Inside the 47th Annual Meeting Transforming Medicine
Imagine being able to watch individual molecules at work inside a living cell, witness proteins folding in real-time, or observe how diseases disrupt cellular machinery at the atomic level.
This isn't science fiction—it's the cutting edge of biophysics, a field that uses physics principles to solve biological mysteries. Every year, the brightest minds in this transformative discipline gather at the Biophysical Society Annual Meeting, and their 47th gathering in Los Angeles promises to be their most dramatic yet.
Dubbed "Biophysics Goes Hollywood," this year's meeting features groundbreaking research that reads like a script for the next medical revolution: nanoscale tools that track individual molecules in living cells, advanced imaging that captures proteins in atomic detail, and computational models that predict how diseases disrupt cellular function 1 . These developments aren't just academic exercises—they're paving the way for smarter drug design, personalized medicine, and fundamental discoveries about how life functions at the molecular level.
Fundamental areas of biophysics continue to deliver compelling insights while embracing new technologies.
Emerging fields generating particular excitement at this year's meeting.
Innovative methods pushing the boundaries of what we can observe and measure.
Membrane biophysics, which studies the gatekeepers of our cells, now incorporates high-resolution imaging and single-molecule manipulation to observe how proteins interact with lipid membranes in real-time 3 . Similarly, research on receptors and channels has evolved from basic characterization to dynamic visualization of these molecular machines at work, revealing how they convert chemical signals into cellular actions 1 .
These classical domains are experiencing a renaissance thanks to new technologies that allow researchers to ask more precise questions and get more detailed answers than ever before.
Scientists can now manipulate individual molecules and measure their properties and biological functions both in solution and within cells 3 .
By combining multiple techniques like cryo-electron microscopy, mass spectrometry, and computational modeling, researchers can build comprehensive 3D pictures of biological machines.
This approach connects events at the atomic level to cellular and even tissue-level phenomena, creating a comprehensive picture of biological processes 1 .

One of the most significant challenges in modern medicine involves properly characterizing complex biological drugs like gene therapies and messenger RNA vaccines. These advanced treatments are far more heterogeneous than traditional drugs, creating an urgent need for analytical methods that can assess their quality and consistency.
Dr. Evolene Desligniere and her team at Paris-Saclay University are tackling this challenge using two innovative techniques: charge detection mass spectrometry (CDMS) and mass photometry 2 . Their work represents a crucial step toward ensuring the safety and efficacy of next-generation therapeutics.
Researchers began by preparing samples of adeno-associated viruses (AAVs) used in gene therapy, glycoproteins, and messenger RNA molecules 2 . These were diluted to appropriate concentrations for analysis.
Both the CDMS and mass photometry instruments were calibrated using standards of known mass and charge to ensure accurate measurements.
Unlike conventional techniques that average signals across many molecules, these methods analyze particles individually:
Thousands of individual particles were measured to build comprehensive distributions of mass and size, revealing the heterogeneity within each sample.
Results from both techniques were compared to assess consistency and validate findings across different physical principles.
The experiments yielded unprecedented insights into therapeutic quality that would remain hidden with conventional methods.
| Capsid Type | Mass Range (MDa) | Percentage |
|---|---|---|
| Full Capsids | 3.5-4.5 | 30-70% |
| Empty Capsids | 2.5-3.2 | 20-60% |
| Partial Capsids | 3.2-3.5 | 5-15% |
| mRNA Sample | Measured Mass (kDa) | Quality |
|---|---|---|
| Properly Capped mRNA | 355-445 | High |
| Uncapped mRNA | 305-395 | Medium |
| Degraded mRNA | Broad distribution | Low |
The true power of this experiment emerged from the complementary nature of the two techniques. While mass photometry provided rapid assessment of sample heterogeneity, CDMS delivered absolute mass measurements without needing reference standards. Together, they formed a comprehensive toolkit for quality assessment that could guide manufacturers in optimizing production processes.
Perhaps most importantly, this work demonstrated that we now have tools capable of characterizing the inherent complexity of next-generation therapeutics rather than oversimplifying them. This acknowledgement and quantification of heterogeneity represents a paradigm shift in how we evaluate sophisticated biological drugs.
Modern biophysics relies on specialized reagents and technologies that enable precise observation and manipulation of biological systems.
Tag and visualize biomolecules for tracking protein movement in live cells and monitoring conformational changes 3 .
Bright, photostable fluorescent labels for glycobiology studies, tracking membrane receptors, and long-term imaging 6 .
High-throughput protein stability screening for thermal stability measurements and aggregation temperature determination 2 .
Multiplexed biophysical characterization for comprehensive stability profiling of antibodies, membrane proteins, and enzymes 2 .
Coarse-grained molecular dynamics simulation for modeling multimillion-molecule systems like entire virus particles 6 .
Manipulate single molecules with laser light for studying protein folding and molecular motor forces 3 .
As the 47th Annual Meeting demonstrates, biophysics is experiencing a revolutionary period where technological innovations are enabling answers to questions that were once unapproachable.
From tracking individual molecules in living cells to modeling entire viral particles in silico, the field is breaking down barriers between physics, biology, and medicine.
The implications extend far beyond basic research. The tools and discoveries highlighted at this meeting are already driving medical advances in cancer treatment, genetic therapies, and drug development. As one researcher noted, "Biophysics has done an excellent job making advances in experimental techniques over the past couple decades. But we've often failed to apply these new tools to contribute to actual medical innovation. Between these new experimental tools and novel theoretical work, we can improve on this in future decades" 8 .
The meeting's Hollywood theme proves surprisingly appropriate—just as film technology continues to evolve, allowing storytellers to bring increasingly sophisticated visions to the screen, biophysical technologies are giving scientists the power to reveal and manipulate the molecular dramas that underlie all of life. In both cases, we're witnessing a blockbuster era of innovation that promises to transform how we see our world—or in the case of biophysics, worlds within us that we're only beginning to explore.
