Overview

In order to achieve the application of our engineered bacteria in practise, we designed the expired drugs recycling and degrading device (Drug Avenger) and the fluorescence detection device.

Expired drugs recycling and degrading device (Drug Avenger) was used to recycle expired drugs. The modular design allowed for the recovery of three types of drugs. Fig. 2. and animation show the design and theoretical ideas.

In this project,the fluorescence detection device was used to specifically detect the CIP concentration, and it was assembled by a switching power supply, water pumps, acquisition card, photodetector, and an external device.

Device iteration

In the development process of hardware, our detection device module had been updated three iderations, and finally the third generation version was designed and realized.

logoFirst generation device

The first generation of detection modules consists of photodetectors, laser sources, STM32 Development board, pumps, filters, lenses, and external devices. The collected beam was vertical with the incident beam.

logoSecond generation device

After discussing with several professiors, we found that the first-generation device was not efficient in fluorescence excitation, and some details were unreasonable ,it can not meet the requirements and cost of 3D printing technology.So the second-generation device optimized the optical path based on the first-generation device in which no transparent parts were needed. The measuement angle was fixed at 45° angle to enhance fluorescence excitation efficiency.

We tried the second generation device and found that it was not stable enough to detect the weak fluorescence. Under the guidance of Dr.Gul, we improved the original device in the fixation of the engineering bacteria, and designed the funnel-shaped groove, which was conducive to the accumulation of engineering bacteria and also improve the stability of the detection fluorescent signal.
