Single Cell Injections
Duke University physicists have developed a way to produce sharp fluid jets with enough precision that they can inject material into a single, living cell. The technique promises a way to deliver drugs to cells one at a time, which is likely to be very valuable for research involving stem cells and other cellular-level studies. The research appears in the current issue of the APS journal Physical Review Letters.
The physicists produced the jets by focusing lasers into a fluid surrounding a target cell. The lasers heated molecules of a blue dye dissolved in the fluid, which in turn created tiny bubbles to rapidly grow and collapse. When these sorts of bubbles are produced individually, they create shock waves that spread throughout the liquid. But producing two adjacent bubbles in rapid succession results in small, powerful jets capable of poking tiny holes, measuring only 0.2 millionths of a meter across, in cell membranes.
The researchers confirmed that the jets allowed the introduction of fluids into the cell by checking for signs of the blue dye inside the pierced cells. The dye is toxic, and it killed the pierced cells, but the holes the jets produced were small enough that it’s likely that the jets will offer a way to inject live cells with nontoxic substances without significantly damaging them.
Claus-Deiter Ohl of Nanyang Technological University in Singapore provides further information about the fluid jets and related research in a Viewpoint article in the current edition of APS Physics.

This article is about getting fluids into a single, living cell. They are doing this because it is promises a way to deliver drugs to cells at a time. The physicists produce jets by using lasers to heat the molecules that create tiny bubbles. The powerful jets poke tiny holes only .2 millionths of a meter. Last, the toxic dye goes into the cells and injects them with nontoxic substances without significantly damaging them.
~Physicists from Duke University created a way to inject fluid into cells. They will use this technology to give drugs. They do this by focusing lasers at a fluid next to the cell. The research confirm that this process. However the dye is toxic and killed the punctured cells. This problem should not be a problem with live cells.
I think its impressive that we are now able to inject drugs into such a small mirco sized cell. Hopefully it will bring some good use the world in dealing with uncureable diases(or however you spell it)

Scientists at the University of Duke have discovered a new way to make sharp fluid jets, with alot of presision, so that they can inject it into a single, living cell. This new “invention” has a way of delivering drugs to a cell one at a time. They did this by putting lasers in a fluid surrounding a target cell. The lasers that they had created heated molecules of a blue dye, which dissolved in a blue liquid. Researchers acknowledeged that the jets allowed the introduction of fluids in the cell by checking for signs of the blue dye inside of the cells.
Physicists from duke university seem to have developed a way to produce sharp fluid jets to inject things into a single living cell.The lasers created tiny bubbles to rappidly grow and collapse.

This arcitle was mainly about the physicists at Duke University that found a way to inject single celled organisms. They found a way to focus lasers into a surrounding fluid that surrounds the target cell. When they did this the cell died because they injected it with a blue dye, but this led them to know that they can inject other things into the cell and it still live. It seems like a complex process but i’m sure it will have its benifits.
The Duke University mae jets. Jets that will produce materials in a cell one by one. My opinion is who would wanna get pricked thousans of times in the first place. Then they found out the blue dye they used the first or second time killed the cell.And know they are trying to find a way to put non toxic materials into the cell so it won’t dye off.
Duke University physicists have developed a way to produce sharp fluid jets with enough precision that they can inject material into a single, living cell. This is done with a laser that creates tiny bubbles.The technique promises a way to deliver drugs to cells one at a time.

This article talks about the physicists at Duke University and their discovery to produce sharp fluid jets with enough precision that they can actually inject material into a single, living cell. This process ensures a way to deliver drugs to cells all at one time. The jets are designed specifically with lasers focusing into a fluid surrounding a target cell. The down side is that the dye is toxic, and will kill the pierced cell. They are trying to figure out a way to make the dye nontoxic so it won’t damage the animal.
Duke University found a way to inject single celled organisms. The physicists produced the jets by focusing lasers into a fluid that is surrounding a target cell. The lasers heated molecules of a blue dye that dissolved in the fluid. That turned created tiny bubbles to rapidly grow and collapse. When these sorts of bubbles are produced individually, they create shock wave that spread throughout the liquid.
The scientist at Duke university have invitened a way to inject singel cell organisms. Offerntantly the dye they used infected the cell causing it to die. They are now trying to find a way to use non toxic chemicals because it could come in hand in the future.
Duke University physicists have fond a way to make sharp fluid jets with enough precision that they can inject material into a single, living cell. It now has a way to deliver drugs to cells one at a time.The researchers have said that the jets allows the introduction of fluids into the cell by checking for signs of the blue dye inside the pierced cells. I think that this is a good article because now they can produce fluid into one single cell.
This article is about injecting liquid into a cell. They use a set a laser, that are focused on a target cell. The holes created where only 0.2 millionths of a meter.
The lasers heat the molecules of a blue, toxic dye. The studies showed that scientist will be able to inject nontoxic liquids with the jets.
the article is about how at duke university they can now cure one single cell with a small tube. this tube has so much persision that i think it will be able to help cure cancer. it also says that they used jets to prodused focused lasers in to a fluid surroding a target cell.i also think that they will be able to cure a lot a teriminal diseases with this proces more advanced though.

Duke University physicians have found a way to to produce fluid jets so they can inject materials into cells. This will let scientists inject medicine into cells one at a time. The physicians made the jets by focusing a laser into a fluid surrounded by a target cell. They have confirmed that the jets allow injectionof fluids into the cell by checking the blue dye that should be in the cells. The dye is toxic and it kills the pierced cells. The jets produce holes so that is can inject nontoxic substances into living cells without damaging the significantly.
