Antibacterial gel bandage created from durian husk

The durian is a strange-looking tropical fruit with a greenish-yellow exterior coated fully in spikes. Meals scientists from NTU Singapore have used the discarded husks of the tropical fruit to create an antibacterial gel bandage. The fruit’s spiky outer husk is discarded whereas the candy flesh inside surrounding the seeds is eaten and regarded a delicacy.

Researchers can extract high-quality cellulose from the durian husks and mix it with glycerol, which is a waste byproduct from biodiesel and soap-making industries, to create a delicate gel that’s much like silicon sheets. The sheets might be minimize into bandages of varied dimensions and shapes. Researchers added natural molecules produced from a yeast often known as pure yeast phenolics to instill antibacterial properties into the dressing.

Hydrogel patches are widespread and accessible at pharmacies. They’re usually used to cowl wounds ensuing from surgical procedure to reduce scar formation by protecting the pores and skin hydrated. Typical hydrogel patches accessible immediately are created from artificial supplies like polymers, together with polymethacrylate and polyvinylpyrrolidine. Bandages with antimicrobial properties use metallic compounds like silver or copper ions.

The brand new hydrogel is cheaper than artificial supplies accepted to be used in biomedical functions. Researchers on the undertaking say that the ever-increasing menace of antibiotic-resistant micro organism means the world wants a number of options to forestall infections. An efficient method to defend open wounds is by utilizing antimicrobial bandages which might be biocompatible and secure for extended use by people.

The husk of the durian may be very thick and includes 60 p.c of the fruit. It’s usually discarded and incinerated, creating an environmental subject. Utilizing the waste materials to create the bandages helps clear up any environmental points the fruit creates. The ensuing proof of idea product was examined as a wound dressing on animal pores and skin and confirmed antimicrobial results for as much as 48 hours.
