Special Issue Information

Dear Colleagues,

The objective of this Special Issue is to provide an overview of the state-of-the-art, results, and latest advances in research and technological developments on silicon nanowire-based sensors.

Silicon nanowires provide unique advantages for developing sensors in several respects. In particular, they can act as potential functional probes due to their unique properties. Their one-dimensional structure offers the smallest confinement for carrier transport along the longitudinal direction, and their high surface-to-volume ratio can promote detection phenomena to improve sensitivity. Silicon material offers compatibility for surface functionalization and is compatible with gas or liquid media. Then, the use of silicon nanowires as sensitive units offers large application areas covering mechanical probing, gas detection, chemical sensing, bio-elements recognition, dosing, and microfluidic integration.

Sensors based on silicon nanowires benefit from advanced research trends, especially for the development of new fabrication technologies for integration into the CMOS platform, and for sensing functions’ compatibility with low-cost technologies on various substrates, including flexible substrates.

The issue will cover topics related to chemical, biological, gas, and micromechanical sensors based on either electrical, optical or electro/micromechanical detection methods, and their latest technological advancements to increase their performances and reliability.

Gas-phase etching and optical lithography were employed for the fabrication of a silicon nanoribbon chip (Si-NR chip). The quality of the so-fabricated silicon nanoribbons (Si-NRs) was monitored by optical Raman scattering spectroscopy. It was demonstrated that the structures of the Si-NRs were virtually defect-free, meaning they could be used for highly sensitive detection of biological macromolecules. The Si-NR chips were then used for the highly sensitive nanoelectronics detection of DNA oligonucleotides (oDNAs), which represent synthetic analogs of 106a-5p microRNA (miR-106a-5p), associated with the development of autism spectrum disorders in children. The specificity of the analysis was attained by the sensitization of the Si-NR chip sur-face by covalent immobilization of oDNA probes, whose nucleotide sequence was complementary to the known sequence of miR-106a-5p. The use of the Si-NR chip was demonstrated to al-low for the rapid label-free real-time detection of oDNA at ultra-low (~10−17 M) concentrations. Full article

Impedance sensing with silicon nanowire field-effect transistors (SiNW-FETs) shows considerable potential for label-free detection of biomolecules. With this technique, it might be possible to overcome the Debye-screening limitation, a major problem of the classical potentiometric readout. We employed an electronic circuit model in Simulation Program with Integrated Circuit Emphasis (SPICE) for SiNW-FETs to perform impedimetric measurements through SPICE simulations and quantitatively evaluate influences of various device parameters to the transfer function of the devices. Furthermore, we investigated how biomolecule binding to the surface of SiNW-FETs is influencing the impedance spectra. Based on mathematical analysis and simulation results, we proposed methods that could improve the impedimetric readout of SiNW-FET biosensors and make it more explicable. Full article
