Spirulina: The Ultimate Superfood

Spirulina is an organic superfood that eliminates diseases, reduces cholesterol, and energizes you. If losing weight or eating healthy is important to you, then spirulina is something you might want to look into.

Spirulina was originally found and utilized by Aztecs in the 16th century and later rediscovered in Lake Texcoco by French researchers. It is high in protein, and carries many important antioxidants and vitamins, such as Vitamin B-12 and iron. Unlike many other superfoods, fresh spirulina is odorless and nearly tasteless, making it a great addition to almost any food. In a recent SE3D  experiment, spirulina was mixed with chocolate to create a superfood chocolate print that was indistinguishable from a normal print. Furthermore, it is extremely affordable to buy. Grown on a farm or taken from a lake, this algae is not in short supply. It has no harmful side-effects and is a natural appetite suppressant.

Recently, Robert Henrikson opened the first spirulina farm in Northern Cali…

The chocolate must be warmed up prior to insertion and printing. The bi…


New Methods  A new method in bioprinting has been developed by an Oxford University spin-off company, OxSyBio, that will enable researchers to print and arrange cells in pre-determined 3D architectures. This novel method leverages the use of a lipid coating which encapsulates cells within protective nanolitre droplets during the printing process. Dr Alexander Graham, the lead author and scientist of OxSynBio, demonstrated the application of this technique with human embryonic kidney (HEK) cells and ovine mesenchymal stem cells (hMSCs). He was able to achieve high-resolution 3D geometries in the range of less than 200 microns while maintaining high cell viability. Learn more about this exciting work at their Nature publication – Scientific Reports
New Materials  In the most recent development, a clay-based bioink was developed and shown to provide improved drug delivery properties. A team of researchers from University of Southhampton and the Technische Universitat Dresden in Germany us…

Beginners Guide to Bioprinting: Pluronic as a biomaterial

Here is the first blog to our series of beginners guide to bioprinting. The purpose of this guide is to provide basic knowledge in a topic of interest in the field of bioprinting. This blog will feature the useof Pluronic as a biomaterial for bioprinting.
When using r3bEL to print cellular scaffolds, Pluronic F-127 has been our favored biomaterial. Pluronic, also known as Poloxamer 407, is a hydrophilic non-ionic surfactant,[1] It is also a thermo-reversible hydrogel, meaning that it can change from liquid to solid state depending on the temperature, and in this case, it is a liquid at cold temperatures and a solid at room temperature.

Pluronic is widely used in multiple fields due to its surfactant properties which allow for a lower surface tension between lipids and liquids. In the cosmetics industry, it is used in dissolving oily ingredients in water. Pluronic acts as a cleaning agent to safely remove lipids from the lens films in contacts solution. Pluronic is also quite popular in…

Bioprinting and Biofilm Mimicry: A Student Science Adventure

BiofilmsBiofilms, 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.

Super Scary Superbugs

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 resistance …

3D Printed Food: A Taste of Science

There has always been a marriage of food and science throughout history. Before modern biotechnology was used to produce desired traits in plants and animals, farmers would raise and breed livestock that produced the most milk or best marbling. Food scientists also help determine each ingredient’s optimal condition for harvesting, preservation, and cooking.  From molecular gastronomy to chocolate printing, science has radically changed how we cook, present, and taste food.
3D printers and bioprinters are revolutionizing the food industry by unlocking unlimited potentials for taste, touch and sight.
1.Taste 3D food printers with specific focuses are already in circulation such as the successfully crowd-funded Pancakebot or Bocusini. 3D printing food does not require any sacrifices in taste. In fact with the help of several techniques from molecular gastronomy, 3D printed food has the potential to taste even better than regular foods. There was even a pop up restaurant L…

What does 3D printing bring to future kitchens?

The Technology 
Additive manufacturing has really transformed many areas of our lives today from desktop 3D printers to food printers that could produce custom designed personalized nutritional meals in every home one day. This month, our team has decided to take a closer look at the evolution of Food Printing. As far as food printers go, the use of additive manufacturing techniques spans from the basic extrusion based systems to powder and liquid binding deposition techniques. This allows the end-user to leverage the different material properties to achieve simple to complex shapes that can be created using each technique. In extrusion based food printers which may or may not involve melting, common materials that can be printed are typically soft materials like cheese, peanut butter, dough and chocolate which requires melting. One of the key challenges in this approach is the need for materials that are being printed to be viscous enough to hold its shape under …

My 3D printer can bioprint... right? NOT

By Mayasari Lim, Ph.D.When the r3bEL from SE3D is on display at CES, NSTA or other educational events focused on STEM, the first impression is that it’s another 3D printer like those manufactured by MakerBot or Dremel. As you move in closer and notice that there is no spool for filament, one becomes a bit puzzled and asks the question, “Dr. Lim, this is a 3D printer right?” In some ways but its features and applications are very different than the 3D printers most educators are familiar with. While the r3bEL may have the basic physical structure and platform resembling a 3D printer, it has certain distinct features that cannot be produced in 3D printers typically found in schools. The r3bEL is actually classified as a “bioprinter” for the following; FACT #1 – It does not print plastic! Most desktop 3D printers like MakerBot are based on fused deposition modeling (FDM). It takes in plastic filament and extrudes plastic in a molten form to create 3D objects. It’s commonly used in c…
