Researchers demonstrate the intricate interactions between single-stranded DNA sequences and carbon nanotubes

BUSAN, South Korea, July 26, 2024 /PRNewswire/ — Single-walled carbon nanotubes (SWCNTs) have emerged as promising candidates for applications in biotechnology and nanoelectronics due to their exceptional physical and chemical properties. Despite their potential, challenges like insolubility and toxicity have hindered their widespread use. Prior studies have been investigating diverse strategies to functionalize and modify the surfaces of SWCNTs to overcome these challenges.

In a recent study, researchers from the Pusan National University led by Professor Sanghwa Jeong, Assistant Professor in the School of Biomedical Convergence Engineering, have attempted to fill this gap. This study has gone beyond conventional techniques by employing high-throughput screening methods to elucidate the relationship between DNA sequences and their binding affinity to carbon nanotubes. It focused on optimizing the binding affinity and stability of these constructs through advanced sequence design and molecular dynamics simulations. This recent study was published in the journal of Advanced Science on 25th June 2024. Discussing the background of their study Dr. Jeong explains, “Researchers have been exploring various strategies to engineer SWCNT surfaces to overcome the challenges of limited applications owing to insolubility and potential toxicity. One promising approach is the use of single-stranded DNA (ssDNA) as a wrapping surfactant for SWCNTs.”

The researchers employed a rigorous methodology to ensure precise characterization and optimization of single-stranded DNA (ssDNA)-SWCNT complexes. Initially, a diverse random 30-nucleotide (nt) ssDNA library underwent iterative rounds of screening to identify high-affinity sequences.

Computational modeling, particularly molecular dynamics simulations, provided insights into the structural dynamics of the SWCNT constructs. Furthermore, the researchers used several machine-learning models to understand the pattern of sequences that affect binding affinity. They have successfully created a freely accessible online service that predicts the binding affinity of ssDNA sequences to SWCNTs. These integrated approaches not only validated the experimental findings but also guided the design of high-performance ssDNA-SWCNT constructs.

The findings revealed significant advancements in the stability and functionality of ssDNA-SWCNT complexes. High-affinity 30-nt ssDNA sequences, rich in adenine and cytosine, exhibited superior binding strength, validated through surfactant displacement experiments. Molecular dynamics simulations highlighted the formation of stable intramolecular hydrogen bonds near the SWCNT surface, underscoring their enhanced structural integrity. The machine-learning models effectively predicted the binding affinities of ssDNA sequences, further supporting the design of the tailored ssDNA-SWCNT constructs.

Moreover, the study demonstrated notable improvements in the resistance of these complexes to enzymatic degradation compared to free ssDNA, making them highly suitable for long-term biological applications.

In conclusion, the development of high-affinity ssDNA-SWCNT constructs marks a significant advancement in nanobiotechnology. The exceptional characteristics of ssDNA-SWCNTs make them ideal candidates for cell or tissue-specific drug delivery systems as well as the development of high-performance nano electronic devices.

Dr. Jeong concludes, “Our study not only makes a substantial contribution to our understanding of the interplay between ssDNA and SWCNTs but also offers practical avenues for harnessing these interactions in a wide range of advanced technologies. In the future, developing nanomaterials and devices with enhanced stability will show promise in driving innovation in nanoelectronics and biotechnology.”

Sembly AI launches Sembly 3.0 in biggest evolution since 2019

SYDNEY, Sept. 8, 2026 /PRNewswire/ — Today, Sembly AI launches Sembly 3.0, an agentic AI platform that transforms an organisation’s documents, meetings, and CRM content into finished, fully branded presentations, proposals, case studies and reports in minutes in over 45 languages.

The launch marks the company’s biggest evolution since it was founded in 2019, repositioning Sembly as an “AI execution layer” for businesses. It turns everyday business knowledge into the finished materials companies use to sell, deliver and communicate.

