With the development of Scanning Near Field Optical Microscopy (SNOM), optical fiber nanoprobe has made great progress in some novel application fields including Skin Cancer imaging. Nano optical fiber probe is a powerful tool for small and nanometric object imaging. However, its cost is rather high and the probability to create optical fiber nanoprobe in great quantity has not been realised, which is a disadvantage to commercial applications of the nanoprobe.


In this experiment, the Hydro mechanical etching method is proposed, and the desirable tips are created. In this method, fiber firstly is dipped into acetone to remove the jacket. Next, the tip can be etched in Hydro Fluoric (HF) solution through some mechanical arrangement to create the nanoprobe. Based on the etching mechanisms, the tip can be dipped into HF solution repeatedly if a nanoprobe is not realized last etching. When the nanoprobe is obtained, it is coated with aluminum by vapour deposition technique. Finally, data can be collected by the nanoprobe sensitively, which possibly benefit the fluorescent spectral detection of micro and nano-sample. The technique adopted is very simple, completely homemade and handmade, the etching rate is high and obviously low cost.

Scalability and Impact:

The applicability of Optical fiber probe as a real-time in-situ probe is increasing very fast with the enhancement of medical imaging techniques like Optical Coherence Tomography (OCT) and its mostly related with Florescence Microscope hence the implementation of new and simple technique is precisely a prolific step towards the improvement of this technology, we proposed to make Atomic Force Microscope’s (AFM) tips in this technique in future which presently we hire from abroad with higher cost. After completing his Masters (M.Sc) in Biomedical Instrumentation he has started his research career at his home university, University of Calcutta but shifted to Jadavpur University. He is presently working under the Joint Guidance of Dr. Sankar Narayan Patra, Asst. Prof, Dept. of Instrumentation Science & Dr. Dipankar Mondal, Asst. Prof, Dept. of Physics on Biomedical device fabrication.
