The 16 s rRNA sequencing revealed the variations in the microbial communities in response to ZVI and Se, which the magnetic separation could potentially mitigate in the long term. This study provides a novel technique to achieve in-situ Se remediation and recovery by combining ZVI reduction and magnetic separation.
Immobilization of bacteriophages onto solid supports such as magnetic particles has demonstrated ultralow detection limits as biosensors for the separation and detection of their host bacteria.

Immobilization of bacteriophages onto solid supports such as magnetic particles has demonstrated ultralow detection limits as biosensors for the separation and detection of their host bacteria.
The main mechanisms were as follows: (1) The significant dissociation of Fe 3 O 4 from non-magnetic impurities and the transformation of Cu and Zn to ferrite were promoted by ball milling. (2) The separation efficiency of weak magnetic ferrite and Fe 3 O 4 was improved by cascade magnetic separation. Therefore, the proposed strategy …

Prior to magnetic separation, cells were prestained using nucleic acid DAPI dye and after cell trapping inside the microchambers, captured cells were washed two times with PBS (with the flow rate of 2 µL min −1) to ensure the elution of the nonmagnetic labeled cells. Followed by this step side magnets were removed and PBS back-flow …
