Antibiotic resistance is a major problem in the health sector globally. Many times bacteria form biofilms to resist the action of antibiotics. They do so by adhering together to form a matrix with the help of polymer which they produce. Such microbial films are responsible for failure of devices such as catheters and ventilators.
Researchers at Indian Institute of Technology, Roorkee (IIT-Roorkee) have developed a new eco-friendly nanocomposite that promises to help fight the problem of such antibiotic resistance more effectively. The newly synthesized nanocomposite is capable of penetrating these biofilms and kill microbes.
The new compound has been developed by combining silver particles with ĸ-Carrageenan, a polymer derived from red sea weed. The polymer is conventionally used in food products as a gelling, thickening and emulsifying agent.
Silver nanoparticles are already known to have the ability to kill microbes but they are instable and have a short shelf life. Researchers used ĸ-Carrageenan to increase stability and shelf life of silver nanoparticles. They made a solution of ĸ-Carrageenan with silver nitrate and irradiated it in a microwave synthesizer. The nanocomposite thus obtained was found to be very stable and having a long shelf life, while being effective against both Gram-positive and Gram-negative bacteria.
"Capping of silver nanocomposites with ĸ-carrageenan imparts it stability and shelf life up to six 6 months, which is one of the essential features of therapeutic formulations. The nanocomposite shows excellent antimicrobial activity against S.aureus and P.aeruginosa bacterial biofilms," researchers said. As carrageenan has been widely studied for its antifungal, anti-viral, anti-cancerous and immunomodulatory properties, the nanocomposite based on it can have huge potential in biomedical applications.
The new nanocomposite also has potential applications in food packaging industry as microbial films spoil food products. "We are currently devising cost-effective anti-bacterial wound dressing materials and food packaging materials using the new nanocomposite. We plan to study its efficacy as potent anti-fungal and anti-viral agents too," said Dr.Krishna Mohan Poluri, a member of the research team, while speaking to India Science Wire.
The research results have been published in journal Carbohydrate Polymers. Besides Dr. Krishna Mohan Poluri, the team included Apoorva Goel, Mukesh Kumar Meher, Payal Gupta, Khushboo Gulati and Vikas Pruthi.

A smart phone-based sensors are being developed by the researchers at IIT-H to detect adulteration in milk. As a first step, they have developed a detector system to measure the acidity in milk through an indicator paper that changes colour according to the acidity in the milk. They have also developed algorithms that can be incorporated into a mobile phone to accurately detect the colour change.
Undertaken by a team led by Shiv Govind Singh, professor in Department of Electrical Engineering, IIT-H, comprising associate professors Soumya Jana and Siva Rama Krishna Vanjari, the research has been published in the November issue of the journal Food Analytical Methods.
Speaking of the importance of the research, Prof. Shiv Govind Singh said: "While techniques such as chromatography and spectroscopy can be used to detect adulteration, they generally require expensive set-up and are not amenable to miniaturisation into low-cost easy-to-use devices. Given this, they do not appeal to the vast majority of milk consumers in the developing world. We need to develop simple devices that the consumer can use to detect milk contamination. It should be possible to make milk adulteration detection fail-safe by monitoring all of these parameters at the same time, without the need for expensive equipment."
As a first step, the research team has developed a sensor chip-based method for measuring pH, an indicator of the acidity. They have used a process called 'electrospinning' to produce paper-like material made of nano-sized fibres of nylon, loaded with a combination of three dyes. The paper is "halochromic", that changes colour in response to changes in the acidity.
The team has developed a prototype smart phone-based algorithm in which the colours of the sensor strips after dipping in milk are captured using the camera of the phone, and the data is transformed into pH (acidity) ranges.
They have used three machine-learning algorithms and have compared their detection efficiencies in classifying the colour of the indicator strips.
On testing with milk spiked with various combinations of contaminants, they found near-perfect classification with accuracy of 99.71%.

Carbonated fruit drinks, developed by scientists from the CSIR-Central Food Technological Research Institute (CFTRI), Mysuru, were on display for the first time in public, at the institute's Open Day which began here on Monday.
The institute took around 1.5 years to come out with this product made from technology that adheres to the fruit juice/pulp content as per FSSAI regulations. Fruit pulp/juice extracted from mature ripe fruits was used for the production of the carbonated beverages. An indigenous technology of CFTRI under the Make in India initiative, the product, according to the CFTRI, was acceptable for people of all ages.
The drink comes in a 300 ml bottle and has a shelf life of three months (under room temperature). It can be produced 300 days in a year. Locally available fruits can be used to produce the drink using the technology and can give best returns to the farmers. It has the potential of opening a new market for them.
Visitors tasted the drink served at the Carbonated Fruit Beverage Plant, Mission Directorate, FTT, and gave a thumbs-up to the technology.
"The beverage can be produced from a variety of fruits with different colours and flavours. It has been made in eight flavours ? grape, lime, mango, guava, orange, pomegranate, apple and jamun," said P. Vijayanand, Chief Scientist, Fruits and Vegetable Technology Division, CFTRI, Mysuru. He said that the product is expected to hit the market in December with an entrepreneur from Mysuru having availed a licence from the institute for commercialising the technology.
The fizz in the drink attracts the youth besides driving the consumption of fruit juices among all age groups and improving nutritional quality owing to the presence of fruit pulp, he added.

No firecracker can be absolutely pollution-free, but scientists at the Council of Scientific and Industrial Research (CSIR) have arrived at formulations which may well be categorised as 'Green Crackers' due to their substantially reduced emission levels and their ability to absorb dust.
One of the formulations can even produce water molecules, which suppress dust and significantly reduce hazardous particulate matter.
Besides, prototypes of e-crackers (electronic crackers) are ready for adoption if people are willing to make the switch.
Developed by scientists at CSIR's National Environmental Engineering Research Institute (NEERI), these formulations have been sent to the Petroleum and Explosives Safety Organisation (PESO)- a statutory authority entrusted with framing rules under the Explosives Act, 1884, and the Inflammable Substances Act, 1952."Once PESO approves these formulations, manufacturers will go ahead with production. We can even handhold the manufacturers so that they can quickly scale it up to meet demand," said NEERI director Rakesh Kumar.
