SERCO, finally! "The Biggest Company You Never Heard Of". My Sandy Hook research lead to me down this trail. Have a look-see at what camera's they have access to.

Isn't Prince William involved in SERCO?

In short, light reflected off of colored construction paper is passed through a sample and detected by an RGB application on a smartphone.
The researchers engineered quantum dot barcoded microbeads and a secondary label to search for antibodies against COVID-19 antigen in the patient's blood. Finding the antibodies leads to a change in microbead emission color.
The beads are then loaded into the device, 'activated' with a laser, and the signal is imaged using a smartphone camera. An app is designed to process the image to identify the bead's emission change. Lastly, the data are interpreted and transmitted remotely across the world for data collection and decision making.
"The beauty of the system is that everything is integrated into one portable unit." said Zhang.
This technology, by which quantum dot microbead detection can measure minuscule amounts of key biomarkers in blood, has been in development for the past 10 years.

An ionic liquid (IL) is a salt in the liquid state. In some contexts, the term has been restricted to salts whose melting point is below some arbitrary temperature, such as 100 °C (212 °F). While ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules, ionic liquids are largely made of ions.
Ionic liquids have many potential applications. They are powerful solvents and can be used as electrolytes. Salts that are liquid at near-ambient temperature are important for electric battery applications, and have been considered as sealants due to their very low vapor pressure.
Any salt that melts without decomposing or vaporizing usually yields an ionic liquid. Sodium chloride (NaCl), for example, melts at 801 °C (1,474 °F) into a liquid that consists largely of sodium cations (Na+
) and chloride anions (Cl−
). Conversely, when an ionic liquid is cooled, it often forms an ionic solid—which may be either crystalline or glassy.
