article_snippet: According to the files, the wearable could target these cells using an 'external energy source' such as ultrasound or radio frequencies.
article_snippet: The energy used would depend on what the band is targeting, but The energy used would be designed to alter the chemical composition of the analyte. '
article_snippet: In one relevant example, certain proteins have been implicated as a partial cause of Parkinson's disease; the development of Parkinson's disease may be prevented or retarded by providing particles functionalized with a bioreceptor that will selectively bind to this target' continued the files. '
article_snippet: These bound particles may then be used, in combination with a wearable device as described above, to modify or destroy the target protein. '
article_snippet: As a further example, this target could be cancer cells; by selectively targeting and then modifying or destroying the cancer cells, the spread of cancer may be diminished.'
highlights_snippet: substances could be proteins linked with Parkinson's, or cancer cells .
  
highlights_snippet: substances would then 'modify or destroy' targets by transmitting energy into blood .
