Alcohols as solution for delaying microbial degradation of biological evidence on cotton swabs

Phuengmongkolchaikij S, Panvisavas N, Bandhaya A
Forensic Sci Int Genet Suppl Ser 2017;6:e539-e41
DOI: 10.1016/j.fsigss.2017.09.198

"The outcome of this study could be used to suggest an alternative DNA evidence collection and storage method in remote areas where samples must be transported in non-ideal conditions to central labs for analysis."

Salmonella enterica multilocus sequence typing and its correlation with serotypes

Pethplerdprao P, Supa-amornkul S, Panvisavas N, Chaturongakul S
Food Biotechnology 2017; 31(2):73-79
DOI: 10.1080/08905436.2017.1301820

"Salmonella enterica is a foodborne pathogen and has also been ranked among the top five most significant bacterial agents of foodborne illnesses by the Ministry of Public Health. MLST is a powerful Salmonella subtyping method which could be used not only as a tracking tool for an outbreak investigation at nucleotide level but also as a serotype predictor for making correlations with food safety regulations."

Simple and rapid screening of the thiocyanate level in saliva for the identification of smokers and non-smokers by capillary electrophoresis with contactless conductivity detection

Phonchai A, Srisukpan T, Riengrojpitak S, Wilairat P, Chantiwas R
Analytical Methods. 2016:4983-90
DOI: 10.1039/C6AY01460G

"A method for thiocyanate biomarker analysis employing capillary electrophoresis with contactless conductivity for saliva is proposed as a rapid screening method. The method required less than 3.5 min per sample."

TaqMan qPCR for detection and quantification of mitochondrial DNA from toxic pufferfish species

Luekasemsuk T, Panvisavas N, Chaturongakul S
Toxicon.2015.102;43-7
DOI: 10.1016/j.toxicon.2015.05.016.

"The designed TaqMan primer and probe set can detect at least 4 pufferfish genera. The detection limit is at as low as 1.75 pg of gDNA. Developed assay can specifically detect and quantify pufferfish gDNA within 1 h."

Invention application (No. 1303001601) has been filed for this work through Mahidol niversity Center for Intellectual Property Management.

Identification of human DNA in forensic evidence by loop-mediated isothermal amplification combined with a colorimetric gold nanoparticle hybridization probe

Watthanapanpituck K, Kiatpathomchai W, Chu E, Panvisavas N
Int J Legal Med. 2014;128(6):923-31.
DOI: 10.1007/s00414-014-1018-9

"A simple DNA extraction method for the commonly found forensic biological samples was also devised to streamline the test process. This LAMP-AuNP human DNA test showed to be a robust, specific, and cost-effective tool for the forensic identification of human specimens without requiring sophisticated laboratory instruments."

Elemental analysis of burnt human bone for classifying sex and age at death by logistic regression

Sawasdee K, Tiensuwan M, Siripinyanond A, Chirachariyavej T, Smith SM
Analytical Methods. 2012;4:1769-75.
DOI: 10.1039/C2AY05763H

"The chemical information in burnt bone fragments could be employed to assess the sex and age groups of the deceased with 79.60% and 75.10% accuracy, respectively. Chemical measurements were performed on burnt bone samples from two additional individuals to verify the developed logistic equations and classification protocol. More fractions of bones from an individual give a higher percentage of correction for classifying sex and age at death of the deceased."

Magnetic Fingerprint Powder from a Mineral Indigenous to Thailand

Thonglon T, Chaikum N
J Forensic Sci 2010;55(5):1343-6
DOI: 10.1111/j.1556-4029.2010.01432.x

"A magnetic fingerprint powder has been prepared by mixing powdered natural magnetite with nickel powder in a ratio of approximately 1:100. Dusting fingerprints with the mixed powder gave developed fingerprints of quality comparable to those obtained by using a commercial black magnetic powder, judging from the number of minutiae detected by the AFIS. The cost of the prepared powder is less than one‐third of that of the commercial magnetic powder."
