Environmentally benign production of graphene suspensions

A method of producing a graphene suspension, comprising: (a) mixing multiple particles of a graphitic material and multiple particles of a solid carrier material to form a mixture in an impacting chamber of an energy impacting apparatus; (b) operating the energy impacting apparatus with a frequency and an intensity for a length of time sufficient for peeling off graphene sheets from the graphitic material and transferring the graphene sheets to surfaces of the carrier material particles to produce graphene-coated carrier particles inside the impacting chamber; and (c) dispersing the graphene-coated carrier particles in a liquid medium and separating the graphene sheets from the carrier material particles using ultrasonication or mechanical shearing means and removing the carrier material from the liquid medium to produce the graphene suspension. The process is fast (1-4 hours as opposed to 5-120 hours of conventional processes), environmentally benign, cost effective, and highly scalable.

Nanoparticle conjugated synthetic opioid prodrugs and methods of their uses

Provided herein are nanoparticle conjugated synthetic opioid prodrugs that target the peripheral mu opioid receptor (MOR). The prodrugs exhibit long-lived bioavailability, do not compromise the analgesic effects of opioids administered for pain relief (and in some cases can be used for pain relief), and do not induce opioid withdrawal symptoms, when their use is discontinued. Certain of the prodrugs are especially useful for the prevention and/or treatment of unwanted opioid-induced side effects such as opioid-induced constipation (OIC).
