HOT Article: improved brain tumour diagnosis

21 Sep 2012

By Vibhuti Patel, Deputy Editor.

Diagnostic segregation of human brain tumours using FT-IR and Raman

Gajjar et al., Anal. Methods, 2012, Advance Article

Scientists at Lancaster University and Lancashire Teaching Hospitals NHS Trust have used infrared and Raman spectroscopy for brain tumour diagnosis.

Professor Frank Martin and colleagues used the techniques combined with statistical analysis to discriminate between normal brain tissue and three different tumour types based on the unique spectral fingerprints of their biochemical composition.

Current diagnostic approaches lack the spatial resolution required by surgeons, and delineating the excision border is important in making sure the tumour is completely removed. Vibrational spectroscopy has potential for analysing brain tissue, and Raman in particular can be performed in vivo within seconds or minutes. The information obtained by this method can be combined with conventional methods, for example immunohistochemistry, to diagnose and grade brain tumours to allow for more accurate planning and execution of surgery and/or radiation therapy. This offers more potential for individualised treatment and better long-term survival.

Professor Martin says, “These are really exciting developments which could lead to significant improvements for individual patients diagnosed with brain tumours. We and other research teams are now working towards a sensor which can be used during brain surgery to give surgeons precise information about the tumour and tissue type that they are operating on.”

HOT article: Improving the stationary phase for HPLC

05 Sep 2012

By Rebecca Brodie, Deputy Editor.

Liang et al., Anal. Methods, Advance Article

Silica-based stationary phases are very commonly used for high performance liquid chromatography but in most cases cannot be used above pH of 8. There have been a number of approaches used, mainly including post-synthesis grafting and direct synthesis, to improve the high pH stability of silica-based stationary phases. In this paper, Xinmiao Liang and colleagues from Dalian Institute of Chemical Physics have used porous spherical silicon oxynitride (sph-SiON) material as a stationary phase for HPLC. Read more about their work below.

HOT Article: New Development for Amphetamine Drug Detection

04 Sep 2012

By Pui Sai Lau, Web Writer

Mashayekhi et al., Anal. Methods, 2012, Advance Article

With the prevalent misuse of amphetamine and its derivatives, drug testing is routinely performed in clinical and forensic laboratories. Effective testing requires high efficiency and reproducibility for analysis of complex, real samples. Hossein Ali Mashayekhi and colleagues from Islamic Azad University, Iran, have created a novel strategy to detect amphetamine and its related compounds in human urine by using ultrasound-assisted emulsification microextraction and gas chromatography.