Users simply need to specify their goal (eg, “Sell my services”) and the client’s website, then watch Sembly get to work: pulling information from business materials, deriving appropriate branding, researching the customer, and producing a bespoke on-brand pitch deck.

“Prompts make people think about how to talk to AI. But dialogue lets them focus on what they want to accomplish,” said Gil Makleff, CEO and co-founder of Sembly AI. “That makes creating business documents faster and more efficient, turning time saved into real business impact.”

“Manually creating presentations is a thing of the past,” said Artem Koren, Chief Product & Technology Officer and co-founder of Sembly AI. “Business materials are the substrate of decision-making: they are how companies communicate, persuade and decide. Sembly 3.0 changes how they are made entirely.”

“Your customers want to hear how you serve them in their specific world and their specific situation, and Sembly makes that possible for every customer,” Koren added. “With Sembly 3.0, your results are as good as how clearly you can state your goal. That’s all you’re limited by.”

Early users of Sembly 3.0 report saving two to three weeks of work on reports and presentations that traditionally pass through multiple hands before they are delivery-ready.

Heorhii Tulchyi, Chief Technology Officer at market research company, Bell & Holmes, is one of those early users of Sembly 3.0.

He said: “Sembly has fundamentally changed how I prepare presentations and client communications. It has saved my team and me weeks of work and dramatically accelerated how we turn ideas and information into polished deliverables. I haven’t seen anything else on the market quite like it.”

Sembly 3.0 is available from today at www.sembly.ai.

Lion Announces Plan to Implement ADS Ratio Change

Published

By

SINGAPORE, Sept. 7, 2026 /PRNewswire/ — Lion Group Holding Ltd. (“Lion” or “the Company”) (NASDAQ: LGHL), operator of an all-in-one trading platform that offers a wide spectrum of products and services, today announced that it plans to change the ratio of its American Depositary Shares (“ADSs”) to its Class A ordinary shares (the “ADS Ratio”), par value US$0.0000001 per share, from the current ADS Ratio of two hundred ninety-two thousand and five hundred (292,500) Class A ordinary shares, to a new ADS Ratio of one (1) ADS to five million eight hundred and fifty thousand (5,850,000) Class A ordinary shares (the “ADS Ratio Change”). The Company anticipates that the ADS Ratio Change will be effective on or about September 10, 2026 (the “Effective Date”).

For the Company’s ADS holders, the change in the ADS Ratio will have the same effect as a one-for-twenty reverse ADS split. On the Effective Date, registered holders of company ADSs held in certificated form will be required on a mandatory basis to surrender their certificated ADSs to the depositary bank for cancellation and will receive one (1) new ADS in exchange for every twenty (20) existing ADSs then-held. Holders of uncertificated ADSs in the Direct Registration System (“DRS”) and in The Depository Trust Company (“DTC”) will have their ADSs automatically exchanged and need not take any action. The exchange of every twenty existing ADSs for one (1) new ADS will occur automatically, with existing ADSs being cancelled and new ADSs being issued by the depositary bank on the Effective Date.

Lion’s ADSs will continue to be traded under the ticker symbol “LGHL” on the Nasdaq Capital Market. No fees will be charged to ADS holders, for both certificated or uncertificated ADSs, in connection with the exchange of existing ADSs for new ADSs.  No fractional new ADSs will be issued in connection with the change in the ADS Ratio. Instead, fractional entitlements to new ADSs will be aggregated and sold by the depositary bank and the net cash proceeds from the sale of the fractional ADS entitlements (after deduction of fees, taxes and expenses) will be distributed to the applicable ADS holders by the depositary bank. The ADS Ratio Change will have no impact on Lion’s underlying Class A ordinary shares, and no Class A ordinary shares will be issued or cancelled in connection with the ADS Ratio Change.

As a result of the change in the ADS Ratio, Lion’s ADS trading price is expected to increase proportionally, although the Company can give no assurance that the ADS trading price after the ADS Ratio Change will be equal to or greater than twenty (20) times the ADS trading price before the change.
