Photoactivated Proximity Protein Labeling Reveals Enhanced Tumor Retention of a D‐Peptide‐Ruthenium Prodrug Conjugate

open access: yesAdvanced Healthcare Materials, EarlyView.
Six stereoisomeric ruthenium‐peptide conjugates were synthesized and characterized, which showed high potential in photoactivated chemotherapy (PACT) and proximity protein labeling. Abstract Amino acid chirality is known to influence the biological properties of peptide‐containing prodrugs.

Quiescence: a mechanism for escaping the effects of drug on cell populations [PDF]

open access: yes, 2010
We point out that a simple and generic strategy to lower the risk for extinction consists in the developing a dormant stage in which the organism is unable to multiply but may die. The dormant organism is protected against the poisonous environment.

Multivalent Protein Nanorings for Broad and Potent SARS‐CoV‐2 Neutralization

open access: yesAdvanced Healthcare Materials, EarlyView.
A protein‐only, modular multivalent nanoscaffold displaying 20 anchor points, decorated with two different binders (10 of each), targeting the SARS‐CoV‐2 receptor‐binding domain is presented. The construct self‐assembles into stable, biocompatible, homogeneous nanoparticles, exhibit synergistic binding with fM IC50 values. It also detects spike at 9 ng

Reducing the extinction risk of stochastic populations via non-demographic noise

open access: yes, 2018
We consider non-demographic noise in the form of uncertainty in the reaction step size, and reveal a dramatic effect this noise may have on the stability of self-regulating populations.

Decision Making Under Extinction Risk

open access: yesCognitive Psychology
In everyday life, people routinely make decisions that involve irredeemable risks such as death (e.g., while driving). Even though these decisions under extinction risk are common, practically important, and have different properties compared to the types of decisions typically studied by decision scientists, they have received little research ...

Microbubble Shell Stiffness Engineering Enhances Ultrasound Imaging, Drug Delivery, and Sonoporation

open access: yesAdvanced Materials, EarlyView.
 Shell‐engineered poly(alkyl cyanoacrylate) microbubbles with tunable stiffness improve ultrasound imaging and therapy. Adjusting the length of the alkyl chain and the glass transition temperature maintains a narrow microbubble size distribution while enhancing drug loading, sonoporation and the acoustic response.

On population extinction risk in the aftermath of a catastrophic event

open access: yes, 2008
We investigate how a catastrophic event (modeled as a temporary fall of the reproduction rate) increases the extinction probability of an isolated self-regulated stochastic population.
