Scope and Objectives

Objective # 1: Design and develop sensitive ultrasound detector with light.

Objective # 2: Design and develop a custom design optical tweezer and a photoacoustic tomographic microscope for diagnosing RBC.

Objective # 3: In-vivo spectral data acquisition for intrinsic various parameters estimation for RBC .

Deliverables

Develop high frequency (>50MHz) low noise ultrasound detector with light.

A prototype photo-acoustic model system for diagnosing red blood cell direct from blood vessel in infant mouse model.

Scientific Output

Developed low frequency ultrasound detector with light.

developed a prototype micro-fluidic channel with dielectric bead inside it to mimicking blood vessels and ref blood cell in it.

Developed a photo-acoustic model system for diagnosing micron size particle. Later stage the micro-fluidic channels will be replaced with infant mouse blood vessels.

Results and outcome till date

To diagnose the RBC in the live subject, we have developed a prototype system which facilitates to hold or arrest the 8-7 micron size dielectric bead (similar to RBC) in aqueous solution. Now we are optimising the system using dielectric particle ( similar to RBC) in micro-fluidic channel to mimicking the micron size blood vessel. we have detected upto 10MHz acoustic signal in aqueous medium with open light beam and now translating it to optical fiber.

Societal benefit and impact anticipated

Final aim is to diagnose red blood cell non-invasively for infant

Next steps

Making set up for generating above 10MHz (Central frequency) and large bandwidth acoustic signal and preparing testing unit for detecting high frequency acoustic signal using optical fiber tips based acoustic sensor. This sensor will be integrated with the prototype photo acoustic system to detect high frequency acoustic signals from micron size bead and red blood cells.

Challenges faced

we have successfully detected 10MHz (bandwidth limited) in open light beam though we are struggling with optical fiber based optical fringe separation when the the medium is exposed with 2.2MHz and 10MHz frequency acoustic signals.
