SERS based magnetic immunoassay for cancer biomarker HE4

Schematic diagram of magnetic immunoassay based on SERS

Women with gynaecological malignancies are at high risk of developing ovarian cancer (OC). OC does not show any symptoms in the early stages, resulting in a delay in detection and definite diagnosis is obtained in the later stages. At present, ultrasonic imaging and assay of biomarkers (e.g. Human epididymis protein 4, HE4 ) are used for the diagnosis of OC. But the ultrasonic imaging can not discriminate between benign and malignant tumours and the immunoassays are time consuming, require sophisticated equipment and skilled professionals. Therefore, there is an urgent need for the development of a sensitive method for trace assay of biomarkers such as HE4. Jianlin Yao and colleagues from the Soochow University have developed a new approach based on surface enhanced Raman spectroscopy (SERS) and a magnetic immunoassay technique for rapid detection and separation of HE4 with high sensitivity and selectivity. ‘ The immuno nanoparticles studied could be developed as reagent kits in the clinical diagnosis of cancer’, opines Jianlin Yao. To learn more about the study, read the full article for free* by following the link given below.

Forbidden Fruit Now Edible: New Mass Spectrometry Approach for Food Pesticide Detection

To ensure high crop yield, the addition of pesticides to crops may seem like a necessary evil. However, most applied chemicals have adverse side-effects to our health. Consequently, simple, effective, and accurate methods of pesticide detection is critical for safe food consumption. Unfortunately, most direct methods of pesticide detection that do not require sample preparation can only provide qualitative results. Furthermore, methods that are capable of quantitative analysis require complicated, time-consuming procedures of sample preparation prior to analysis. Anastasia Albert from the University of Muenster, Carsten Engelhard from the University of Siegen and other colleagues from Germany have evaluated ambient desorption/ionization high-resolution mass spectrometry (ADI-HR-MS) for quantitative pesticide detection in fruit, and have devised a streamlined procedure for effective analysis. Find out more about their discovery by accessing the link below:
