Here, trace DNA collection tools and rapid on-site DNA analysis kits that can enhance the efficiency of forensic investigations through the application of advanced convergent technology are coming!
...
They include a nano swab for effectively collecting trace DNA samples at crime scenes,
rapid identification kits for major body fluids in a single step,
and an isothermal amplification kit for the efficent screening of forensic evidence.
...
By prioritizing the analysis of key evidence items that can provide valuable information for suspect identification and case resolution from a wide range of human derived materials encountered at crime scenes, one can enhance the efficiency of investigations in terms of time and cost.
Nanoswab and hydrogel swab for trace DNA collection (on-site product demonstration)
This swab is effective in increasing the surface area of the swab by using silica nanoparticles and hydrogel, thereby enhancing the efficiency of collecting trace biological materials at the crime scene.
- It improves the DNA yield compared to commerical swabs without affecting DNA quality. (Forensic validation completed!)
Paper-based colorimetric sensors and antibody-based repid test kits for body fluid identficiation (on-site product demonstration)
- The kits are paper and antibody-based on-site rapid test kits that allow for the quick and simple confirmation of the presence of saliva, blood, and semen through color changes.
- These kits can offer reduced testing time and cost savings compared to commercial testing products.
- Korean Patent application number 10-2023-0076607 (2023.06.15)
Loop-mediated isothermal amplification (LAMP) kits for point-of-care evidence screening; male, saliva and ABO blood group) (on-site product demonstration)
- Utilizing the isothermal amplification (LAMP) system, which allows for rapid amplification of the target compared to conventional PCR reactions performed in the laboratory, these kits enable on-site confirmation of (1) the presence of male-derived materials, (2) the presence of saliva, and (3) the ABO blood type of blood specimens.
- Korean Patent application number 10-2022-0113229 (2022.09.07)
- Korean Patent application number 10-2022-0122272 (2022.09.27)
