NaugaNeedles is proud to introduce the first commercially available NanoCantileverTM with spring constant as low as 10-5 N/m, high frequency bandwidth with resonance frequencies in the 0.02–10 MHz range, small suspended mass (femto-grams), and relatively high Q-factors (∼2–50) under ambient conditions . The NanoCantileverTM is fabricated of Ag2Ga crystalline intermetallic compound  with excellent optical properties, mechanical flexibility and chemical stability in ambient condition. The NanoCantilevers can be produced in variety of lengths (5 to 100 µm long) and thicknesses (100 to 300 nm thick).
Due to the crystallinity of the metallic alloy of Ag2Ga, NanoCantilevers are extremely robust and do not plastically deform even when buckled beyond 50% of their original length . Having excellent optical properties, NanoCantilevers can be seen under an optical microscope (Figure A) and their vibration spectra can be detected by standard instroments (e.g. using a MSA-500 Micro System Analyzer from Polytec Inc , or SIOS-interferometer & vibrometer from PiezoSystemJena Inc , or custom made noninterferometric optical setup ). Figure (C) Shows the vibration spectrum of a NanoCantilever (Shown in Figure B) using a Laser Doppler Vibrometer (LDV) form Polytec.
The Young's modulus of the material has been measured at 84GPa  making the utility of NanoCantilevers ideal for ultrasmall mass sensing and high frequency bandwidth pico-Newton force detection, [1, 6] .
