(Nanowerk Information) When we have to recharge, we’d take a trip or calm down on the spa. However what if we may recharge on the mobile degree, combating towards getting old and illness with the microscopic constructing blocks that make up the human physique?
The flexibility to recharge cells diminishes as people age or face ailments. Mitochondria, usually known as the powerhouse of the cell, are central to vitality manufacturing. When mitochondrial operate declines, it results in fatigue, tissue degeneration, and accelerated getting old. Actions that when required minimal restoration now take far longer, highlighting the position that these organelles play in sustaining vitality and general well being.
Whereas present remedies for illnesses associated to getting old and ailments like kind 2 diabetes, Alzheimer’s, and Parkinson’s concentrate on managing signs, Texas A&M researchers have taken a brand new strategy to combat the battle on the supply: recharging mitochondrial energy by means of nanotechnology.
Led by Dr. Abhay Singh, a biomedical engineering postdoctoral affiliate within the Gaharwar Laboratory at Texas A&M, the group has developed molybdenum disulfide (MoS2) nanoflowers. Named due to their flower-like construction, these nanoparticles comprise atomic vacancies that may stimulate mitochondrial regeneration, serving to cells generate extra vitality.
The group printed their findings in Nature Communications (“Atomic vacancies of molybdenum disulfide nanoparticles stimulate mitochondrial biogenesis”).

“These findings offer a future where recharging our cells becomes possible, extending healthy lifespans, and improving outcomes for patients with age-related diseases,” mentioned Dr. Akhilesh Gaharwar, Tim and Amy Leach Professor and Presidential Influence Fellow within the Division of Biomedical Engineering at Texas A&M.

In keeping with Gaharwar, the nanoflowers may provide new remedies for ailments like muscle dystrophy, diabetes, and neurodegenerative issues by rising ATP manufacturing, mitochondrial DNA, and mobile respiration. They found that the atomic vacancies within the nanoflowers stimulate the molecular pathways concerned in mitochondrial cell replication.
Analysis collaborators embody Texas A&M college and college students. From the Division of Biophysics and Biochemistry, Dr. Vishal Gohil supplied insights into the mechanisms that might drive the development of mitochondrial operate.
“This discovery is unique,” Dr. Gohil mentioned. “We’re not simply enhancing mitochondrial operate; we’re rethinking mobile vitality solely. The potential for regenerative medication is extremely thrilling.”

Different Division of Biomedical Engineering contributors embody Dr. Hatice Ceylan Koydemir, assistant professor, and Dr. Irtisha Singh, an affiliate assistant professor within the Division of Molecular and Mobile Drugs. Singh contributed computational evaluation that exposed key pathways and molecular interactions chargeable for the vitality increase.
“By leveraging advanced computational tools, we can decode the hidden patterns in cellular responses to these nanomaterials, unlocking new possibilities for precision medicine,” Singh mentioned. “It’s like giving cells the right instructions at the molecular level to help them restore their own powerhouses—mitochondria.”
The subsequent steps for the analysis group embody figuring out a way for delivering the nanoflowers to human tissue, with the aim of eventual scientific software.
“In science, it’s often the smallest details that lead to the most profound discoveries,” Gaharwar mentioned. “By focusing on the unseen — like atomic vacancies in nanomaterials — we are uncovering new ways to solve big problems. Sometimes, the real breakthroughs come from digging deeper and looking beyond the obvious.”
