This High Schooler Invented Color-Changing Sutures to Detect Infection

By Theresa Machemer

Dasia Taylor has juiced about three dozen beets in the last 18 months. The root vegetables, she’s found, provide the perfect dye for her invention: suture thread that changes color, from bright red to dark purple, when a surgical wound becomes infected.

The 17-year-old student at Iowa City West High School in Iowa City, Iowa, began working on the project in October 2019, after her chemistry teacher shared information about state-wide science fairs with the class. As she developed her sutures, she nabbed awards at several regional science fairs, before advancing to the national stage. This January, Taylor was named one of 40 finalists in the Regeneron Science Talent Search, the country’s oldest and most prestigious science and math competition for high school seniors.

“I’ve done a lot of racial equity work in my community, I’ve been a guest speaker at several conferences,” says Taylor. “So when I was presented with this opportunity to do research, I couldn’t help but go at it with an equity lens.”

Before the Covid-19 pandemic, Taylor spent most of her time after school in the Black History Game Show, a club she’s been a member of since eighth grade, and attending weekly school board and district meetings to advocate for an anti-racist curriculum. For the four months leading up to her first regional science fair in February 2020, Taylor committed Friday afternoons to research under the guidance of her chemistry teacher, Carolyn Walling.

Healthy human skin is naturally acidic, with a pH around five. But when a wound becomes infected, its pH goes up to about nine. Changes in pH can be detected without electronics; many fruits and vegetables are natural indicators that change color at different pH levels.

“I found that beets changed color at the perfect pH point,” says Taylor. Bright red beet juice turns dark purple at a pH of nine. “That’s perfect for an infected wound. And so, I was like, ‘Oh, okay. So beets is where it’s at.’”

Next, Taylor had to find a suture thread that would hold onto the dye. She tested ten different materials, including standard suture thread, for how well they picked up and held the dye, whether the dye changed color when its pH changed, and how their thickness compared to standard suture thread. After her school transitioned to remote learning, she could spend four or five hours in the lab on an asynchronous lesson day, running experiments.

A cotton-polyester blend checked all the boxes. After five minutes under an infection-like pH, the cotton-polyester thread changes from bright red to dark purple. After three days, the purple fades to light gray.

Working with an eye on equity in global health, she hopes that the color-changing sutures will someday help patients detect surgical site infections as early as possible so that they can seek medical care when it has the most impact. Taylor plans to patent her invention. In the meantime, she’s waiting for her final college admissions results.

“imma keep hold black male responsible” shut the fuck up. here’s some fucking history for your rhino looking ass. the constitution (have you fucking heard of it), gave WHITE PROPERTY OWNING MEN the right to vote. one more time for your donkey meth dick sucking ass, WHITE PROPERTY OWNING MEN. no a single black person (male or female) had any-fucking-thing to do with that shit in 1789.

it wasn’t until the 41st us congress that black males got the right to vote via 15th amendment. you know how many black people were a part of that congress? that congress in 1869?! zero bitch! ze-fucking-o you inbred spam sandwich. the first black congressman didn’t happen until 1870. you do know how to count right?

the 15th amendment was about the republican party’s goal of making sure blacks could vote in the north AND the south since president grant at the time only won presidency because of the black vote in the south. you see the constitution gave individual states the power to set voting requirements. that why some states allowed black to vote while others didn’t. however white men who still didn’t respect women of any race decided to ratify the 15th amendment to allow for men to vote regardless of race or past enslavement. one more time for your before picture looking ass, these were all white men doing this shit in 1869 so how the fuck you talking about holding black men responsible? if we had so much power that we could give or take voting rights from white women, then how did poll taxes, literacy tests and grandfather clauses happen? these were enacted for the sole purpose to restricting the black vote esp in the south. most were in place until 1964. so black people had so much power to keep white women from getting voting rights and yet we kept poll taxes and shit in place harming us for almost a damn fucking century?! you walking ghost pale advertisement for condoms, how the fuck does that even make sense? where in your history book did you read that those racist white suffragettes were going around making pleas to black men? where? when? in fact that right to vote you’re so fucking proud of excluded black women and native women. native americans were not even granted citizenship until 1924. and, discriminatory jim crow laws, coupled with a resurgent and violent ku klux klan, had a firm grip in the southern states. african-american women in the deep south could no more exercise their right to vote in 1920 than african-american men after the passage of the 15th amendment in 1870. in-truth, you grotesque gargoyle, white women relied HEAVILY on racism to get their voting by making sure to exclude all non-white people from their movement. white men knew that they had a good system in place to keep the black vote suppressed but giving all women (including black women) the right to vote would undermine that hence why white women excluded black and brown people from their movement to reassure white fucking racists. if you actually took the time to do just a little study on the topic (i know that’s hard for someone with the iq of a stepped on cockroach) you would see that white congressmen where doing everything they could to keep from giving y’all the right to vote because they didn’t want black people to get more power. hell a mississippi senator named james vardaman wanted to give white women the right to vote and then repeal the 15th amendment, barring all “negroes, both male and female, from the politics of america.” but you know, it was black males who were doing this right? you hideous three legged crack mule.

i could go on but i’ve made my point. you talking cancer puss, get your fucking facts straight. your white sensitive ass need to just shut the fuck up and take responsibility from your racist ass ways. looking like pimple sperm. shut the fuck up.

Do not use the website called Sci-Hub!

It lets people access scientific articles for free. This is dangerous. It helps the free flow of knowledge and reduces the competitive edge of all the people who worked really hard to have been born into a wealth.

Like, it’s literally a website where you can type in the DOI of an article and read it, without ever having to pay the publisher who exploited the author.

Deity (Complete) By: Freya Ishtar - M, 16 chapters - Draco's come to suspect he might have Veela blood, after all, and that his mate might be a girl he's tried to protect, despite loathing her. Yet, the truth of his lineage is far more unique than that, and Hermione will learn how much fun that truth can be. Though even their fun comes at a price as she also learns a truth about herself she never imagined possible.

BROOOO

i included a photo below beside my switch for comparison of how big the xl and overnight pads are (i love using both for for nighttime use). daily, i use my regular pads and when working out/post-period, i use the liners.

the amazing part is that it’s 5 LAYERS AND COMES WITH TWO BUTTONS TO SNAP TOGETHER!!

I AM SO IN LOVE!! HERE’S THE LINK IF YOU GUYS ARE INTERESTED!!!!

Requesting others reblog to spread word.
