Nanoneedles Batch Fabrication

Mechanical Ultra sensitive cantilever

(k < 0.1 mN/m, f0 > 100 KHz)

E = 84 ± 1 Gpa

Electrical Highly conductive:

comparable to platinum and copper

High current capability: 5 mA

Thermal:

Melting point: Experimentally measured: 950 ºC,

• Long term stability in air

• A thin layer of oxide forms around the nanowire and

protect the rest

Highly resistant to Reactive Ion Etching

NANOTOUCH FOR SIDEWALL SCANNING AND DEPTH MEASUREMENTS AT MICROSCALE

NaugaNeedles in collaboration with InSituTec is

developing the NanoTouch to address the gap in

metrology

Results of Sidewall Imaging Using NanoTouch

Depth Measurement Using NanoTouch

A Handheld detector to detect and capture low dose Circulating Tumor

Cell (CTC) in 1 ml of blood

Circulating tumor cells (CTC) are cells that detach from

primary tumors and circulate in the blood stream

Early detection of low counts of CTCs in patient blood

sample can be used as a valuable indicator for diagnosis

How can 1 to 10 CTCs mixed with 5 billion Red and White

blood cells be detected?

PROBLEM REGARDING DETECTION AND CAPTURING OF LOW DOSE CTC

EXAMPLE OF A MICROCHIP CTC CAPTURING DEVICE

Detection Method:

florescence

microscopy

Capturing method:

micropillar array

EXAMPLE OF A MICRO FLUIDIC DEVICE FOR CTC CAPTURING

Capturing method: microstructure array

Detection Method: florescence microscopy
