High-frequency sound waves have been used in a laboratory device to turn a liquid containing mesenchymal stem cells into an aerosol. The 2016 study showed that the platform could nebulize cells while preserving several measured cell properties; it did not show that inhaling stem cells treats lung disease in people.
What does “sound” have to do with lung treatment?
Here, “sound” means high-frequency surface acoustic waves (SAWs) generated on a microfluidic device. The waves act on a liquid containing cells and help form an aerosol that could, in principle, be inhaled. This is not listening to sound or applying sound therapy to a patient.
The work was reported by Alhasan, Qi, Rezk, Yeo and Chan in Integrative Biology in 2016. The authors evaluated whether their acoustomicrofluidic nebulization platform could aerosolize mesenchymal stem cells (MSCs) without substantially damaging them. The paper is available from the Royal Society of Chemistry; its bibliographic record and abstract are also indexed by PubMed.
What did the experiment find?
At a tested operating point of 1.5 W, the researchers reported a nebulization rate of 100 μL per minute and approximately 90% cell viability after 24-hour reculture. These are results for the experimental device and its laboratory conditions, not measures of patient benefit or a recommended clinical dose.

- DOCTOR RECOMMENDED AND PERSONALIZED CARE: Delivers nasal safe solutions and prescribed medications as a fine mist using compressed air technology for 98% more deep coverage of the nasal cavity (per product labels or as prescribed by a HCP)
- EASY AND UNDER 30 SECONDS : Add any nasal safe solution or prescribed medication to the NasoNeb cup, insert the tip into your nose and start the compressor for consistent coverage with powered airflow, takes 30 seconds or less per nostril
- FSA/HSA ELIGIBLE SINUS CARE SYSTEM: Includes compressor, nebulizer cup and tubing set, one free 30 ml moisturizing nasal solution; FSA or HSA eligible for treating ongoing sinus and nasal symptoms at home with medical grade nebulization technology
- DESIGNED FOR DEEP REACH: Engineered to deliver 98% more solution to the middle and back of the nose than standard irrigation devices like sprays, rinse bottles, or powered irrigation devices without nebulization, for relief of sinus and allergy symptoms
The team assessed cell viability, morphology, metabolic activity, proliferation, and genetic and phenotypic characteristics using cellular and molecular assays. The results supported the feasibility of producing an MSC-containing aerosol while preserving several measured characteristics relative to controls.
There was a trade-off: increasing applied power increased the nebulization rate but reduced cell viability. The reported operating point therefore reflects a balance between aerosol production and the cells’ measured survival, rather than proof of an optimal setting for treatment.

Why use acoustic nebulization?
The study describes surface acoustic waves operating in the order of 10–100 MHz, while conventional bulk ultrasonic nebulizers operate at 10 kHz to 1 MHz. Frequency alone does not establish that one method is safer or more effective; the relevant question is how a delivery method affects fragile cells and the resulting aerosol.

According to the paper, jet and conventional ultrasonic nebulizers can expose cells to stresses such as shear, cavitation, and heat. Electrospray is another delivery approach discussed by the authors, but it requires high-voltage potentials. The acoustic platform was presented as a way to investigate cell nebulization while limiting damage, with portability as a potential advantage. These are technical considerations, not evidence that the platform outperforms other methods in clinical care.

Can sound waves deliver stem cells to the lungs?
The experiment supports a limited answer: a microfluidic device using high-frequency acoustic waves can aerosolize a liquid containing MSCs and preserve several properties measured in laboratory assays. It does not establish that inhaled MSCs reach diseased lung tissue in a useful way, improve lung function, or safely treat people.
The authors noted that inhaled stem-cell therapy was novel and that comparing delivery methods was difficult. The study was an assessment of a delivery platform, not a clinical trial demonstrating a treatment. Its findings do not establish a patient-facing product, clinical availability, or a recommendation to use a nebulizer for stem-cell delivery.
What to take from the 2015 headline
Chemistry World published Liisa Niitsoo’s news report “A sound idea for treating lung disease” on 8 December 2015, before the primary paper appeared in 2016. The headline describes a research direction, not an available therapy. The durable takeaway is that acoustic microfluidics offered a promising laboratory method for making cell-containing aerosols; whether that can become a safe and effective treatment requires evidence beyond this study.
