Special Issue Information

Dear Colleagues,

A transducer is a device that converts energy from one form to another. In the case of biosensors, a transducer device converts biochemical interactions occurring at the transducer interface into a readable signal. A wide range of transducer principles has been developed and used for detection of biomolecular interactions in the last few decades, looking to achieve higher sensitivities that could satisfy the continuous demanding requirements to detect low concentrations and small molecules. The development of highly sensitive transducers and biosensors offers a powerful opportunity in early diagnosis and treatment of diseases, reducing the cost of patient care associated with advanced stages of diseases.

The aim of this Special Issue is to report recent developments and advances in the design, simulation and fabrication of highly sensitive transducers for biosensing applications. It is envisaged that this will cover a wide range of areas, including electrochemical, nanomechanical, piezoelectric, piezorresistive or optical (photonic and plasmonic) transducers, combined with enzymes, antibodies, DNA, aptamers, or molecularly imprinted polymers for the specific detection of the desired analite.

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.

Liquid crystal biosensors are based on changes in the orientation of liquid crystal molecules induced by specific bonding events of biomolecules. These biosensors are expected to serve as a promising system to detect biomolecules, biomolecular activity, and even small chemical molecules because they are inexpensive, sensitive, simple, effective, and portable. Herein, we introduce the principle and fabrication of liquid crystal biosensors and review the research progress in signal-amplified technology for liquid crystal sensing and its application in the detection of viruses, bacteria, proteins, nucleic acids, and small chemical molecules. In addition, the current theoretical and practical issues related to liquid crystal biosensors were investigated. Full article
