Optical Tweezers: Preparing Samples for RBC Trapping

AI Thread Summary
The discussion centers on the challenges of preparing samples for trapping red blood cells (RBCs) using optical tweezers. The original poster expresses concern about potential mistakes in their sample preparation method. They mention using a diluted blood sample mixed with phosphate-buffered saline (PBS) and distilled water but are experiencing issues with the RBCs not flipping. Suggestions include conducting a Google search for relevant articles on optical tweezers and trapping RBCs, with one specific article from Nature Communications being highlighted as a useful resource. The conversation also touches on the effectiveness of the optical trap with microspheres, indicating prior successful work with them.

I am currently working on project for trapping RBC's using optical tweezers but i think i am making a mistake in preparing the sample. Can anyone provide an appropriate sample preparing method ?

I did a Google search on optical tweezers for trapping red blood cells, and got lots of good hits. This was the first article on the list:

Maybe try doing that search, to see if you find what you need. :smile:

Does your trap work on microspheres? Do you have a dilute suspension of RBCs?

yes sir i do have worked on microspheres and i do have diluted blood with 1/2ml PBS, 1/2ml distilled DI water and a drop of blood. also the RBCs are not flipping .
i have tried changing the power supplied

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
