Project Overview
Virtus-Parva is a team of Nanotechnology students who aim to create a better world through love,sympathy and endearment… and through the design and development of a novel technology based on micrometric “drills” to attack pathogen agents.
First and foremost, we studied different procedures in order to synthesize the strongest and smallest magnetite particles we could make. Magnetite is a molecule that derives from iron, and has observable magnetic properties. Because we wanted to put together magnetite and DNA, we had to make them compatible, task we accomplished by functionalizing it with amino groups, that would allow it to form peptide bonds with our protein, HU. At the same time, our biology team was busy extracting, purifying and transforming E. Coli DNA to work with. This protein, HU, is a histone-like protein normally aids DNA into supercoiling around histones; the “Magnetic-Protein” complex we created mimics the nucleosome in DNA supercoiling process. This allows us to have a DNA “chromatin” with a magnetic core.

The Idea
The basis for these “drills” will be NEMS, nano electro-mechanical systems, technology.
We took a survey to fellow iGEMers and external people in order to find out how many people knew about the existence of NEMS and if they knew how they worked. Turns out only 36% of survey takers had heard of the term before and of those, only 28% knew what it was!
Given these statistics, it became part of our project to teach newer generations about our subject.
NEMS
NEMS are nanometric electromechanical systems. In this case we take as basis the structure of a resonator which are engineered to make a conversión between energy, such as electric, magnetic, or vibrational into mechanical response.
How exactly do NEMS come into play in our project?
Well, by combining an inorganically synthesized nanoparticle, called magnetite and DNA into what we call BioNEMS drill.
