Nanotechnologies are enabling novel nano-dimensional materials and devices that find diverse applications in the fields like medicine, electronics, and energy production. With the increasing awareness, healthcare is in focus that includes early diagnosis, drugs discovery, etc. For biological and chemical diagnostic sensors, specificity and sensitivity are crucial aspects. Among the various nano-materials, nanowire (NW) and carbon nano-tube (CNT) based bio-chemical sensors are most exploited for the purpose. NW and CNT sensors work on the principle of Field Effect Transistor (FET) where charge associated with the chemical and biological species attached on the nanowire/ CNT surface acts as chemical or bio-gate, and the devices are also termed as CHEM-FET or BIOFET. The paper will present the process techniques to realize highly reproducible silicon nano-wire sensors in array format for various bio-chemical applications. Some typical analysis including DNA sensing for Single Nucleotide Polymorphisms (SNP) and Heterozygous SNPs detection; analysis of various ions like H+ (pH), alkali metal ions (Ca2+, Mg2+, Na+, K+)7; Cu2+, Zn2+; bio-electricity detection from cells and organs, etc. will be presented.
