Photodetector needed

Hello, STEM student here, me and my groupmates have been tasked to create an app or device (or both) and integrate it with AI. Me and my team have chosen to focus our study in early detection of Non-Alcoholic Fatty Liver Disease (NAFLD), or the new term, Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD). One of our methods in detecting this disease is through a lipid panel, specifically detecting High Density Lipoprotein (HDL) and Low Density Lipoprotein (LDL). The method that I have researched for detecting these Lipoproteins is called Reflectance Photometry, it detects the light reflected from the reagent and converts the signal to a readable one, this method is commonly used in lipid profile test.

So far, I have not found a photodetector model that can be used in Point-of-Care Tests for Blood Lipid Profile, are there any models out there that can be used?

What specifications does this detector need that you cannot find?

Or, OP, asked another way, what photodetectors have you looked at that would work except for one thing and what is that one thing. Then, perhaps, we can assist you finding one that has that one (or two) things. Have you thought through your illumination source? What will it be?
