This involved coding for the machine, circuit design and mechanical framing of the assembly of an antibiotic finder for cultured bacteria to detect urine samples. Three different mechanisms were designed. The coding was done on arduino and required the use of various interfaces with sensors, stepper motors, handling interrupts etc. My job was also to come up with an algorithm based on prior data given to generate a formula for Tubidity of the urine essay given. It involved finding similarity between given data 


A point-of-care device for testing antibiotic sensitivity of pathogens found in human urinary tract: The developed device offers

a) Ease of operation and analysis of results

b) rapid results at the bedside or in doctors chambers/lab in less than two hours

c) reliability comparable to conventional disc assay for antibiotic sensitivity of pathogens

d) Affordable low cost per test.  


UTI alone leads to more than 8 million office visits and over a million hospitalizations each year in USA alone.  The device provides for growth of pathogens in a specially designed medium ensuring rapid growth with release of a product linearly related to the number of bacteria present.  In the instance of the bacteria being sensitive to any given antibiotic the chromogen is not released.  The released chromogen is read out using a specially fabricated readout-machine, based on a color to frequency conversion, giving both an alphanumeric display on a screen and a print out for permanent record of the report.  The preloaded antibiotic panel comes in two sets and allows for screening fourteen antibiotics with provision for seven more.
