Reference excerpt

Ramakrishna Podila is an Indian-born American physicist and nanomaterials researcher. He is currently an associate professor of physics in the Department of Physics and Astronomy at Clemson University and is the director of the Clemson Nano-bio lab. He is known for his interdisciplinary research at the interface of physics, biology, and nanoscience. His lab integrates the principles of condensed matter physics, optical spectroscopy, and physiological chemistry to understand physics at the nanoscale and nano-bio interfaces. He became a fellow of the Royal Society of Chemistry (FRSC) in July 2024 and a fellow of the Institute of Physics (FInstP) in May 2025. He currently serves as the chair of the topical group on energy research and applications (GERA) at the American Physical Society.

His work led to new discoveries at the nanoscale such as: 1) time-reversal symmetry breaking with non-linear optical diodes, 2) a novel "wireless" tribo-electric generator that is capable of converting waste mechanical energy into electricity and transmit it wirelessly for storage 3) alleviating quantum capacitance effects in graphene 4) smartphone based rapid inexpensive biosensors for resource-limited settings, and 4) elucidating the origin of nano-toxicity from a fundamental quantum electronic energy levels standpoint.

Research work Podila's research made many strides in fundamental understanding and applications of nanomaterials in energy, health, and photonics.

Energy conversion and storage Podila's group has been attempting to develop highly efficient triboelectric nanogenerators (TENGs) for converting waste mechanical energy into useful electric power; in addition, his group focuses on engineering defects and dopants in nanomaterials to achieve batteries (Li-ion, Li-sulfur, and Al-ion) and supercapacitors (based on nanocarbons and their hybrids with electrochemically active polymers) with high-energy and high-power densities. His work in this area led to many discoveries such as alleviation of quantum capacitance in graphene, wireless tribo-electric nanogenerators, inexpensive TENGs, and novel silicon electrodes for Li-ion batteries among other things. Through their research at the nanoscale, Podila's group has demonstrated the use of defects (including interfaces) for achieving novel functionalities. More importantly, his group successfully translated their research into scalable devices.

Nanotoxicity and nanomedicine Podila's group is presently identifying mechanisms of nanotoxicity with an emphasis on nanoparticle-protein interactions and their influence on physiological responses to ultimately develop benign nanoparticles for medical applications. Podila's collaborative work previously developed an atom-thick coating for preventing blood clots on stents, use carbon nanotubes as drug delivery vehicles for cancer etc. Recently, Podila's work (in collaboration with J. M. Brown group at UC Denver) showed how atomic defects in materials could elicit varying physiological responses by linking nanomaterials, quantum mechanics, and toxicity studies. His work also revealed the fundamental mechanisms by which plaque formation in many diseases such as diabetes etc. can be stopped using nanomaterials.

Biosensing and imaging Podila's group developed novel surface plasmon coupled emission platforms (some of this work done in collaboration with Sri Sathya Sai Institute of Higher Learning) with high sensitivity and specificity for diagnosing low abundance biomarkers. Most importantly, this work led to cheap and inexpensive smartphone sensors for rapidly detecting TB without the need to wait for bacterial cultures. His group invented a new printer paper-based analyte-induced disruption assay that is useful for rapidly detecting antibodies, cancer markers etc. Podila also developed novel fluorescent nanoparticles (doped ZnO, nanocarbons) through three-photon absorption (3PA) for bioimaging of cancer and image-guided surgery.

Worked examples

Example 1 — a first encounter with Ramakrishna Podila

Start with the simplest possible case. Write down what Ramakrishna Podila claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ramakrishna Podila before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ramakrishna Podila ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ramakrishna Podila

In research: Ramakrishna Podila appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ramakrishna Podila in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ramakrishna Podila is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American physicists, 21st-century Indian physicists, 21st-century people from South Carolina, so understanding it makes those chapters shorter.
In everyday life: Look for Ramakrishna Podila outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
