Image: Visual determination of positive and negative samples. Examples of malaria CZC-LAMP tubes after the reaction. It is not possible to determine positive or negative under natural light due to the interference by hemoglobin (lower). However, positive samples emit green fluorescence under 505 nm blue-green light (upper) (Photo courtesy of Hokkaido University School of Medicine).

Direct Blood Dry LAMP System Detects Malaria Species

Plasmodium falciparum is thought to be the most prevalent among Plasmodium species and although this species has been well investigated epidemiologically, non-P. falciparum malaria infections have been rather neglected because of their less severe clinical symptoms and difficulties of diagnosis. More...

The bottom image shows that when the device was turned on, the nanoparticles were concentrated to the point of becoming visible as a dark line down the center of the chamber (Photo courtesy of Duke University).

Immunoassay Device Based on Acoustic Vortex Nanoparticle Enrichment

An inexpensive acoustic transducer is the key to a novel immunoassay that may eventually be combined with a smartphone camera to form a platform for the rapid detection of diagnostic proteins in blood, urine, or saliva samples. More...
