Spectrometric data format

Targeted biological samples

For our project, we aim to target one of the most accessible human bodily fluids:

  • Sweat
    • Still difficult to use as it is difficult to collect a quantity large enough
    • Reliable collection a problem too
  • Sperm
    • very socially awkward - many cultural, religious issues associated
  • Breast Milk
    • Same social issues as above, to a lesser extent maybe
    • Limited 'Market': lactating women only
  • Saliva
    • Few practical collection problems
    • 23andME
    • Saliva Analysis is used to detect the level of hormones or drugs. But there is little a spectrophotometer can do to help (no correlation between a health issue and opacity, color or any such criterion).
  • Blood
    • Also Practical, although collection a bit harder
    • Anyone got a link to a 23andMe-like project?
    • Spectrophotometry may be of limited use, but of use nonetheless.
    • To know more about Blood Analysis
  • Urine
    • Also practical
    • Anyone got a link to a 23andMe-like project?
    • This is the bodily fluid for which spectrophotometry may be of most use.
    • To know more about Urine Analysis


NB: There are also some internal bodily fluids (but they are not practical to use), including

  • cerebrospinal fluid surrounding the brain and the spinal cord
  • synovial fluid surrounding bone joints
  • intracellular fluid is the fluid inside cells
  • aqueous humour and vitreous humour the fluids in the eyeball.

A full (and very long) list of the human bodily fluids can be found on Wikipedia

Open Dataset Repository design

Data visualisation

  • Processing-based

Data Analysis

  • Data Analysis will play an important role in the second part of the project , that is the construction of the Web 2.0 Service
  • More on our apporach to data analysis can be found on Data Analysis
