Conference Paper
Current diagnostic methods based on nonstructural protein 1 (NS1) for dengue infection use blood as the medium and hence are invasive. Worry for blood infected diseases, pain from pricking, overcrowded public hospitals and ignorance are just a few of the causes for delayed diagnosis that contributes to mortality from dengue fever (DF). NS1 has also...

Conference Paper
Use of SERS spectra to detect NS1 in saliva is a most current finding that could lead to early, non-invasive, non-blood infectious detection of diseases related to NS1. Since the volume of the SERS spectral data is humongous, hence an automated analysis technique to classify the NS1 adulterated samples is vital to the success of this method. K-Near...

Melamine is added to diluted milk to increase the nitrogen content confounding the protein concentration in milk. Milk adulterated with melamine can cause acute renal failure, kidneys damage and death. The presence of melamine in milk can be detected using Raman spectroscopy from its unique feature at 676cm-1 Raman shift. In this study, several sam...

Honey purity can be identified using combinations of Surface-Enhanced Raman Spectroscopy (SERS), digital signal processing and Principal Component Analysis. This paper focuses on the revelation of honey composition and extraction of honey features. The honey was diluted before it was passed to Surface Enhanced Raman Spectroscopy to enhance its spec...
Article
Raman spectroscopy is a vibration based spectroscopic technique for identifying chemical constituent. The Raman signal can be enhanced by binding with metal nanostructures, resulting in so-called surface-enhanced Raman scattering (SERS). Non-structural protein 1 (NS1), a biomarker for flavivirus origin diseases, is found to present in saliva in low...
Conference Paper
Detection of non-structural protein 1 (NS1) in saliva is a recent finding that is appealing to early non-invasive reporting of NS1 related diseases. It is free from risk of blood infection, an advantage over current detection methods which are mostly serum based. Our approach starts with the acquisition of SERS spectra of saliva and saliva adultera...
