− | After | + | 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. |

Overview
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.

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.

Expectation
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.
