This paper demonstrates that the gas-filled compartments in the packing material commonly
called “bubble wrap” can be repurposed in resource-limited regions as containers to store
liquid samples, and to perform bioanalyses. The bubbles of bubble wrap are easily filled by
injecting the samples into them using a syringe with a needle or a pipet tip, and then sealing
the hole with nail hardener. The bubbles are transparent in the visible range of the spectrum,
and can be used as “cuvettes” for absorbance and fluorescence measurements. The …
