In order to achieve the application of our engineered bactria 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, capture card, photodetector, and an external device.

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.

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.

During the further discussion with several professiors, we found that the first-generation device was not efficient in fluorescence excitation, and some details were unreasonable because of the requirements and cost of 3D printing technology. But the second-generation device optimized the optical path based on the first-generation device and need no more transparent parts. 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 fixed the shortcomings of 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.

Finally, we designed a community drug recycling bin and fluorescence detection device based on the third generation of detection module devices. For more detailed information on the design of community drug recycling bins and fluorescence detection devices,

In order to make other teams understand it easily and improve hardware together, we share important parameters, 3D models and acquisition software below.

designing other drug degradation modules. We have reserved some modular designs to make them much easier and more convenient to implement. We also hope to optimize the design detection module. By doing so, we can get more stable and efficient signals and implementate the device at a lower cost.
