DNA evidence has linked a Hollywood man to the rape of a woman who was targeted while taking trash out to a motel dumpster, police say.

Jamal Hanna, 28, was charged with sexual assault and kidnapping after a lab report "stated that with reasonable scientific certainty" he was considered the source of the DNA found on the woman who was raped, a Hollywood police report said.

Police responded to the sexual assault shortly before 3 a.m. Sept. 27, 2013, after the woman escaped from her attacker through a bathroom window that she broke and crawled through, the report said. She managed to convince Hanna to allow her to shower after the assault and cut her thigh badly on glass shards as she fled, the report said.

Police found her in the 1600 block of North Federal Highway near the motel where the rape happened, officials said.

The woman's ordeal began when she was approached by a stranger while she tossed garbage in the dumpster. Hanna put his hands around her throat and forced her to a darkened area behind the motel, where he made her perform a sex act, the report said.

Hanna then took her to a motel room where he forced her to have sex and sodomized her, police said. She persuaded him to give her time in the bathroom to clean up. She escaped through the window she shattered while wearing only a bath towel, according to police. Along with a large cut on her inner thigh, the woman also had bruising on her neck and arms.

After being treated for her injuries, DNA samples were taken from her at the sexual assault treatment center.

Last month, Hanna, who was considered a possible suspect, consented to allowing police to take DNA samplings from him. When compared, Hanna's DNA matched up to the DNA found on the woman, according to a crime analysis lab report received on April 15, authorities said.

Hanna was arrested Monday. During his first-appearance court hearing Tuesday, he told the judge he had been living in South Florida for about a year and three months and was currently employed as a mechanic.

Hanna was ordered held without bond "based on the level of violence, based on the facts of the case," said Broward Judge John "Jay" Hurley.

Rape at Hollywood motel solved by DNA, police say

It's a familiar trope in science fiction: In enemy territory, activate your cloaking device. And real-world viruses use similar tactics to make themselves invisible to the immune system. Now scientists at Harvard's Wyss Institute for Biologically Inspired Engineering have mimicked these viral tactics to build the first DNA nanodevices that survive the body's immune defenses.

The results pave the way for smart DNA nanorobots that could use logic to diagnose cancer earlier and more accurately than doctors can today; target drugs to tumors, or even manufacture drugs on the spot to cripple cancer, the researchers report in the April 22 online issue of ACS Nano.

"We're mimicking virus functionality to eventually build therapeutics that specifically target cells," said Wyss Institute Core Faculty member William Shih, Ph.D., the paper's senior author. Shih is also an Associate Professor of Biological Chemistry and Molecular Pharmacology at Harvard Medical School and Associate Professor of Cancer Biology at the Dana-Farber Cancer Institute.

The same cloaking strategy could also be used to make artificial microscopic containers called protocells that could act as biosensors to detect pathogens in food or toxic chemicals in drinking water.

DNA is well known for carrying genetic information, but Shih and other bioengineers are using it instead as a building material. To do this, they use DNA origami -- a method Shih helped extend from 2D to 3D. In this method, scientists take a long strand of DNA and program it to fold into specific shapes, much as a single sheet of paper is folded to create various shapes in the traditional Japanese art.

Shih's team assembles these shapes to build DNA nanoscale devices that might one day be as complex as the molecular machinery found in cells. For example, they are developing methods to build DNA into tiny robots that sense their environment, calculate how to respond, then carry out a useful task, such as performing a chemical reaction or generating mechanical force or movement.

Such DNA nanorobots may themselves sound like science fiction, but they already exist. In 2012 Wyss Institute researchers reported in Science that they had built a nanorobot that uses logic to detect a target cell, then reveals an antibody that activates a "suicide switch" in leukemia or lymphoma cells.

For a DNA nanodevice to successfully diagnose or treat disease, it must survive the body's defenses long enough to do its job. But Shih's team discovered that DNA nanodevices injected into the bloodstream of mice are quickly digested.

"That led us to ask, 'How could we protect our particles from getting chewed up?'" Shih said.

Nature inspired the solution. The scientists designed their nanodevices to mimic a type of virus that protects its genome by enclosing it in a solid protein case, then layering on an oily coating identical to that in membranes that surround living cells. That coating, or envelope, contains a double layer (bilayer) of phospholipid that helps the viruses evade the immune system and delivers them to the cell interior.
