Multimodal Nano-DESI Mass Spectrometry Imaging Reveals Phospholipids Accumulation in and around Amyloid Plaques in Alzheimer’s Disease Alzheimer’s disease (AD), characterized by β-amyloid plaques, is increasingly recognized by lipid dysregulation as a key factor in its pathology. Mass spectrometry imaging (MSI), a powerful tool for m...

Excited to share our latest paper in ACS Chemical Neuroscience, in which high-resolution nano-DESI imaging is used to study lipid accumulation around the plaques in an Alzheimer's disease mouse model.

Amina Woods Obituary - Visitation & Funeral Information Share Memories of Amina & Support the Woods Family

Saddened to share the news that Amina Woods passed away on March 31. Amina was an outstanding scientist who consistently challenged conventional thinking in her field. She inspired many of us through her work and will be deeply missed.

Check out the latest editorial article in #IJMS, highlighting two exciting perspective articles by Ian Webb and Ahmed Hamid in the Young Scientist Feature collection.

Check out our latest paper on isomer-selective lipid imaging using a singlet oxygen reaction with C=C bonds. We describe a universal photosensitizer compatible with both positive and negative ionization modes. Congrats to Sara Amer and co-authors!
