Overseer of Research for the Forensic and National Security Sciences Institute (FNSSI) in the College of Arts and Sciences, Marciano as of late added to the National Institute of Justice May 2022 Forensic Technology Center of Excellence report, “A Landscape Study Examining Technology and Automation for Differential Extraction and Sperm Separation for Sexual Assault Investigations.” An educated authority who procured his doctorate at Syracuse, Marciano wrote a part called “Syracuse University Examined the Use of the DEPArray System to Assess Challenging Sexual Assault Kit Samples.”

In the most straightforward terms, the ongoing technique for social occasion scientific proof from rape casualties includes recovering examples, which are then tried for DNA. Assuming DNA is found, it is placed into the FBI’s DNA Index System, which permits policing look for matches that can distinguish potential guilty parties, interface cases together or give other basic data that might assist with tackling violations. This has for some time been the standard course of DNA testing, yet it is tedious and doesn’t normally have the capacities to distinguish DNA from tiny examples or those gave over 72 hours after a rape.

In 2013, Marciano was moved toward by a previous partner who inquired as to whether he may be keen on testing another piece of hardware with the capacities to all the more likely identify DNA. Marciano has given his vocation to this kind of work, having begun in an investigative laboratory at the Onondaga County (New York) Center for Forensic Science. He then continued on toward be a senior researcher at innovative work organization SRC prior to joining the University, where he currently abroad examination for FNSSI. The chance to attempt this new innovation was something he was unable to deny.

The DEPArray NxT System was created by Italian company Manarini Silicon Biosystems for use in cancer research, but it has since been found to have additional uses. According to Marciano, it separates the epithelial (or skin) cells and sperm cell prior to extraction through a process that can more quickly and efficiently calculate the total number of epithelial cells and sperms cells, as well as the amount of DNA in a sample, while also removing possible impurities.

Moreover, the DEPArray makes it conceivable to recognize DNA in any event, when tiny examples of sperm are found, from tests required following 72 hours or in situations where there are blended examples in with various donors — things current techniques frequently can’t identify.

“At FNSSI, we have finished up to 200 sudden spikes in demand for these instruments. We know how they work, front to back, and we are wanting to expand the responsiveness for the scientific local area and try and possibly offer types of assistance,” Marciano says. “It’s our main goal to continue to help development in legal hereditary qualities and pushing it ahead. It’s interesting work!”

While the technology offered by the DEPArray is promising, the challenge is that its results are currently not accepted in a court of law.

“The techniques currently set up are time tested, and there is generally protection from transform,” he says of the norms of the overall set of laws. “Scholastic specialists such as myself need to gather sufficient proof behind this new innovation to demonstrate that it truly does whatever is necessary become piece of standard legitimate cycles and be progressed into the criminological world.”

Meanwhile, he, with the assistance of understudies working at FNSSI, proceed to test and report the DEPArray framework’s abilities.

“Our understudies are the principal on the planet to involve this innovation in a legal setting,” Marciano makes sense of. “They finish the experience that is in each investigative laboratory on the planet through FNSSI and furthermore get to contrast that with the techniques we’re seeing with the DEPArray. Our understudies will go into occupations after graduation with firsthand involvement with this advanced innovation. Also, I like to feel that they will take that experience to move criminology like this significantly further.”

Marciano plans to continue his work with the DEPArray, having already published two articles and working on a third, while also applying for National Institute of Justice grants to access additional funding to support his research in this area.

“The hope is that the DEPArray will soon become a game changer in examining critical biological evidence in sexual assault cases that will make a real difference to victims and those in the forensic science community,” he says. “It’s fascinating and important, and I’m privileged to be a part of it.”
