  • Low-cost fabrication of biosensors.

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.

The early diagnosis of acute myocardial infarction is difficult in patients with nondiagnostic characteristics. Acute myocardial infarction with chest pain is associated with increased mortality. This study developed a portable test kit based on cholesteric liquid crystals (CLCs) for the rapid detection of AMI through eye observation at home. The test kit was established on dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride-coated substrates covered by a CLC-binding antibody. Cardiac troponin I (cTnI) is a major biomarker of myocardial cellular injury in human blood. The data showed that the concentration of cTnI was related to light transmittance in a positive way. The proposed CLC test kit can be operated with a smartphone; therefore, it has high potential for use as a point-of-care device for home testing. Moreover, the CLC test kit is an effective and innovative device for the rapid testing of acute myocardial infarction-related diseases through eye observation, spectrometer, or even smartphone applications.
