We proposed silicon nitride MZI sensor architecture as integrated biosensor for point-of-care device. This biosensor detects virus and biomolecules fast and is cost-effective. Our simulated analysis determines optimized waveguide geometry that maximizes the bulk sensitivity. MZI utilizes the refractive index of different cancer cells (1.39–1.401) to determine the waveguide bulk sensitivity .
The absorption of cancer cells at three wavelengths 1563?nm, 1573?nm, and 1579?nm offers high detection rate compared with the standard rib waveguide. The silicon nitride-based waveguide biosensor may be fabricated using CMOS E-beam lithography, and its stability will be matched to the simulated results. The proposed biosensor can provide test results in a short time than the conventional biopsy, which takes two days to detect cancer cells.
The silicon nitride (Si3N4) filtering membrane was fabricated via the standard microfabrication technology, which can be easily scaled up to mass-production. 6 µm was determined as the optimum width of the filtering pores to better separate CTCs in whole blood, which can reach a high capture efficiency of ~96%.
examples of their medical applications that relate to spinal, orthopedic and dental implants, bone grafts and scaffolds, platforms for intelligent synthetic neural circuits, antibacterial and antiviral particles and coatings, optical biosensors, and nano-photonic waveguides for sophisticated medical diagnostic devices are all covered in the research reviewed herein. The examples provided convincingly show that silicon nitride is destined to become a leader to replace titanium and other entrenched biomaterials in many fields of medicine.
Silicon nitride, silicon carbide and diamond-like carbon as non-oxide ceramics are considered to be the new generation of materials used in hip prosthetics, particularly in the manufacture of acetabular cups, due to their excellent biocompatibility, osteointegration, and tribological and mechanical properties, but all three materials need more study. However, silicon nitride is the nearest to commercialization, through businesses such as Amedica Corp. and SyntX Technologies
