Indian scientists have come up with a new combination of polymers that can be used as a hydrogel to make the process of wound healing faster.

The main advantage of the new hydrogel is that mixing of the two polymers causes rapid gelation at the body temperature of 37 degrees Celsius itself and at the same time does not generate much heat. Generation of heat during the gelling process can lead to tissue death in the area surrounding the injection site. This will be avoided.

Speaking to the India Science Wire, Suresh Kumar Jewrajka of CSIR-Central Salt and Marine Chemicals Research Institute (CSMCRI) at Bhavnagar, Gujarat, who is one of the researchers involved in the development said, “The new hydrogel also leaves no byproduct. Hence, it is biocompatible. Further, it is biodegradable making it well suited for wound healing and tissue regeneration”.

The combination developed by the scientists consists of a modified version of polyethylene glycoland a reactive block copolymer of poly[(2-dimethylamino)ethyl methacrylate] and poly(N-isopropyl acrylamide). The two compounds react and form a hydrogel in less thanfour minutes.

The results were published in the internationally renowned science journal `Materials Chemistry B`. The journal is brought out by UK’s Royal Society.

The combination is a hydrogel. Hydrogels have a special property of absorbing water and becoming a semisolid gel at body temperature. This helps to maintain it in a liquid state in the vial and solidifying into a gel when applied on a wound or injecting near the site of an injury.

In a few minutes, the liquid becomes a gel that aggregates platelets and prevent loss of blood. This aids wound closure. It also has the ability to incorporate antibiotics and provides sustained release of the drug at the injury site.

Other scientists who contributed to the study were Arvind Singh Chandel and Nutan Bhingradiafrom CSMCRI, and Shailja Singh and Deepika Kannan from Shiv Nadar University, Uttar Pradesh.

They are now taking the research forward by testing it on mice. “We need to do extensive experiments to test its utility in clinical applications. Our future work will also deal with making elastic and crystalline hydrogels for tissue regeneration”, the scientists told India Science Wire.

Delhi-NCR air quality

The Delhi government has announced a large-scale deployment of mist sprayer technology to tackle rising air pollution, with Chief Minister Rekha Gupta confirming that 305 mist sprayers will be installed across nine pollution hotspots in the capital.

Mist sprayers to curb dust at critical locations

During an inspection at ITO, Gupta said the mist sprayers already operational at the site are performing effectively. She noted that 35 poles at ITO have been fitted with these machines, which are helping suppress dust—a major contributor to air pollution in Delhi.

According to the Chief Minister, trials conducted in certain NDMC areas have shown promising results, reinforcing confidence in the technology.

High-level committee to guide pollution-control measures

Gupta announced the formation of a high-level expert committee that will advise the government on effective measures to reduce pollution. The panel will include senior officials from various departments as well as environmental specialists, including experts from IITs. Officials stated that the committee will receive special powers to implement pollution-mitigation strategies.

Departments directed to repair roads, add greenery

The Chief Minister said departments including PWD, DSIIDC and DDA have been instructed to fix potholes, repair and carpet roads, plant foliage along dividers and islands, and take other measures to reduce pollution sources.

She urged residents to report potholes on the government portal for quicker action.

Appeal to RWAs to prevent biomass burning

To curb winter pollution, Gupta advised Resident Welfare Associations (RWAs) to distribute electric heaters to security guards to discourage biomass burning, which significantly contributes to seasonal pollution spikes.

PM Modi welcomes Vladimir Putin with warm hug as Russian President begins India visit

Russian President Vladimir Putin began a high-profile visit to India on Thursday, welcomed by PM Narendra Modi as both nations prepare to discuss defence, energy and trade cooperation.

Vladimir Putin rides in Indian PM Narendra Modi's car on India visit

Russian President Vladimir Putin arrived in New Delhi on Thursday evening for a 27-hour visit focused on strengthening defence, energy and trade cooperation. The visit, marked by a warm embrace and a brief car ride shared with Prime Minister Narendra Modi, underscores the continuity of the India-Russia strategic partnership amid shifting global geopolitics.

