Isolation of PCR ready-human DNA using copper nanoparticles from skeletal remains

Area of Science:

• Forensic Science
• Biotechnology
• Nanotechnology

Background:

• DNA extraction from skeletal remains is crucial for personnel identification but often challenging.
• Existing methods can be time-consuming, expensive, or involve hazardous chemicals.

Purpose of the Study:

• To develop a rapid, cost-effective, sensitive, and non-hazardous DNA extraction method.
• To utilize copper nanoparticles (CuNPs) for efficient DNA isolation from skeletal remains.

Main Methods:

• Copper nanoparticles (CuNPs) were synthesized using microwave irradiation.
• The CuNP-based DNA extraction method was tested on blood samples and subsequently on skeletal remains.
• DNA quality and suitability for PCR were assessed.

Main Results:

• The method successfully yielded good quality, PCR-ready human DNA from small quantities of blood and skeletal remains.
• The DNA extraction process was rapid, cost-effective, and sensitive.
• The use of small quantities of CuNPs proved highly efficient.

Conclusions:

• Microwave-synthesized CuNPs offer a novel and efficient approach for DNA extraction from skeletal remains.
• This method is robust, environment-friendly, and eliminates the need for hazardous organic solvents.
• The technique holds potential for applications in forensic science and the analysis of ancient DNA samples.
