**4. Conclusion**

In this capture, we have reviewed the synthesis of nanowires using GLAD and their applications. We have showed that GLAD is a simple, cost effective, and catalytic free technique where well-defined vertically aligned nanostructures can be synthesized which cannot be achieved easily by nanolithography-based method, solution-based method, vapor-based methods, template-based methods. Nanowires synthesized by GLAD technique has the following advantages: Growth of vertically aligned nanostructure, the shadowing effect introduces self-alignment effect, the porosity of the nanostructure film can be controlled by changing the incident angle. Various applications of nanowire and axial heterostructure nanowire array-based photodetectors as well as wettability applications synthesized using the GLAD technique have been discussed. The performance of these applications can be improved further with different structural and growth parameters. Therefore, it can be concluded that these nanoscale-based applications have potential for future industrial and commercial applications.
