A nanomaterial-based breath test for short-term follow-up after lung tumor resection.

Unlabelled: In this case study, we demonstrate the feasibility of nanomaterial-based sensors for identifying the breath-print of early-stage lung cancer (LC) and for short-term follow-up after LC-resection. Breath samples were collected from a small patient cohort prior to and after lung resection. Gas-chromatography/mass-spectrometry showed that five volatile organic compounds were significantly reduced after LC surgery.

Gold nanoparticle sensors for detecting chronic kidney disease and disease progression.

Aim: To study the feasibility of a novel nanomedical method that utilizes breath testing for identifying chronic kidney disease (CKD) and disease progression.

Materials & Methods: Exhaled breath samples were collected from 62 volunteers. The breath samples were analyzed using sensors based on organically functionalized gold nanoparticles, combined with support vector machine analysis.

Classification of breast cancer precursors through exhaled breath.

Certain benign breast diseases are considered to be precursors of invasive breast cancer. Currently available techniques for diagnosing benign breast conditions lack accuracy. The purpose of this study was to deliver a proof-of-concept for a novel method that is based on breath testing to identify breast cancer precursors.
