# Smartphone platform detects Alzheimer’s biomarker amyloid-β 2026-08-25T18:06:29+00:00 | Health & Science | Indian Opinion Desk Corroboration: 2 independent outlets Scientists at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have developed a smartphone-enabled platform, ADxFluor, that detects amyloid-β (Aβ), a key biomarker for Alzheimer's disease. The platform uses a fluorescence-responsive molecule called TZ-48, which changes fluorescence intensity upon interacting with Aβ. A dedicated smartphone app captures and quantifies these changes, enabling rapid and user-friendly detection. According to a study published in the journal ACS Chemical Neuroscience, TZ-48 shows high selectivity and sensitivity for Aβ fibrils, and can label plaques in transgenic mouse brains. The ADxFluor platform also allows detection of Aβ in cerebrospinal fluid and blood serum, accurately distinguishing diseased from healthy mice in lab tests. The researchers, led by Thimmaiah Govindaraju, say the system offers a low-cost, portable alternative to expensive PET and MRI scans for Alzheimer's screening and staging. ## Indian Opinion Analysis Both sources report the scientific development neutrally, with greaterkashmir.com providing more technical detail on the research methodology and the limitations of existing diagnostics. The Economic Times health edition focuses on the practical application and the smartphone aspect, presenting the tool as a promising alternative. Neither source adopts a government-critical or pro-government stance, the coverage is straightforward reporting of a scientific advance. The broader implication is that portable diagnostic tools could reduce the cost barrier for Alzheimer's screening in India, where access to PET scanners remains limited. The next step would be human clinical trials to validate the platform for routine use.
