Nanoparticles are being used more frequently in biological research and present unique hazards. Nanoparticles are 1-100 nm, but ultrafine particles, tubules, and fibers up to 500 nm are often included in this category.
Nanoparticles used in association with or in biological materials need to be listed on a biosafety protocol (e.g., nanoparticles administered to cells/organs). If you are using nanoparticles or nanomaterials not in conjunction with biological materials, they need to be in your chemical hygiene plan but do not need to be listed on a biosafety protocol (e.g., purified proteins, chemicals, antibodies, drug delivery). Nanoparticles used in association with biological toxins need to be listed on a biosafety protocol.
The biological material or microbe used, in conjunction with the nanoparticle or nanomaterial, will determine the biosafety level for the activities. Nanoparticles or nanomaterials alone (not associated with biological materials) will not have a biosafety level designation, so the biosafety level will be determined based on the biological work.
More information on nanoparticles may be found at https://ehs.wisc.edu/workplace-safety/occupational-health/workplace-hazards/nanomaterial-usage-in-research-guidance/.
In addition to the nanoparticle specific page in Bio-ARROW, you will need to add additional information in other sections of the biosafety protocol.

Components |
Plasmid DNA encoding a miRNA, Poly lactic-co-glycolic acid (PLGA) |
|
Preparation Steps |
Receive 100 ul of nanoparticle ready-to-use, aliquot as used. Typically, less than 10 ul is used at a time. No dilution is needed. Plasmid is added and mixed before administration to cells. No containment is needed although a BSC may be used. |

|
Components |
Nanoparticle is lipid-based and encapsulates CRISPR components including Cas9 protein (active), homology directed repair template (DNA), and guide RNA (gRNA) and it directly targets the nucleus and delivers gene editing components |
|
Preparation Steps |
Human cancer cells lines will be treated with hypotonic lysing buffer, the resulting solution will undergo three freeze-thaw cycles, and then the mixture will be centrifuged to collect the cell membranes. |