Putin receives ceremonial welcome and packed schedule ahead

Putin landed in Delhi around 6:35 pm, where PM Modi personally received him at Palam airport. The two leaders shared a hug before leaving together, with the Prime Minister set to host a private dinner in honour of the visiting President — a reciprocal gesture to the hospitality extended during Modi’s Moscow visit last year.

On Friday, Putin will begin his official engagements with a ceremonial welcome at Rashtrapati Bhavan, followed by a visit to Rajghat to pay homage to Mahatma Gandhi. He is also scheduled to attend the India-Russia Annual Summit at Hyderabad House, where both sides will hold a working lunch.

The Russian President will later inaugurate a new India-based channel of Russia’s state broadcaster and attend a state banquet hosted by President Droupadi Murmu, before departing India on Friday night.

Defence, energy and trade to dominate agenda

Officials have indicated that discussions will centre on defence, energy and trade — the three pillars of the bilateral relationship. Agreements are expected across sectors including shipping, healthcare, fertilisers and connectivity.

Ahead of the summit, defence ministers from both countries held extensive talks, covering additional procurement of S-400 air defence systems and delayed military hardware shipments affected by the Ukraine war. The S-400 platform, procured under a USD 5 billion deal, played a major role during Operation Sindoor.

The Kremlin has also hinted that Russia may propose the Su-57 fifth-generation fighter jet, which would put Moscow in direct competition with Western aircraft makers.

Energy ties face renewed pressure

India remains among the largest buyers of discounted Russian crude. However, fresh US sanctions on key Russian oil producers have led to a dip in purchases.

Putin’s visit also comes at a time of strain in India-US ties, with Washington recently imposing steep tariffs on Indian goods — including measures linked directly to India’s continued oil trade with Russia.

Massive security deployment in Delhi

Delhi Police have stationed over 5,000 personnel across central and New Delhi districts, supported by SWAT teams, anti-terror units, snipers, quick-reaction teams, anti-drone systems, HD-CCTV networks and layered surveillance measures for the visit.

Rahul Gandhi attacks Centre ahead of Vladimir Putin’s India visit

Rahul Gandhi alleged that the government discourages visiting foreign dignitaries from meeting Opposition leaders, calling it a sign of “insecurity,” hours before Russian President Vladimir Putin arrives in Delhi.

Rahul Gandhi

As Russian President Vladimir Putin arrives in Delhi today for the India-Russia Annual Summit, Leader of the Opposition Rahul Gandhi has renewed his charge that the Centre discourages visiting foreign leaders from meeting Opposition representatives. He called it a sign of “insecurity” within the government.

Rahul Gandhi alleges break in long-followed tradition

Speaking outside Parliament, Rahul Gandhi said that it has traditionally been the norm for visiting foreign leaders to meet the Leader of the Opposition, a practice he claims continued during the tenures of Atal Bihari Vajpayee and Manmohan Singh.

He alleged that the present government advises foreign dignitaries against such meetings. “When foreign leaders come, the government suggests they should not meet the Leader of the Opposition. This is their policy,” Gandhi said. He added that a meeting with the Opposition offers visiting leaders a broader perspective, as “we too represent India.”

Gandhi further stated that this approach reflects the government’s reluctance to allow engagement between the Opposition and foreign guests.

Former Foreign Secretary counters Gandhi’s remarks

Responding to Gandhi’s allegations, former Foreign Secretary and Rajya Sabha MP Harsh Vardhan Shringla said visiting leaders operate on very tight schedules and there is no protocol mandating a meeting with the Leader of the Opposition. He stressed that such interactions depend entirely on the guest’s time and preference, noting that the required meetings are those with the President and the Prime Minister.

Putin’s schedule packed with bilateral engagements

Russian President Vladimir Putin is set to land in Delhi this evening on Prime Minister Narendra Modi’s invitation. His itinerary includes:

  • A private dinner with PM Modi
  • Visit to Mahatma Gandhi’s memorial at Raj Ghat
  • Engagements at Bharat Mandapam and Hyderabad House
  • A banquet hosted by President Droupadi Murmu

The visit forms part of the 23rd India-Russia Annual Summit.
