Biofilms Biofilms, complex extracellular structures created by bacterial colonies, pose a serious threat to human health. They are responsible for survival and antibiotic resistance of many bacteria, and lead to serious infectious diseases such as cystic fibrosis and endocarditis. Preventing or destroying biofilms is an important area of research, and could help cure these diseases. A major challenge in studying biofilms is our ability to create them reproducibly and precisely in the laboratory so that experimental results are reliable. The r3bEL Bioprinter can mimic biofilms through culturing and printing bacteria in an alginate medium onto a petri dish or another substrate. These highly reproducible biofilm mimicries can then be tested for effects of key variables  and of antibacterial substances.

Superbugs refer to strains of bacteria that cannot be killed using multiple antibiotics. Per the CDC (Centers for Disease Control and Prevention), roughly 2 million people get sick from superbugs every year and about 23,000 of them die. An elderly American woman died in the US recently after having contracted an infection while being treated for a thigh bone fracture in India two years ago. Tests showed no drug or combination of drugs available in the US would have cured the infection. But where did these superbugs come from and why are they a problem now? Origin Antimicrobial resistance (AMR) is the ability of a microbe to resist the effects of medication previously used to treat them. It is a result of misusing antibiotics and evolution at work. Misusing antibiotics is when antibiotics are taken when they aren’t needed or not finished when they are needed. This leads to antibiotics becoming less effective for future bacterial infections and the development of antibiotic resis
